fischer Hollow drill bit FHD Max 28/600/820

Hollow drill bit for drilling with low dust as well as for efficient and approved anchoring

Art.-No. 546605
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

  • Drilling and drill hole cleaning in one single step saves the normal cleaning of chemical and mechanical anchoring when the hollow drill bit is regulated by their respective approvals. This saves up to 55% of the complete drill hole creation process.
  • The drill hole will be cleaned thoroughly guaranteeing a secure fixing (drilling dust reduces performance of fixing materials).
  • Reducing the drill dust prevents jamming when drilling therefore provides a faster and frictionless drilling progress.
  • Immediate extraction of drilling dust at the drill tip for a clean and healthy work place.
  • 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...)
