Hollow drill bit FHD

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

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...)

Product Description
