D-MAX

Dustless bit with automatic drill hole cleaning

The D-MAX dustless bit from the DustCon series is the ideal solution for clean, fast drilling with high durability for larger hole diameters and work safety while drilling. Proper cleaning of the drilled hole also no longer requires the use of brushes and a blow-out device. The dustless bit reliably takes care of these work processes while drilling, as stone dust is suctioned right when it is created. The robust head geometry with active air cooling also allows for a long lifetime.

ZENTRO MAX FL

2-fluted rotary hammer drill bit with optimized head design

The ZENTRO MAX FL combines rapid drilling progress, especially for deep holes, with a robust drill bit. This is achieved thanks to a head geometry coordinated to the drilling diameter with 2 or 4 cutting teeth. The drilling dust is removed faster as a result. This sets the stage for rapid drilling progress.

The patented Multi-Value-FluteTM results in a long-lasting drill bit and creates plenty of room for the drilling dust thanks to its 2-fluted design.

Applications
  • Extra-long drill bit for renovation and sealing in masonry and concrete
  • Drilled holes for subsequent reinforcement connection
  • Conduit hole drilling in concrete and masonry
Building materials
  • Concrete , Brick , Masonry , Natural stone
Characteristics
