💡 How should you prepare a carbide end mill for heavy duty CNC router performance?

You get steady cuts and extended tool life by keeping your shop routine handy and focused.
- Tuck the straight shank completely into the collet before locking it down tight
- Pick spindle speeds that match your metal thickness to keep chips moving upward
- Trust the black DLC finish to cut friction and stop epoxy bits from clumping
- Adjust feed rates slowly during deep slots to maintain control and reduce vibration
