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.
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...)
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...)
To create approval-compliant drill holes in:
Also suitable for:
Solid sand-lime brick
* You can find detailed information on building materials in the registration document.
The drill dust is evacuated directly at the drilling tip due to the vacuum drill system and the hollow cylindrical shaft.
The hollow drill bit FHD Max has to be used in combination with a vacuum cleaner of the dust class M.
The hollow drill bits FHD Max connect with the usual SDS Max hammer drill bits.
