The Challenge

The customer is a mold maker for the plastics industry that contacted Allied to test BTA tooling. The workpiece is a 21” (533.4 mm) thick test block made of P20 material (28-32 Rc). They are using a Schienke Gundrill machine with Hulcut 745D semi-synthetic coolant (10% concentrate) at 1000 PSI (69 bar).

The customer needed to decrease total hole costs and improve the tool life.

The BT-A Drill successfully decreased total hole costs while improving the tool life.
