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.
