DIA 200 HWS diamond core drill


The drill feed is generated by turning the handwheel. Improved drilling behaviour through reinforcements is possible thanks to the spring decoupling.


The robust fastening holder ensures that the feed rod is securely fixed to the ground. The fastening holder is drilled over by the core bit. There is no damage to the ground outside the borehole.

XIP soft impact

The switchable DUSS XIP soft impact (X-tra Impact Power) allows the avoidance of water when core drilling into hard materials such as concrete.


The torque that occurs during drilling is compensated for by the corresponding surfaces of the torque sleeve and the feed rod screwed to the substrate.

Highly efficient dry drilling with dust extraction

Thanks to the perfectly balanced system of machine and diamond core bits, the efficient removal of drill dust is guaranteed.

Appications & Features



  • Dry diamond core drilling with dust extraction in concrete and reinforced concrete with soft impact, in highly compacted sand-lime brick and masonry
  • Dry drillings in water sensitive areas like server rooms, electrical installations, archives or production sites
  • Retrofitting of plumbing and heating systems, electrical installations in inhabited rooms
  • Drilling for house connections from the inside and outside, also in insulated walls
  • Drilling in confined, hard-to-reach places, e.g. with existing pipe installations, structural conditions such as ceiling projection or window lintel
  • Drilling where the surroundings of the drilling site must not be damaged, e.g. by anchor holes
  • Hand-held drillings or drillings with drill stand are also possible
  • Building constructions, restorations, sanitary, heating and air-conditioning technology and drilling services


* only in conjunction with optional WDFH rotary water union


  • Mountable feed system CLF for uncomplicated, effortless drilling, combining the advantages of hand-held and stand-guided drilling
  • Continuous feed rod in the machine replaces the guiding function of a drill stand
  • Manual feed enables effortless drilling and absorption of the torque and the machine weight during drilling
  • Integrated drill core catcher, drill core remains reliably on the feed rod and can be easily removed
  • Switchable soft impact (XIP) for accelerated drilling progress
  • Lower set up and time effort as when drilling wet Nassbohrungen in concrete or reinforced concrete
  • Clean working environment where time-consuming cleaning is no longer necessary
  • Optional wet drilling with WDFH rotary water union

  • Handle arrangements and machine positions are variable for ergonomic work
  • LED display for performance monitoring and service planning
  • Trigger lock for continuous operation can be easily operated even with working gloves
  • Ultra-efficient dust extraction
  • Efficient removal of drill dust guarantees a reliable drilling performance
  • Safety clutch with anti-lockup system
  • Screw-in auxiliary handle for non-fatiguing, back-saving posture when drilling downwards, hand-held
  • Electronic overload protection and soft start

Drilling with feed

  • Feed system CLF

    The unique DUSS CLF (Centre Line Force) feed system combines the advantages of hand-held drilling with the convenience of stand guided drilling.

  • Energy-saving work

    The lightweight drilling unit can be used universally and, thanks to the manual feed integrated into the machine, enables energy-saving work.

  • Feed rod in hollow guide rod

    The force is applied centrally in the drilling axis by the continuous feed rod in the guide rod.

  • Secure work

    The feed rod compensates the torque, ensures a securely guided, centred drill hole and holds the drill core.
