2. The Basics Reciprocate: back and forth Straight Stroke and Orbital types –Orbital has more aggressive cutting action (not for use on metal). –Straight is more common and for general purpose use. –0-3200 strokes per minute –11 amp motor common Blade Types: General Purpose, Metal Cutting, Carbide Grit Number of teeth: less teeth/inch= more aggressive and rough cut 3-8 TPI for wood blades 12-18 TPI for metal cutters Carbide Grit: Used for dense or brittle materials such as ceramics. Tungsten alloy grains are bonded to the body of the blade, creating a smooth cutting edge that wont tear thin materials. Bi-Metal blades are common. Hard steel teeth are welded to a more flexible body.
