Production Description
1. Flute Design: Twist drill bits have two or more flutes that spiral around the body from the tip to the shank. The flutes serve multiple functions:
2. Chip Removal: As the bit rotates, the flutes help to lift and evacuate the chips or debris from the hole, preventing clogging and overheating of the bit.
3. Coolant Delivery: In some twist drill bits, especially those used for metalworking, the flutes may have channels for coolant or cutting fluid to be delivered to the cutting edges. This helps to lubricate and cool the bit, reducing friction and heat buildup.
