💡 How do you choose and use M35 cobalt drill bits for drilling hard metals and wood?

A handy guide to maximize bit life and performance.

- Use slow to moderate speeds with steady, light pressure to limit heat generation - Use cutting oil or light lubricant when drilling metals to prolong bit life - Start with a pilot hole for precise centering and to prevent wandering - Regularly clear chips to maintain cooling and cutting efficiency
