This is a revolution in small-diameter deep hole drilling!

Drilled 360 holes without drill breakage.Processing time that used to take 4.5 hours at 45 seconds per hole, it has been reduced to 8 minutes at 1.3 seconds per hole, an amazing reduction in time!
Non-peck drilling by the coolant through spindle reduces processing time by 97%.
