Beta 416G/SP25 HSS Stepped Geometry Bit Set of 25

Higher cutting accuracy: The peculiar stepped geometry of the tips facilitates the creation of extremely precise holes in size and perfectly circular in shape. It also allows you to widen existing holes. Higher cutting speed: The special stepped geometry (present from Ø 3 mm) allows a higher penetration speed, up to 50% more than a conventional tip. Increased stability: The stepped tip facilitates better initial centering and gives greater stability to the drilling. LONGER DURABILITY: The superior quality of HSS steel gives the drill a prolonged life for drilling alloyed and highly alloy steels, steel, iron, aluminium and metals. Perfect grip: The shank with 3 flat grooves (from Ø 3.5 mm) ensures a perfect grip of the chuck jaws avoiding slippage and transmits power at best.
