How to Use Cobalt Drill Bits? 1. Ensure the left and right cutting edges of the drill are symmetrical when drilling. 2. Observe the uniformity of the spark while drilling, adjust the pressure in time, and pay attention to the cooling of the bit. 3. Mini HSS Cobalt Jobber Drill Bits can NOT be used in the impact drill. 4. Please use with cooling liquid to prolong the working life of the drill bits and to avoid overheating and breakage. 5.
