BASIC ELECTRICAL/ELECTRONIC HAND TOOLS

DRIVING TOOLS

​1. Screwdrivers - are hand tools specifically designed to insert and tighten, or to loosen and remove screws.

A screwdriver comprises a head or tip, which engages with a screw, a mechanism to apply force by rotating the tip, and some way to position and support the screwdriver, the tip of which is shaped in to fit a particular type of screw.

a. Slotted Screwdriver is used to drive or fasten negative slotted screws.

​b. Phillips Screwdriver – used to drive or fasten positive slotted screws. It is a screwdriver that could take greater torque and could provide tighter fastenings.

c. Jeweler's Screwdriver Set – is a set of small screwdrivers composed of slotted and Phillips screwdrivers.

SOLDERING TOOLS

1. Soldering Iron – is a device for applying heat to melt solder in attaching two metal parts. A soldering iron is composed of a heated metal tip and an insulated handle. For electrical work, wires are usually soldered to printed circuit boards, other wires, or small terminals. A low-power iron (20-30 Watts) is suitable for this work.

2. Soldering Tool Stand – is a place where the soldering iron is placed during usage. This will keep the soldering iron away from flammable materials. The stand often comes with a sponge used in cleaning the tip of the soldering iron.

​3. Desoldering tool - is used in removing soldered wires and components on printed circuit boards for troubleshooting and repair purposes.

​Splicing Tools

1. Long Nose - is used for holding, bending, and stretching the lead of electronic components or connecting wires.

2. Side Cutter - is a wire-cutting plier, though they are not used to grab or turn anything, but are used to cut wires.

​ 3. Wire Stripper - is a pair of opposing blades much like scissors or wire cutters. The addition of a center notch makes it easier to cut the insulation without cutting the wire.

BORING TOOLS

1. 12V Mini-Drill – is used to bore or drill holes in the printed circuit board (PCB) with sizes from 1/32” – 1/16”.

2. Portable Electric Drill - is used for boring hole(s) in plastic or metal chassis with the use of drill bits having sizes from 1/6” to approximately 1/4”.

​3. Metal Files - These are hand tools having a series of sharp, parallel ridges or teeth. Most files have a narrow, pointed tang at one end to which a handle can be fitted.

• Flat File is parallel in width and tapered in thickness; they are used for flat surfaces and edges.

• Half Round File is tapered in width and thickness, coming to a point, and is narrower than a standard half round and used for filing inside of rings.

• Round File - is also called rat-tail file which is gradually tapered and used for many tasks that require a round tool, such as enlarging round holes or cutting a scalloped edge.

CUTTING TOOLS

1. Utility Knife - is a common tool used in cutting various trades and crafts for a variety of purposes.

2. Hacksaw - is used for cutting metals. Some have pistol grips which keep the hacksaw firm and easy to grip. The small hand-held hacksaws consist of a metal arch with a handle that fits around a narrow, rigid blade.

​

AUXILIARY TOOLS

1. Magnifying Glass - is a convex lens which is used to produce a magnified image of an object. The lens is usually mounted on a frame with a handle. Roger Bacon is the original inventor of the magnifying glass. A magnifying glass works by creating a magnified virtual image of an object behind the lens. Some magnifying glasses are foldable with built-in light.

​2. Paint Brush – made of bristles set in a handle, used for cleaning dirty parts of a circuit or an object.

ELECTRONIC EQUIPMENT

Aside from hand tools, equipment is also needed for more accurate and quality output. In this connection, three of the most used equipment are presented here for you to be familiar with their uses and the proper way of maintaining them.

1.Volt-Ohm-Milliammeter. It is an equipment that combines three functions: as a voltmeter that measures both ac and dc voltages; an ohmmeter that measures resistance; and milliammeter that measures small amount of dc current. As safety precautions in the maintenance of this instrument, the following should be observed:

• Always rest the function switch at 250V AC if an OFF position is not available in the instrument.

• For current and voltage measurements, always set the function switch in the correct setting which is a little higher than the expected current or voltage present in the circuit.

• Place the instrument in a cool dry place, away from any magnetic devices, and free from vibrations.

