Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

My first cut on 1/8" steel felt like it went through butter, and the bi-metal teeth show zero wear after a dozen holes. The 146mm diameter is perfect for running conduit through studs, no pilot bit swapping mid-project.

Miles B. ★★★★★

Bored with changing blades mid-cut? This one chewed through my stack of 1/4" plates without slowing down, and the bi-metal teeth still look sharp. Built tough, and the 5-3/4" size handled exactly what I needed.

Elizabeth F. ★★★★★

Cut a clean 5-3/4" hole in 1/4" steel plate without the teeth chattering or grabbing once, and the bi-metal construction held up way better than my old cheap carbide set. Took a few passes with steady pressure but the finish was surprisingly smooth for a hole this size.
