Ava P. ★★★★★

Finally a 1/8″ bit that actually clears chips without me having to clear the path manually every few seconds. The AstraHP coating seems to be holding up well after a dozen passes through hardwood.

Adam ★★★★★

I was surprised how cleanly this bit cut through hard plywood without any burning on the edges, even at higher feed rates. The chip evacuation is noticeably better than the solid carbide bits I've tried before.

William W. ★★★★★

The AstraHP coating held up through a dozen cuts in plywood without any burn marks, and the up-cut spiral pulled chips out cleanly the whole time. The O-flute design really does keep the slot clear, which made a big difference on my last job.
