💡 What is the correct feed rate for operating a tungsten carbide hole saw on stainless steel?
Adjusting machine pressure extends cutter longevity effectively.
- Maintain steady downward force to prevent friction heat buildup during penetration
- Apply low torque settings initially to establish a true starting groove
- Increase speed gradually once the kerf is fully seated in the workpiece
