Dust-free drilling
- The dust is extracted from the drill hole as soon as it is created
- Protects the user from health risks
- Extends service life
- No subsequent borehole cleaning necessary
- Significantly inhibits the formation of dust on the construction site
Very good compatibility with reinforcements
The symmetrical 4 x 90° cutting edge geometry and the patented reinforcement chamfers prevent the drill bit from hooking in or running off centre when striking e.g. reinforcements.
Perfect drilling properties over the entire service life
One-piece tungsten carbide element for high stability thanks to the maximised attachment surface with the steel body.
Bayonet-click connection
Quick and easy drill change from the suction unit.
Drill depth indicator
Adapted to the drill diameter. For plastic anchors.
Precise drilling
The special self-centring tip enables precise tapping.
- Use only possible in conjunction with suction unit art. 0648 040 000.
- Only for use with dust class M vacuums.
- Iron reinforcements may only be drilled through with permission from a structural engineer.
