Reciprocating Saw
By Victor Nifo

• Objectives
• Impart knowledge concerning reciprocating saw
• Describe function

2
Definitions

• Saw
• Tool for cutting
• Serrated blade
• Worked either by hand or other power
• Reciprocating Saw
• Straight blade mounted on gun-like body
• Blade moves back and forth
• Similar to jigsaw- more powerful

3
Additional Information

• Cut through virtually anything
• Rough cuts
• Models range in power, speed, and features
• Industry standard Milwaukee Sawzall
• Reciprocating saw generally called a "Sawzall"

4
How It Works

• Battery connected to motor
• Movement created by gears
• Bearing allows arm to rotate with gear
• Other end of arm connected to milled component
• Arm is free to pivot, causing milled component to
  move back and forth
• Motion causes teeth of blade to cut material

5
Additional Notes

• Counterweight
• Present on larger gear
• Allows balanced motion of blade
• Case
• Encloses gears and arm
• Prevents
• Grease leakage
• Particles affecting motion of gears

6
Additional Notes

• Speed Holes
• Located opposite to counterweight
• Reduce mass to ensure balanced rotation

7
Conclusion

• Definition
• "Reciprocating saw" because the blade moves back
  and forth
• Acts like a jigsaw, but more powerful and
  versatile
• Function
• Gears and pivoted arm allow the back and forth
  motion of the blade
