H-DRILL is designed for improved drilling stability because of the optimized cutting edges that generate low cutting force and excellent self-centering capability for higher accuracy holes. The drill’s wide chip gullet with polished flute enables smooth chip evacuation. Its multi-layered coating technology gives maximized toughness as well as increased wear resistance while prolonging tool life through high efficiency machining.
New NHD-K type drills are designed to minimize chipping or damage to the cutting edge that may occur when machining cast iron. The NHD-K type drills are optimized for cast iron machining because of its unique multi-angle cutting edge geometry for maximized edge strength and a cutting edge that evenly distributes the machining load across the cutting edge. The solid carbide drills minimize burrs to produce an excellent surface finish during operation.
