The Complete Handbook of Reciprocating Saws

Chapter 1: Understanding Reciprocating Saws

A reciprocating saw is a handheld power tool that cuts by moving a blade back and forth in a linear motion, typically three to four thousand times per minute. The blade extends a fixed distance—usually between three-quarters of an inch and one and a quarter inches—with each forward and backward stroke. When you press it against a material, the blade teeth cut on both the push and pull strokes, removing material quickly and with less finesse than a circular saw or bandsaw would. It is, in essence, a powered version of a hand saw that does not require the user to move the saw back and forth; the machine does that automatically.

This simple mechanism—push, pull, push, pull—is what makes the reciprocating saw one of the most versatile cutting tools on any job site. It cuts through wood, metal, plastic, drywall, masonry, and composite materials with nothing more than a blade change. A plumber uses it to cut through copper and steel pipe inside walls. A carpenter uses it to trim door frames or cut rough openings in new construction. A demolition crew uses it to rip apart walls, cut studs, and separate salvageable materials. A rescue crew uses it to cut through vehicle frames and structural steel. Each job requires a different blade, but the same tool does them all. That flexibility, combined with low cost and high portability, is why reciprocating saws are found in so many tool bags and rental fleets.
