Victoria Y. ★★★★★

Cut a clean 7/8” hole in a steel door frame without slowing down, and the teeth still look fresh after a half-dozen uses. The bi-metal construction is holding up exactly as promised, and the US-made quality shows in how true it runs. Just wish the arbor was included, but that’s on me for not reading

Alexander P. ★★★★★

The bi-metal construction made quick work of cutting through some old plywood, and the 7/8 size was just right for the holes I needed. The teeth held up well without any binding or chatter, making this a solid addition to my toolbox.

Harper T. ★★★★★

Cut through the drywall and even a few nails without the teeth dulling, and the bi-metal construction clearly holds up. Wished it came with the arbor included, but the cutting edge stays sharp after a solid day of use.
