Hollow drill bit FHD 

Due to the sharp carbide metal boards and the two exhaust holes at the drill tip the hollow drill bit FHD drills faster and with less dust. Drill hole and construction site cleaning is no longer necessary because of the extraction system which saves 45% of the complete assembly time and besides preserves your lungs. The hollow drill bit FHD additionally provides a secure fixing as cleaning faults will be avoided.
Applications:
• For creating approval complient drill holes in concrete, also suitable
for solid brick, solid sand-lime brick and natural stone
• 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)
Your advantages at a glance:
• 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
45% of the complete assembly time.
• 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.
