Steven ★★★★★

Finally got a clean cut on some tricky melamine without any chipping—the down-cut spiral really does make a difference. The AstraHP coating seems to be holding up well so far after a dozen passes through plywood.

Adam Q. ★★★★★

I’ve put this bit through a full day of trimming oak and the AstraHP coating is still holding up with zero pitch buildup, which surprised me. The down-cut spiral kept the edges clean and chip-free even on the trickier end grain passes. It’s already earned its spot in my daily kit.

Miles P. ★★★★★

The down-cut spiral action left an edge so clean I didn’t even need to sand afterwards; the AstraHP coating seems to be holding up well after a dozen or so passes on hard maple. It’s a solid upgrade over the cheap bits I was burning through.
