These Type B center drills adopt premium cobalt-reinforced high-speed steel with hardened titanium coating and fully ground finish. Available in specifications from B1.5 to B6, they are purpose-built for stainless steel and hardened metals, compatible with drill presses and CNC equipment.
The cobalt-enhanced substrate and titanium coating deliver outstanding wear resistance and hardness for tough stainless steel and automotive spring steel machining. Precision-ground cutting edges ensure precise centering, clean burr-free holes and consistent dimensional accuracy.
Perfect for center spotting and pre-drilling positioning of various metal workpieces, they deliver remarkable durability even under heavy workloads. They extend service life significantly, cut tool replacement costs and effectively improve overall machining efficiency.
