Alpha Sds Zentro Drill Bit 4 Cutter 8 X 110mm

Dynamic drilling ability with secondary cutters protecting the drill bit in the event of reinforcement collision
The one-piece, solid carbide tip and patented reinforcing chamfering ensure low vibration and optimum drilling performance when drilling into reinforcing steel
Thanks to optimum 4 x 90 Deg symmentry, all four carbide cutting edges function evenly and do not seize up on hitting reinforcing steel
Laterial support and maximum possible area of the interface between the carbide and steel body compensate fortorsional forces
Centring tip for straight forward spot drilling with pinpoint accuracy
