The cutting happens inside the deep hole,chips discharge path is long,not easy to chips removal.3. The heat inside the cutting area is not easy to send out.4. Normally,the hole diameter-hole length ratio is big,when working,the drill bit is easy to vibrate and deviate. The following matters should be noticed during deep hole drilling process:1.
