Richard ★★★★★

First time running a compression bit on my CNC and the cut quality on both faces of the plywood was basically tear-out free. The 1/2 inch shank felt rock solid in the collet at higher feed rates too.

Carter ★★★★★

The AstraHP coating really does keep the cut cooler — after a dozen sheets of oak ply I saw almost no burn marks on the edges. Compression geometry gave me clean faces top and bottom, no tearout at all.

Natalie K. ★★★★★

Ran this on melamine-faced plywood all afternoon and both faces came out chip-free, no tearout at all. The 1/2 inch shank feels rock solid in the collet and the coating still looks new after a dozen sheets.
