It’s happened to all of us.
You make a pass with your router, hoping for a clean edge — but your result is tearout and burning.
What gives?
The problem might not be your tool, or even your router technique (of course not).
The problem might be your straight edge bits — the long-time industry standard.
Spiral bits (the straight bit’s younger, better-looking cousin) cut faster, cleaner, and stay sharp longer than traditional bits.
They’re my go-to bits on the router and CNC for everything from shallow grooves, to full depth cuts, to edge-jointing and flush trimming.
We’ve partnered with Bits&Bits to release a line of Katz-Moses Tools Astra Coated Bits. These are my favorite bits — with an added Katz-Moses twist (dad-level pun intended).
So to celebrate the launch — and help you better understand them…
I’m going to explain how spiral bits work, why I prefer them over traditional straight bits, and how to get the best results with down-cut, up-cut, and compression bits.
