Art.-No. 546602
Top Features
  • Drilling and cleaning as one single step.
  • No conventional cleaning of anchorage needed (according to particular ETA approvals).
  • Secure and efficient setting of chemical and mechanical anchors.
  • Healthy drilling due to immediate extraction of the drilling dust.
  • Precision ground tips of carbide metal boards for a fast drilling progress.

Product Description

The fischer hollow drill bit FHD enables drilling and drill hole cleaning in one single step. The dust on the construction site can be reduced enormously preventing the end user, as well as the environment from being exposed to drilling dust. The wear mark on the drill head enables easy identification of the wear limit according to PGM®. Ideal for drilling in sensitive inside spaces (hospitals, labors, food industry...)
  • No conventional cleaning necessary for chemical and mechanical anchoring systems. (With corresponding ETA approval.)
  • Time savings of 55% for the correct drill hole creation process.
  • Optimal drill hole cleaning, for proper installation of anchors and secure fixing. (drilling dust reduces performance of fixing materials).
  • Reducing the drill dust prevents jamming when drilling which provides a faster and frictionless drilling progress.
  • Clean and healthy work due to immediate extraction of drilling dust at the drill bit tip.
  • Centering tip allows for accurate positioning on uneven surfaces reducing slip.

Application and Permission

  • For drilling holes with low dust in combination with chemical and mechanical anchors
  • Ideal for sensitive surroundings where dust should be avoided (hospitals, labors, manufacturing halls, at traffic routes, overhead applications...)