2. Oscilloscope. An oscilloscope (commonly abbreviated CRO, for cathode-ray oscilloscope, or scope) is a piece of electronic test equipment that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis).

​3. Signal generator. A signal generator is a device which produces simple waveforms. Such devices contain an electronic oscillator, a circuit that is capable of creating a repetitive waveform. These are typically used in simple electronics repair and design where they are used to stimulate a circuit under test. Oscilloscope and signal generator should be given regular checkup for at least once a week by connecting them in the power line. This will help prevent their components from having moisture that might cause trouble in their circuits.

COMMON FAULTS IN USING HAND TOOLS

PLIERS:

• Do not increase the handle length of pliers to gain more leverage. Use a larger pair of pliers or bolt cutters if necessary.

• Do not substitute pliers for a wrench when turning bolts and nuts. Pliers cannot grip these items properly and might cause a slip and create an accident.

• Never use pliers as a hammer on the handle. Such abuse is likely to result in cracks or breaks.

• Cut hardened wires only with pliers designed for that purpose.

• Always cut the wires at the right angle. Never rock from side to side or bend wire back and forth against the cutting edges.

SCREWDRIVERS:

• Never use screwdrivers as a pry bar, chisel, and punch stirrer or scraper.

• Never use screwdrivers with broken or worn-out handles. Screwdrivers of these kinds should have tags to indicate that it is defective.

• Never use pliers on a screwdriver for extra leverage. Only use wrench or screwdrivers specifically designed for purpose.

UTILITY KNIVES/ BLADES:

• Do not use dull blades because they require more force, thus are more likely to slip. Replace the blade when it starts to “tear” instead of cut.

• Never leave a knife unattended with the blade exposed.

• ​Don’t bend or apply side loads to blades by using them to open cans or loosen the tight cover of containers. Blades are brittle and can snap easily.

HOW DO I PREPARE FOR A PROJECT?

Whenever you’re preparing for a project – especially if it requires specialized tools – be sure to pre-plan and think about which tools you’ll need instead of using makeshift tools and equipment.

1. Break it down. Before you begin, break down your project into simple steps. Do some research if necessary and figure out which tools you will need for each step.

2. Determine hazards. By anticipating potential hazards before you begin, you’ll be able to plan for safe procedures and equipment while working, instead of thinking on-the-fly.

Check it over. You may be surprised to learn how many people are injured each year simply from using old ladders and equipment. Once you have your equipment laid out, be sure to inspect it to ensure everything is in working order. Is that ladder old and rickety? Find a replacement. Dull saw blade? Time to run to the hardware store.

HAND TOOLS SAFETY

Hand tools are a common piece of equipment that is needed on construction sites of all kinds. Even at home, hand tool use is very common for many different kinds of jobs that are needed. There are many records that can be found on the dangers that can occur when using hand tools.

A lot of the time, the hand injuries or bodily injuries that are endured are due to improper use or neglecting to follow instructions that were given. Some of the most simple and straightforward hand tools can cause harm when used incorrectly. It is important to also make sure hand tools are inspected regularly for repairs, malfunctions, or any other problems they may have. In this article, we will go over all the basic hand tools that may be used in construction, how to inspect them, and best safety practices.

COMMON HAND TOOLS

There are many tools aside from power tools that are used every day in construction sites and at home. Some of the most commonly used hand tools are, but not limited to:

• Hammers

• Chisels

• Wrenches

• Screwdrivers

HAND TOOL INSPECTIONS

Regular tool inspections are ideal to prevent unnecessary injuries and accidents on the job. If you notice a tool in some way is malfunctioning or broken, it should be properly noted. That way someone else doesn’t try to use it and get hurt. Hand tools that need inspection and how to do it are listed below.

SCREWDRIVER

It may seem like it is impossible to get hurt using a screwdriver, however this is very untrue. There have been many instances of people getting hurt using this tool. The most common ways for injuries to occur are when screwdrivers are being used improperly and not for their intended use.

Some things to check for:

• Handle is not hipped

• Handle is not broken

• Check the head for damage

• Check if the head is worn down

If any of these things are occurring with it, you should replace your screwdriver with a new one. Using one with any of these problems could lead to an injury.

