Victoria Q. ★★★★★

I've been using this as a replacement for my jig, and the 1-inch cut length gives me just enough depth for precise through-dadoes without any binding. The Astra coating seems to help the bit run cooler on longer passes, which is a nice bonus.

Scarlett ★★★★★

The Astra coating on this bit made the cut noticeably smoother through the hardwood I was routing for drawer slots. It fit perfectly into my jig without any wobble, exactly matching the dimensions stated. Saved me from buying a whole new jig assembly.

Joshua V. ★★★★★

I was skeptical about the coating making a difference, but this bit cut through my oak with noticeably less burning than my old carbide ones. The 1-inch length of cut was perfect for the dado slots I needed for shelving.
