Customer Reviews (4.6 / 5 · 5 reviews)

Penelope ★★★★★

Used it to cut through 1/4" steel plate for a custom bracket, and the bi-metal teeth held up without any sign of wear. Clean, fast cuts even under heavy pressure. Definitely worth the price for a made-in-USA tool.

Charlotte ★★★★★

Cut through a steel door frame like butter—this 4-inch bi-metal holesaw stayed sharp the whole time and left a clean edge. I've used cheaper ones that'd bind up, but the made-in-USA craftsmanship really shows in the cut quality.

Benjamin ★★★★★

The bi-metal teeth on this 4-inch holesaw chewed through a stack of old plywood without dulling. The 102mm size is exactly what I needed for running new cable, and it's holding up well. A solid, precise cut every time.
