Plus shaft


Two round grooves for axial fixation and two wedge grooves for an optimal torque transferring. Suitable for electric hammers up to 5Kg.



No hooking in and running off center


The symmetrical 4 x 90° cutting edge geometry prevents the hooking in or running off center of the drill bit when striking reinforcement or hard pebbles in concrete.



20% bigger carbide shoulder


Higher impact resistance and more aggressive drilling.



4 cutter geometry with centering tip


For deep and stable centering in a one-step, quick operation.



4 flute design


Fast dust removal for higher drilling speed, no clogging and less wear.



Bigger dust extraction area


Less wear and longer lifetime.



Optimum guidance in drilled hole


Thanks to the drill bit's four cutting edges and four-spiral geometry, it is optimally guided into the drilled hole. You get perfectly cylindrical drilled holes which are optimum for use with anchors.

Notice

*Iron reinforcements may only be drilled through with permission from structural engineer.
