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.
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.
