The Challenge

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 T-A GEN2 eliminated the poor chip formation while significantly reducing the cost per hole.

Objective: Better chip formation
Industry: Structural steel/ fabricator
Part: Plate
Material: 44W structural steel
Hole Ø: 0.813" (206.502mm)
Hole Depth: 4.000" (101.600mm)
