💡 What factors determine the lifespan of cobalt twist drill bits in heavy metalwork?
Most shop rats know that easing up on the trigger and slapping on some lube keeps cobalt edges from going soft too fast. These handy bits rip through tough alloys when you treat them right and pull out tired ones before they beat themselves up.
- Match spindle speeds to material thickness to prevent heat buildup and edge degradation
- Keep chips cleared with steady feed rates so the spiral flute design evacuates debris efficiently
- Store units in the included case away from humidity to stop oxidation on the shanks
