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.