CHISEL

A chisel is commonly used for many reasons when it comes to projects and construction. With any tool, over time chisels begin to break down and wear out from repetitive use. A common problem that presents itself with a chisel is that it will begin to "mushroom," or become so deformed with use that the head spreads and resembles a mushroom.

It is important to stop using it at that point and repair it. If you cannot repair the chisel you should replace it. Ensuring that you are using tools in the safest way possible can help to eliminate injuries.

WRENCH

When you are using a wrench, you need it to properly hold on to the bolt that you are tightening. If that can not be done it can slip and cause you to hurt yourself or do damage to what you are working on.

You can properly inspect the wrench and check for damage or malfunctions before use to prevent this from happening.

• Make sure it isn’t bent anywhere

• Check for chips

• Check for broken parts

• Replace it when it is worn out

HAMMER

Hammers are probably one of the most commonly used tools on a construction site and in the home. It is important to always inspect your hammer before you begin hammering to avoid an accident from happening.

Some things that you should check are:

• Make sure the handle isn’t chipped, broken, or loose

• Never use a hammer that has been taped back together

• Check that the claw of the hammer is in tact

If any of these things are wrong with your hammer, it is best to replace the hammer to be safe.

Five Hand Tool Safety Tips for Every Workplace

Hand tool safety tips are useful in every workplace. Almost every job calls for their use, and healthy hands are necessary for every job.

People who work in warehouses, construction sites, or in industrial workplaces will likely use hand tools more frequently, but even office workers use scissors, box cutters, and utility knives.

It’s actually in these seemingly “safe” workplaces, like offices, that focusing on safety is most important to emphasize: complacency and lack of awareness are top causes of injury. Also, workers who use tools infrequently are less likely to know how to use them properly. It’s easy to get out of practice regarding the safe use of tools.

For jobs that feature fewer regular hazards, tools and equipment safety rules don’t need to be addressed constantly. But having a quick bi-weekly safety moment will help remind workers to be mindful.

Cutting tools pose the risks of cuts, lacerations, and punctures. These five hand tool safety rules will help keep all workers safe.

1: Reserve a Specific Area Where Workers Use Hand Tools

If possible, have a designated space where your workers use hand tools, especially cutting tools. The physical act of having to go to a specific area to use tools will help workers to be more mindful of the task at hand. Other workers or visitors will also be aware that this is a zone where people are using potentially dangerous tools. It’s an area where they need to be vigilant about safety.

This is also a great way to stay organized. Everything having to do with tool use—PPE, tools, cutting mats, and so on—is in one place. Workers don’t have to search to find what they need. This also increases the chances of workers using proper PPE and sanctioned tools. The easier it is to stay safe, the greater the chance that workers will fully comply with all protocols. Having a specific designated area for tools will also make inventory easier to track. If something is missing, it will be obvious.

2: Keep PPE and Hand Tools in Good Working Order

The safe use of hand tools starts with tools that work well. For cutting tools, that means that the blade needs to be in working order. Dull blades are dangerous because they require more force to make the cut. This increases the possibility of the tool slipping.

Blades should also be clean, free of large chips, and, if they’re metal, free of rust. Note that when a standard (ie. non-Slice) metal or ceramic blade does need to replaced, the used blade must be disposed of in a sharps container. The tool itself should have no loose parts or cracks. Any tool that doesn’t meet these standards should be fixed or replaced.

All tools need to be cleaned regularly. This is especially true of tool handles. Hands are notorious for spreading germs. Items, like handles, that we touch become home to thousands of potentially infectious bacteria and viruses. This is one of the hidden workplace hazards that’s easy to overlook. Tools should be cleaned after each use.

3: Provide Appropriate PPE

All PPE should be free of holes or tears.

Also very important: PPE needs to fit well. A major complaint, especially about gloves, is that they are awkward and don’t allow free movement. PPE is never a one-size-fits-all proposition. Providing the appropriate gloves is critical, since lack of hand protection is a major cause of injuries.

PPE should be cleaned regularly, especially if several workers are sharing the same PPE. The same reasons that apply to cleaning tools apply here: it’s just good hygiene.

