Indexable U Drills - Silver, Optimized Insert Position For Stable Drilling And Effective Chip Evacuation

U drills are used in CNC turning and VMC machines for hole-making operation at the highest feed rates with rectangular-shaped inserts that offer a soft starting cut and the highest stability.
Same insert is used in each pocket for reducing inventory costs.
Cutting force during drilling is balanced between the central insert and peripheral insert.
The relative position of each insert is optimized to provide stable drilling.
The chip evacuation direction can be controlled with the chip control groove at the center of the breaker, enabling good chip evacuation.
