FHD Max 20/400/620 - fischer fixings

fischer Hollow drill bit FHD Max 20/400/620

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

Art.-No. 546603

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...)

Advantages

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

Applications

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...)

Assembly Instruction

Functionality

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.
