The customer is drilling solid steel plates made of 44W structural steel. They are using a Daewoo 4020 D 20HP Vertical Machining Center with 300 PSI (20.684 Bar) through tool coolant.
The customer requested a tool that could break the chip, as they were getting ‘bird nests’ around the spindle every time.
The GEN2 T-A eliminated the poor chip formation while significantly reducing the cost per hole.
