Solid carbide drill for both wet and dry, steel and cast iron

The B222HP solid carbide drill has been specifically designed for both wet and dry machining applications at drilling depths of 5 times diameter. It is designed for application in both steel and cast irons and complements the short version B221HP range of drills. The drill has the patented Kennametal HP point geometry allowing high penetration rates and increased productivity. Productivity gains of up to and beyond 30 per cent can be achieved, increasing throughput and reducing manufacturing costs. It is supplied in the Kennametal grade KC7315 which has a smooth multi layer TiAIN coating. This smooth coating reduces built up edge and also promotes free flow of the chips away from the component. It also ensures long predictable tool life even in the most demanding operations. Such operating parameters are normally only associated with through coolant drills. The drill can be applied in many applications and can be used to rationalise and reduce inventory and its associated costs. The high metal removal rates and ability to run dry can significantly impact in costs associated with cutting fluids and subsequent cleaning of components. The B222HP in KC7315 is available from stock in cutting diameters from 3.0 – 19.05 mm with a form A cylindrical shank.
