Professional dry core bits Ø 52 mm with cooling spiral for soft-impact systems
In sanitary, heating and air-conditioning (HVAC) as well as electrical installation, the diameter 52 mm is the ideal size for pipe penetrations, cable runs and special recesses. Our diamond core bits Ø 52 mm for soft impact have a special cooling spiral in the tube, which drastically reduces heat build-up and reliably prevents the bit head from seizing.
The advantages of the integrated cooling spiral (helix technology)
- Active dust removal: the helical spiral on the bit body pulls the drilling dust backwards like a screw during rotation.
- Effective heat reduction: thanks to the larger surface area and improved airflow of the dust extraction, the core bit cools continuously – this protects the diamond segments in the long term.
- Protection against sticking: the spiral prevents the bit head from seizing in the fine impact dust, even with deep recesses in concrete and heavily reinforced concrete.
Areas of application & materials
These professional core bits are designed especially for waterless dry drilling and handle the following building materials:
- Concrete & reinforced concrete: high-frequency micro-impacts keep the segments sharp and cut through the reinforcement in dry cutting.
- Masonry, brick & sand-lime brick: clean hole edges without chipping.
- Natural stone & clinker: efficient removal with long service life.
Practical tip for use
Always use the core bit in combination with a powerful dust extractor (class M). The negative pressure makes optimal use of the cooling spiral in the tube, removes the dust immediately and keeps the diamond segments permanently sharp.
