Hammer Hohlbohrkrone Hollow Hammer Core Bit – With Innovation Toothed Crown!
For use in concrete, masonry and natural stone.

The Hollow Hammer Core Bits were redesigned as part of our permanent development process.

The roof-shaped guide teeth (1) ensure improved tool alignment
and increased rotational stability. The wedge shape is particularly
aggressive in collision with steel reinforcement.
The flat hammer teeth (2) are significantly more efficient in such a
prepared drilling base.
effect is supported by the asymmetrical teeth layout.
A performance increase exceeding 30% is achieved with this new design. The high hammer power of modern, heavy rotary hammer drills can be fully exploited.
The well proven characteristics remain:
hollow crown body with more efficient outer spiral for increased
durability and minimised friction losses
DC quality carbide and special brazing technique
large product range of one-piece and multi-piece tools

PGM tested drills:
they live up to their reputation!

Our masonry drill bits bear the mark of conformity of the Prüfgemeinschaft Mauerbohrer e.V. (PGM), which is granted only to selected manufacturers.


Drill bits with this mark are guaranteed to conform to strict criteria regarding the diameter
of the carbide tip, its symmetrical soldering, and the concentricity
of the drills.

Only PGM tested drill bits are used by anchor manufacturers and institutes for the development and approval tests of new anchors.

Insist on the PGM mark of conformity the next time you purchase a high quality drill bit. You can rely on it!
