Overview

A cut-off saw — also called a power cutter or concrete saw — is a handheld saw that spins a large abrasive or diamond wheel. It cuts concrete, block, pavers, stone, pipe and steel.

The unit pictured is a cordless (battery) power cutter, so there are no fumes or fuel to deal with.

It's the go-to tool for quick straight cuts in hard materials on site, from kerbs and pavers to ductile pipe.

Safety

  • Never cut with the upper front quarter of the blade — that's the kickback zone.
  • Stand to the side of the cutting line, never directly behind the blade.
  • Wear a respirator, eye and face protection, and hearing protection.

For battery / electric

  • Charge in a ventilated area away from flammable materials.
  • Keep emergency stops unobstructed and test them before use.
