  • In case of using external coolant system, chip evacuation will be bad. Therefore ap should be measured within 1.5 times (1.5 x DC) of drill diameter (DC).

: 1st recommendation : 2nd recommendation

1. Apply a sufficient amount of coolant.

2. If cutting speed is decreased too much from above condition, chip evacuation performance will deteriorate. A B

If the feed rate is increased too much from above condition, inner edge chip evacuation will deteriorate. If the feed rate is decreased too much from above condition, outer edge chip evacuation will deteriorate. 3. If chips are too long when low carbon steel drilling, increased the cutting speed to 120~150m/min. If this does not solve the problem, try step feeding.

[How to step feeding] 1. Cut 1~2 mm 2. Return 0.1 mm 3. Repeat 1. and 2.
