Recommended Cutting Speeds
For cutting carbon steel pinions with high speed steel cutters:
- Cutter Diameter 14mm 430-500 rpm
- Cutter Diameter 20mm 300-350 rpm
- Cutter Diameter 24mm 250-290 rpm
- Cutter Diameter 26mm 230-270 rpm
for cutting brass a speed of up to 3000 - 4000 rpm can be used but a much lower speed will preserve the life of the cutter.
