How to Use Twist 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 twist drill bit 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. Drilling metal is recommended for use on bench drills. 6. Hand drills are suitable for drilling low hardness materials.Kindly Note: Please allow 1-2mm errors due to manual measurement, thank you for your understanding!
