Customer Reviews (4.6 / 5 · 5 reviews)

Daniel ★★★★★

I had some problems with chip evacuation on a previous bit, but this one's up-cut design really clears the channel beautifully when I'm cutting hardwood. The AstraHP coating shows no signs of wear after several test passes, and the finish is noticeably cleaner than what I'm used to.

Chloe ★★★★★

Cutting through 1/8″ plywood with this bit feels effortless, and the AstraHP coating really does resist gumming up after multiple passes. The up-cut design clears dust fast, so I'm not fighting with debris buildup mid-job.

Violet ★★★★★

The chip evacuation is noticeably better than with my old bits, and the AstraHP coating seems to handle heat really well. I’ve been running it through some dense hardwood, and it’s holding an edge far longer than I expected.
