Specification

Strong hammer drill bit with X-shaped head geometry and four-spiral feed helix for fast drilling speed with significantly smoother running and greater precision in comparison with conventional drill bits featuring a head with two cutting edges

No hooking in

The drill bit tends to hook into reinforcements to a far lesser extent thanks to the geometry with four cutting edges.

Precise spot drilling

The special self-centring point enables precise spot drilling.

Greater precision

This is the result of the four cutting edges of the drill bit head being better positioned in the drill hole, as well as the four-spiral drill bit helix and the smaller friction surface. The four large-volume feed helixes ensure fast transport of drilling dust.

Notice

Please note: With long drill bit lengths, pre-drill with a short drill bit of the same diameter!

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