Harper J. ★★★★★

Finally a compression bit that doesn't chatter on the plunge—ran it at 16k RPM through 3/4" ply and the top and bottom edges came out flawless. The Astra coating definitely helps it slide through without gumming up.

Owen ★★★★★

Cuts plywood edges so clean I barely touched them with sandpaper, and the 1 inch length of cut handles 3/4 stock in one pass without any burning. Ran it at 16,000 rpm like the specs said and the finish on both faces is basically flawless.

Julian P. ★★★★★

The AstraHP coating really holds up — after a full day of routing oak I checked the edge and it still felt sharp. Chip evacuation was clean with barely any fuzz on the top and bottom edges of my plywood cuts.