4: Choose the Safest Tools

Quality tools last longer and are safer than flimsy, cheap models. Your workers’ well-being is worth the investment. Look for tools that feature an ergonomic design. This will reduce fatigue and the possibility of repetitive stress injuries. Make sure the handle surface is easy to grip; this will reduce the chances of slippage.

Also look for other design features like whether the tool is properly weighted so it’s easy to control.

When choosing cutting tools, note how the user will be protected from the blade. Is there a safety cap? Is the handle retractable? Also consider blades that are safe to the touch (we’ll make that one easy: Slice is the only cutting tool manufacturer with a finger-friendly® blade).

5: Regularly Teach Proper Hand Tool Safety

Improper use is one of the most common reasons workers get injured when using tools. In your designated tool use area, post hand tool safety pictures and posters that depict proper use.

There are also loads of videos that show proper cutting techniques, like this one about using a box cutter safely

Additionally, provide hands-on demos, so workers see and experience how to use tools safely. Be sure to be methodical in your approach. A sample demonstration might include the following:

• Make sure your workspace is free of clutter

• Put on appropriate PPE; for hand tools this usually means wearing gloves

• Check that your tool is in good working order

Be mindful of using proper technique when using your hand tool

Make sure that any unsafe surfaces such as blades are covered or stored away once the work is done

Clean your tool with an antibacterial wipe

Replace your tool and PPE to its designated place

It’s Easy to Stay Safe

Safety isn’t complicated, but it must be taken seriously to avoid injuries. Unfortunately, it’s obvious—given the number of preventable workplace injuries employees suffer—that this isn’t always the case. Simple precautions like these five hand tool safety tips can be the difference between healthy hands and a trip to the emergency room.

Hand tools are such a common part of our lives but they can also be dangerous if misused incorrectly.

Reduce the chance of an accident by following the below safety measures.

1. Inspect regularly. Regularly inspect your tools to make sure that they are in good condition.

Common Precautions for Hands-On Projects

Safety first! Whenever taking on a project that involves manual labor, there’s always an inherent risk of bodily harm. Here are a few simple steps you can take to protect yourself.

1. Use insulated tools – This is of utmost importance if you’re going to be working with or near electricity. Insulated tools have rubber handles that protect from electric shock and provide easier grip. Not sure if your tools are insulated? Then assume they aren’t! If they are, they will have the universal “1,000 Volts” symbol on the handle, so check before you begin.

2. Hammers aren’t screwdrivers – Use each tool how it’s meant to be used. Don’t cut corners by using a wrench handle as a hammer or using a screwdriver as a pry bar. Improperly using tools like this is not only dangerous, but it’s also bad for the durability of your tools.

3. Always wear safety gear – When taking on a project, always wear safety glasses. If you’re doing heavy lifting, consider a lifting belt and gloves. Assess each step of your project and anticipate the necessary safety equipment before you begin.

4. Proper maintenance – Ensure that your tools are sturdy and in working order before you begin. You may think a sharp saw or knife sounds more dangerous than a dull one, but dull blades actually cause more accidents because of their propensity to slip.

How To Use Common Household Tools

1. Hammer – When using a hammer, the further back you hold the handle, the more force you’ll put on the object. So, if you’re hammering a nail, start with precise, lighter hits while gripping the handle close to the hammer’s head. Once the nail is in place, drive it in by gripping the hammer at the handle’s end. Swing from the wrist for control and from the elbow for power. The material you’re working with may require a different type of hammer/mallet.

2. Screwdriver – First, make sure you have the correct type of head and size that matches the screws you’re working with – phillips, flat, torque, etc. Grip the handle with one hand and grip the tip of the screwdriver, near the screw, with the other. Apply force and twist until the screw catches a grip, then ensure it goes in straight.

3. Stepladder – Never set up a stepladder on uneven ground. Always ensure the hinged metal braces are completely straight and locked in. Heed the printed warning on the stepladder to not step higher than recommended! Standing higher than that point increases the odds that you will topple. Do not leave tools on the ladder. The last thing anyone needs is a heavy wrench falling onto their head.

