Pliers are hand tools with a pair of pivoting metal arms and jaws used for gripping, bending, cutting, or twisting materials.

Common Types:

• Slip-Joint Pliers: Adjustable jaw opening for gripping different-sized objects.

• Needle-Nose Pliers: Long, thin jaws for precision work in tight spaces.

• Cutting Pliers (Diagonal Cutters): Designed for cutting wire or small metal pieces.

• Linesman Pliers: Heavier-duty pliers for gripping and cutting, often used by electricians.

Uses:

• Gripping small objects firmly.

• Bending or twisting wires.

• Cutting wires or small materials (with specific types).

• Holding components steady during assembly or repairs.

Vice grips, or locking pliers, are pliers with a locking mechanism that allows them to grip objects tightly without requiring constant pressure from the user.

Key Features:

• Adjustable tension via a screw mechanism in the handle.

• A release lever to unlock the grip.

Uses:

• Gripping objects securely while working on them (e.g., pipes, bolts, or nuts).

• Holding objects in place for tasks such as welding or drilling.

• Acting as a temporary clamp or wrench.

• Removing stripped screws or bolts.

Advantages:

• Provides a stronger and hands-free grip compared to regular pliers.

• Useful for tasks requiring high torque or force.

Channel locks (a brand name for tongue-and-groove pliers) are adjustable pliers with multiple grooves that allow the jaws to grip objects of various sizes.

Key Features:

• Longer handles for increased leverage.

• Offset jaws for gripping pipes, nuts, or irregular objects.

Uses:

• Gripping and turning pipes, nuts, and bolts.

• Plumbing tasks (e.g., tightening or loosening fittings).

• Handling larger or oddly shaped objects.

Advantages:

• Provides a wider jaw capacity than regular pliers.

• The grooved design prevents slipping during use.
