I. There are two types of Saber Saws, Sawzalls, & Jigsaws
II. Sawzall – A type of all-purpose saw that operates with a back and forth motion. Since it is able to cut wood, plastic, metal and many other materials, this saw is commonly used in demolition or remodeling work.
a. types of blades – The more teeth per inch(TPI) that a blade has, the smoother the cut will be
i. Wood Cutting – Used for cutting wood usually has 6-8 TPI.
ii. Metal Cutting – Used for cutting metal usually has 14-18 TPI.
iii. Bi-Metal Cutting – Used for cutting wood or metal, especially wood embedded with nails. Usually has 9-13 TPI
III. Jigsaws This saw is similar to a band saw, the difference is that it is portable. Its portability makes it a great tool to have on the jobsite for cutting irregular shapes or finishing cuts made with a circular saw. A Jigsaw can cut plywood and other, larger framing members.
IV. Safety Rules – Safety Rules for all saber saws are the same.
a. Select the correct blade for the work and properly secure it in the chuck
b. Be certain that the material to be sawed is properly clamped
c. Keep the cutting pressure constant, do not force the cut
d. Allow the saw to come to a complete stop before setting the saw down
e. Hold the base securely on the work when cutting
V. Demonstrate the process of changing blades for both saws
VI. Allow class to enter the shop to practice changing blades