4. Hand Saws – First, make sure the saw is sharpened, the blade is straight and has the proper amount of tension. This will make your life easier and your work cleaner. Before you start hacking away, be sure to measure (check it twice!) and draw a pencil line on the place you’re going to cut. Make one soft, perfectly straight cut along the line, hold your elbows in by your side and angle the saw properly. Then proceed to slowly saw all the way through along the cut you’ve just made.

The hazards involved with hand tools may be overlooked, but they are commonly used and can cause serious injury. Don’t miss tips on safety and selecting the best tool in our blog, “Working Safely with Hand Tools.”

Electronic tools and equipment are the first requirements for any project undertaken. A selection of these tools is quite a tricky task but maintaining and storing them carefully so that these tools can last longer is not at all easy. Prevention is the systematic way of the protection of tools and equipment in order to keep them in a safe, usable condition, limit downtime and extend productivity. Maintaining these tools does not only make work smooth but also prevent workers from hazardous situations. Hence, it is necessary to understand ways for tools maintenance to ensure that these tools work properly and prevent users from electrical risks. For better understanding, check the points mentioned below:

CLEANING OF HAND TOOLS

The most basic category of tools used in the electronic industry is hand tools. Some hand tools that are frequently used are pliers, wrenches, screwdrivers, utility knife, hacksaw, wire strippers, and many more.

The most simple and effective way to clean hand tools is to wipe them with a clean piece of cloth at the end of the job. Don’t be afraid to wash them. If the hand tools are too dirty, wash them with soapy water to wipe away the grime. Remember to dry these tools to avoid rusting and corrosion.

To maintain wooden handles of hand tools, it is required to wipe them with a piece of cloth dampened in linseed oil. It will be helpful in keeping the handle clean and sturdy for a longer time.

CLEANING POWER TOOLS

When it comes to power tools, cleaning and maintenance can be a tricky task. Before cleaning the power tools, make sure that these are switched off and unplugged. Wipe all the dust off with a cloth piece or a brush. Use machine oil to lubricate the moving parts of the tools to keep them in good working condition.

KEEP THE TOOLBOX CLEAN

Along with keeping the tools clean, it is also important to take care of your toolbox and to clean regularly. Empty the toolbox and wipe it off with a clean cloth. If you use leather bags, make sure to do leather conditioning.

OILING ELECTRONIC TOOLS

The tools that have a cutting surface are necessary to be lightly oiled to prevent rust. Also, examine these tools and their surfaces to make sure they are in good condition.

STORING TOOLS SAFELY

If you don’t store tools properly, there is no use of cleaning them. For a big collection of tools, a metal cabinet could be a good option. After using these tools, store them in a sorted and organized manner. This way would not only help you to access them quickly but also keep them safe.

Electronic tools should not rub against each other when stored. Keep all the tools in the dry area and protect them from moisture, dust, and direct sunlight. To prevent injuries, keep the sharpen tool in a tool holder.

INSPECT AND REPAIR TOOLS

It is recommended to keep checking your tools at regular intervals. If there is any damage, repair them or replace them.

1. CRACKED OR LOOSE HANDLES:

Damaged wooden handle is prone to break while in use causing injuries. Hence,, it is required to replace them. However, if the handle is not partially damaged, sand it down. Sand till it gets smooth enough for further use. Finish the process by coating it with linseed oil.

2. MUSHROOMED HEADS ON WEDGES AND CHISELS:

Mushroom head implies that the striking edge has become malformed through use. In this situation, the head of the tool can shatter on impact. To solve this problem, keep it sharpened. Do it in every six months for better results.

These are some tips to maintain and clean your electronic tools. Frequent inspection can help in maintaining them

5 Tips to Properly Maintain Your Tools

Learning how to maintain your tools is a vital protective measure at your worksite.

You should always keep your tools clean, dry, and organized. Improper care can lead to decreased efficiency, diminished quality of work, and a host of other consequences that ultimately result in lost revenue.

1. Find Proper Storage

A well-organized and maintained tool storage system is a must. It will keep your tools in good condition and make them easy to find, but it can also add to your work area’s overall appearance and organization.

Invest in quality storage containers and organizers. This investment will help you keep your work tools sorted and easy to find.

