The Challenge

The customer manufactures large automotive molds made from P20 (28-32 Rc) using a Schienke tri-spindle deep hole drilling machine with canola base soluble oil coolant at 280 PSI (19 bar).

The operation was not cost effective due to inconsistent tool life and very low penetration rates. The customer needed an improved solution.

The shop supervisor was so impressed, he stated, “At this point their performance (BT-A) outweighs the cost. Just get them here if you can.” The BT-A made a huge difference for this customer.
