Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

The coating on this bit really helps it glide through the wood without burning, which is a huge plus. I used it to cut keyhole slots for cabinet hanging and it left a clean, precise edge every time. Definitely a solid upgrade from my old uncoated bits.

Stella S. ★★★★★

I was pleasantly surprised by how smoothly this bit cuts through hardwood—the AstraHP coating really seems to reduce friction. The 3/8-inch diameter is perfect for clean keyhole slots without any burning.

Samuel X. ★★★★★

The slot comes out clean with no chatter, and the 3/8-inch cut is just wide enough for standard hanger screws. The coating seems to keep the bit from gumming up even after a dozen slots in pine.
