The Alpha ZENTRO Masonry range boasts 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.

Laterial support and maximum possible area of the interface between the carbide and steel body compensate for torsional forces

Centring tip for straight forward spot drilling with pinpoint accuracy

Four symmetrically functioning spiral ridges ensure low, uniform flute wear

Optimised flute core strength ensures low vibration drilling performance and exceptional fracture resistance

The high-volume flute geometry ensures the optimum removal of drilling dust

4 Cutter head prevents seizing when drilling through reinforcing steel

Penetrates through steel deck plate e.g. Bondek and concrete in one easy process
