Kennametal introduces the optimised BF combination drilling system.

The new BF HP system with through coolant offers cost savings through: * Combining centering, drilling, chamfering and countersinking into a single operation.

* Flexibility to change axial drilling depths as well as chamfer angles and spot face options with stock standard indexable inserts and drills.

* Creating special countersinking profiles using custom inserts.

* Lowering total tool inventory costs by eliminating expensive special drills.

All components are stocked standards and available to order without minimum order quantity.

The BF HP system with advanced PVD multilayer-coated grade KC7315 drills and inserts is designed for machining all steels, including alloy and tool steels, and all irons.

The BF HP system is highly adaptable to market segments such as fluid power, automotive and general engineering.

The stock standard drill diameter ranges from 3.175mm to 18.00mm in 3xD lengths.
