  1. Reciprocating Saws Objective: Provide a general understanding of reciprocating saws and their use. By: Derek Landschoot References: http://www.workbenchmagazine.com/main/recip-saw.html http://www.mkmorse.com/jigg.html http://www.dewalt.com/us/articles/article_cordless.asp?Site=cordless&ID=170 http://www.ridgid.com/Manuals/5228Manual.pdf

  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.
