The Challenge

The customer makes spacers for torque converters made from 1045 using a CNC lathe IKEGAI-Fx 25N with external coolant.

Because the Kennametal tool was expensive and had lengthy lead times, the customer asked Allied for a solution that would also improve cycle times and lower the cost per hole.

The Revolution Drill® met the customer’s needs and provided twice as many drilled holes in half the time.
