Professional diamond core bits Ø 82 mm for dry drilling in concrete & reinforced concrete
In electrical and building services, the diameter 82 mm is the standard for recessing switch and junction boxes. Our dry Diamond Core Bit Ø 82mm for Soft Impact were developed specially to manage completely without cooling water even in hard building fabric.
Maximum performance in extremely hard building materials
Thanks to state-of-the-art bonding technology and laser-welded segments, these core bits easily handle the following materials under soft-impact or micro-impact action:
- Concrete & reinforced concrete: the high-frequency impacts keep the diamonds sharp and reliably cut through the reinforcement in dry cutting.
- Masonry, brick & sand-lime brick: clean hole edges without chipping for exactly fitting flush-mounted boxes.
- Natural stone & clinker: efficient removal with long service life.
Advantages of dry drilling with soft impact
- No water damage & slurry: ideal for renovation of old buildings, inhabited interiors or sites without a water connection.
- High segment safety: laser-welded diamond segments prevent tearing off when hitting reinforcement or under heavy impact.
- Fast drilling progress: the micro impact continuously re-sharpens the diamonds and prevents glazing of the segments.
Practical tip for use
When dry drilling in concrete and reinforced concrete, always use a powerful dust extractor (class M). The airflow generated cools the bit head, removes the drilling dust directly and maximises the service life of the tool.
