Impart knowledge concerning reciprocating saw By: Victor Nifo Objectives: Impart knowledge concerning reciprocating saw Describe function Reciprocating Saw Reciprocating Saw

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 Reciprocating Saw Reciprocating Saw

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" Reciprocating Saw

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 Reciprocating Saw

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 Reciprocating Saw

Additional Notes Speed Holes Located opposite to counterweight Reduce mass to ensure balanced rotation Reciprocating Saw

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 Reciprocating Saw