Keep your work tools in an accessible place. When you need to use them, you won’t have to go on a mystery hunt and waste time searching for them.

When storing your tools, always keep them off the floor. There are several tool storage system options: bags, drawers, chests, and pegboards.

A helpful way to store small tools is with a shelf. You could also consider hanging up a pegboard. These are perfect for hanging tools like a lineman socket wrench, tight fit wrench, or adjustable angle wrench. That way, your tools are easier to locate and access.

If you’re able to, store your power tools in their designated case or original packaging. You can also place silica gel packs in your toolboxes to capture excess moisture to avoid corrosion.

Anti-rust and corrosion liners are the best way to protect your tools if you decide to use tool chests. Add them to your drawers or tool chests for enhanced protection. You can also store power tools safely in your garage with a pegboard.

2. Clean Your Tools

The best way to store your tools is to clean them after each use. If you don’t maintain your tools, they will accumulate dust, dirt, and grease. Also, they won’t be as effective when you need to use them the next time.

Ensure that your tools are free of grease and oil before storing them. It helps maintain their condition and prolong their lifespan.

Hand Tools

Clean them as soon as possible: the longer dirt stays on, the harder it is to clean. Start by removing any dirt collected during use with a brush or a cloth. Use a brush or other soft cleaning implement to get into all the tight spaces.

Next, use mild soap and water. Be sure not to use harsh chemicals, as they can be dangerous and make them unsafe to use.

Finally, maintain your tools by rinsing with clean water and drying off. Clean rusty industrial crank handles by brushing with a brush dipped in cleaning fluid. Afterward, you can wipe your tools with a dry cloth.

Power Tools

Unplug and disconnect power tools, vacuum off any dust that is easily accessible, then use compressed air to get rid of any dirt and debris in the vents. Clean rusted tools as soon as possible by using a stiff brush with light pressure, so you don’t scratch the metal’s surface.

Spray on a corrosion protector to decrease the rust rate of your tools. Clean all the knobs and gauges for everything to be in perfect condition.

Finally, make sure you inspect and lubricate any power tool parts that need lubrication.

3. Inspect Your Tools

No matter what trade or hobby you engage in, there’s one essential rule that you should never forget: inspect your tools after every use. It is especially essential for industrial crank handles, as even a tiny nick or dent can lead to disaster.

Do a quick visual inspection after each use – it doesn’t take very long. You need to take a minute or two to maintain your tools to prevent damage.

Check blades, cutting edges, and other pointed parts for any nicks or dents. If you find any damage, sharpen the damaged parts. Also, sharpen your tools at least every six months.

Check for loose nuts or bolts and fix them immediately to prevent further damage.

Try removing every sign of rust and corrosion, or replace the tool before use.

Inspect power tools for cracks on their handles and housing.

Examine the cords and plugs for any signs of damage. A damaged power cord can increase the risk of a fire hazard, so before using it, make sure to replace it with a safe power cord.

4. Monitor Your Environment

The best environment to keep your work tools in is a dry, clean, and organized space. This environment helps you find what you need when you need it, preserve your tools, and keep your work area looking professional.

Never store your tools in a hot or humid place, especially metal ones. Damp environments can corrode metals, and moist areas can degrade electrical components.

Meanwhile, a dry and cool place with a low humidity level helps maintain your tools for a long time. Keeping your tools in damp and stuffy garages or basements is not ideal. It can corrode metals, but there are also other issues related to dampness.

We recommend investing in a dehumidifier. Dehumidifiers are generally affordable and won’t make a dent in your budget when you consider the cost of your tools.

5. Practice Safety Precautions

Some of these tools can be dangerous to you and your coworkers. You should observe the following hand tool safety precautions:

• Wear the proper safety gear, including goggles, gloves, and a hard hat when using power tools.

• Make sure the tools are in perfect condition and have been well-maintained.

• Read the instructions carefully before using the tools.

• Keep bystanders, children, and pets away from the work area.

• Use caution when using lineman tools near electricity.

There are many reasons to maintain your tools, the most important of which is increased efficiency. For your tools to run smoothly and last longer, maintain them properly by using the tips mentioned above to clean, lubricate, inspect, and store them.
