## Summary description

Distar KORONA RS6 diamond core bit with a 52 mm (1 1/4") cutting diameter and 450 mm length, designed for wet drilling. Manufactured for cutting and core removal in concrete, reinforced concrete, masonry and similar materials. Suited for use with core drill rigs and handheld drilling units that support wet cooling to extend tool life and improve cutting performance.

## Long description

Distar KORONA RS6 diamond core bit, 52 mm (1 1/4") cutting diameter and 450 mm overall length, designed for wet drilling in concrete, reinforced concrete, masonry and similar mineral materials. The bit features a segmented diamond crown intended for efficient cutting and core extraction when used with core drilling rigs or handheld drills that provide water cooling. The construction and diamond bond are optimized for abrasive and reinforced substrates, giving a balance of cutting speed and lifespan under wet conditions.
Advantages
The Distar KORONA RS6 core bit provides consistent circular cutting performance with reduced heat thanks to wet cooling, which preserves the diamond segments and minimizes glazing. Its 52 mm diameter and 450 mm length allow drilling full-depth cores in standard applications while maintaining good chip evacuation through the segmented crown. The product is compatible with common core drill chucks and rigs when used according to the recommended wet-drilling setup.
Suitable for
 Drilling holes in concrete for anchors, pipes, and electrical conduits
 Creating openings in reinforced concrete and masonry during renovation or installation work
 Use on core drilling rigs and handheld core drills with water supply for wet drilling
 Applications where a 52 mm (1 1/4") diameter core is required
When it may not be suitable
This diamond core bit is intended specifically for wet drilling. It may not perform well or may suffer rapid damage if used dry or without adequate water cooling. The bit is not designed for drilling in soft materials where faster cutting tools or masonry bits would be more efficient, nor is it intended for use on non-mineral materials such as wood or plastics.
Key specifications
 Cutting diameter: 52 mm (1 1/4")
 Overall length: 450 mm
 Cutting method: Wet drilling with water cooling
 Intended materials: Concrete, reinforced concrete, masonry and similar mineral substrates
 Segment type: Segmented diamond crown for chip removal and cooling
How to use
Mount the Distar KORONA RS6 core bit securely in a compatible core drilling chuck or adapter. Ensure the drill rig or handheld core drill is rated for the bit length and diameter. Supply a steady flow of water to the cutting area before and during drilling to cool the segments and flush out debris. Start drilling at low speed to establish the groove, then apply steady pressure and maintain rotational speed appropriate for concrete drilling. Withdraw the bit periodically if required to clear the core and prevent clogging. After use, clean the bit and store it dry to avoid corrosion of the arbor.
What to consider before purchase
 Verify that your core drill or rig supports wet drilling and the 52 mm (1 1/4") diameter.
 Confirm the required drilling depth matches the 450 mm length of the bit.
 Assess the substrate type (reinforced concrete, plain concrete, masonry) to ensure diamond segmented bits are appropriate.
 Plan for water supply and slurry management on the job site to ensure safe wet drilling.
Usage recommendations
Use continuous water flow and moderate, steady feed pressure. For reinforced concrete, monitor segment wear and adjust feed rate to avoid excessive vibrations. Replace the bit if diamond segments show heavy wear or if cutting performance degrades significantly.
