Amelia ★★★★★

The AstraHP coating really makes a difference—this bit glides through plywood without any gumming up, even after multiple passes. It leaves a smooth, chip-free edge that saves me sanding time.

Violet ★★★★★

Finally got clean cuts on 1/4" ply without the tear-out I usually fight, and the down-cut design makes a huge difference on the top face. The AstraHP coating seems to keep the bit slick, so it hasn't gummed up even after a dozen crosscuts.

Ruby U. ★★★★★

I’ve been fighting chip-out on plywood dados for a while, and this bit’s down-cut design finally gave me super clean edges on 1/4″ material. The AstraHP coating is holding up well through several passes, so no gumming up yet.
