Seals are required between the workpiece and the drill sleeve and at the rear of the chip box
The required coolant pressure is about 50% higher than the STS single pipe drill system
High coolant pressure and filtration accuracy of 5 - 10 µ m (0.000196 - 0.000394 inch) are required
Excellent performance in drilling very hard materials and chip breaking difficulties
Able to achieve fine tolerance and ideal surface quality
