SDS PLUS Zentro 4 Cutter Drill Bits with Carbide Tip

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° symmetry, all four carbide cutting edges function evenly and do not seize up on hitting reinforcing steel. Centring tip for straight forward spot drilling with pinpoint accuracy. 

Penetrates through steel deck plate eg Bondek® and concrete in one easy process.
