Hollow drill with core bit ring

The diamond hollow drills with core bit ring for drilling holes in granite are equipped with a powerful coating for above-average drilling progress. Even in difficult hard rock, they always remain easy to cut. On request, we also manufacture diamond hollow drills for universal use in hard and soft rock.

Due to lateral slots in the drill bit, they allow a permanent internal water supply. Our standard drill bits from diameter 6mm up to diameter 35mm in millimeter increments are permanently available in our product range. In addition, larger diameters are also available as drill bit occupancy, intermediate sizes on request. All hollow drills have a standard working length of 120mm.

For rotary head saws we also manufacture diamond hollow drills with R1/2" left-hand thread.

Not the right working length? No problem, we are happy to adapt the working length of our hollow drills to your specifications if one of our standard drills is not appropriate. Drills up to a working length of more than 500mm are also no problem for us.
