Customer Reviews (4.8 / 5 · 5 reviews)

Robert ★★★★★

The cobalt twist held up through a full afternoon of stainless steel without losing its edge—way better than the cheap bits I’d been burning through. That red helix design really does clear the shavings faster.

Chloe Z. ★★★★★

Just drilled through an old car's hardened brake rotor and it didn’t even slow down. The cobalt edge held its bite the whole way through, no smoking or glazing like my last cheap bits. A bit pricey, but worth it for the time saved.

Riley ★★★★★

Took this to some hardened steel that chewed up my last few bits, and the cobalt edge held its bite through the whole job. The red helix design seems to clear chips better than a standard twist, which kept things from binding up halfway through. Definitely the best $8 I've spent on a 1/2-inch bit in
