Review on Optimized Kempston Keyhole Cutter - 501011, Enhanced Cutting Diameter by Jeffrey Mosqueda

Revainrating 4 out of 5

You can easily burn if your pitch and speed are right and when.

Nice part. I have now bought two of these. They work fine on my CNC router. They can burn easily if your feeds and speeds are correct, and if they become blunt they have a very difficult time penetrating the material.

Pros
  • Anti-kickback design
Cons
  • I will add later
