Steven ★★★★★

Cut a clean square pocket in oak plywood without any tear-out, and the center-cutting tip plunged straight in with zero chatter. The 1/8″ shank held tight in my router collet through the whole run.

Jason E. ★★★★★

I was worried the AstraHP coating would be just hype, but this bit cut through hardwood with no burning and barely any dust. The center-cutting plunge feature saved me from having to pre-drill holes for pocket cuts.

Mia S. ★★★★★

Took this bit straight to a piece of 1/2" hard maple for a plunge test, and the AstraHP coating really helped it glide through without any burning. The square end leaves a perfectly flat bottom in the pockets I've cut.
