💡 What is the best way to use cobalt M42 twist drill bits for stainless steel and hard metals?
Cobalt M42 bits excel in high heat and tough materials when used with the right speed and lubrication.
- Use correct speed and feed to prevent overheating during stainless steel drilling
- Keep bits sharp and use coolant or lubrication to reduce wear and chip buildup
- Start with a pilot hole for accurate guidance on hard metals
- Drill perpendicular to the workpiece to prevent wandering and ensure straight holes
