## Summary description

Distar KORONA RS6 diamond core bit, 1 1/4" connection, 82 mm cutting diameter and 450 mm overall length, designed for wet drilling. Intended for cutting core samples in concrete, reinforced concrete and masonry using water cooling to extend segment life and reduce dust. Suitable for core drilling rigs and hand-held core drills with compatible thread.

## Long description

Distar KORONA RS6 diamond core bit with a 1 1/4" connection, 82 mm cutting diameter and 450 mm overall length is designed for wet drilling of cores in concrete, reinforced concrete and masonry. The tool uses diamond segments for effective cutting and requires water cooling to reduce dust, extend segment life and maintain optimal cutting speed. It is compatible with core drilling rigs and hand-held core drills that accept a 1 1/4" mounting and is intended for producing clean, accurate cores and through-holes in structural materials.
Advantages
The diamond segments provide high cutting performance and longer service life when used with water cooling. The 82 mm diameter and 450 mm length balance reach and rigidity for core extraction in medium-depth drilling tasks. A standard 1 1/4" connection ensures compatibility with commonly used core drilling equipment. Wet operation reduces airborne dust, improves segment wear characteristics and helps maintain consistent cutting speed over repeated holes.
Suitable for
 Drilling cores in concrete and reinforced concrete
 Creating openings in masonry and brickwork
 Installation of plumbing, electrical and HVAC penetrations
 Use with core drilling rigs and compatible hand-held core drills
When it may not be suitable
This core bit is optimized for wet drilling; using it dry will significantly shorten segment life and increase dust generation, and is therefore not recommended. It may not be appropriate for precision holework in very thin or fragile tile finishes where specialized bits or pilot drilling methods are preferable.
Key specifications
 Cutting diameter: 82 mm
 Overall length: 450 mm
 Connection type: 1 1/4" thread
 Operation mode: wet drilling (water-cooled)
 Primary materials: concrete, reinforced concrete, masonry
How to use
Mount the core bit securely to a compatible core drill or rig with a 1 1/4" connection. Ensure a steady supply of water for cooling at the cutting interface before starting. Start drilling at low speed to establish a stable cut, then increase speed and apply consistent axial pressure without forcing the bit. Periodically withdraw the bit to clear slurry and allow cooling. After completing the hole, stop water flow, disconnect the bit once safe, and clean diamond segments and the inner tube of slurry residue.
What to consider before purchase
 Confirm your drill or rig accepts a 1 1/4" connection
 Plan for wet drilling with an appropriate water supply and slurry management
 Match cutting diameter (82 mm) and overall length (450 mm) to required hole depth and clearance
 Verify suitability for the material to be drilled (concrete, reinforced concrete, masonry)
Usage recommendations
Use continuous water cooling during operation, avoid excessive feed pressure, and periodically clear slurry to maintain optimal cutting speed and maximize segment life; for reinforced concrete, progress with steady, controlled passes rather than aggressive single-step drilling.
