## Summary description

Distar Korona RS8-X diamond core bit, 82 mm diameter and 450 mm length with 1 1/4" thread, designed for wet cutting. Intended for drilling precise holes in concrete, reinforced concrete and masonry using water cooling to prolong segment life and reduce dust. Suitable for use with compatible core drill rigs on construction and renovation tasks.

## Long description

The Distar Korona RS8-X diamond core bit, 82 mm in diameter and 450 mm long with a 1 1/4" connection, is designed for wet cutting of concrete, reinforced concrete and masonry. The core bit uses diamond segments and water cooling to extend cutting life, reduce dust and keep the cutting zone cool. It is intended for use with compatible core drilling rigs and hand-held core drills that accept a 1 1/4" thread for precise hole drilling in construction and renovation tasks.
Advantages
The diamond segments and optimized matrix provide stable cutting performance and a balance between cutting speed and segment life. Wet cutting reduces dust and prevents overheating, which helps maintain segment integrity and produces cleaner holes. The 450 mm overall length allows drilling through typical slab thicknesses and masonry walls while the 82 mm diameter suits common pipe, conduit and anchor hole sizes. Threaded connection ensures secure mounting on compatible core drills.
Suitable for
 Drilling holes for plumbing and electrical conduits in concrete and masonry
 Creating openings for anchors and fixings in reinforced concrete
 Core sampling and making service penetrations in renovation projects
 Use with core drilling rigs and hand-held wet core drills that accept a 1 1/4" thread
When it may not be suitable
This core bit is designed specifically for wet cutting; it is not intended for dry drilling applications. Using it without water cooling may shorten segment life, increase dust and risk overheating. It may also be unsuitable for very soft materials or delicate tile work where a different diamond specification or a smaller diameter bit designed for finishing would be preferable.
Key specifications
 Diameter: 82 mm
 Overall length: 450 mm
 Connection: 1 1/4" threaded
 Cutting method: Wet cutting with diamond segments
 Recommended materials: Concrete, reinforced concrete, masonry
How to use
Mount the core bit securely on a compatible core drill with a 1 1/4" thread following the drill manufacturer's instructions. Use continuous water supply to the cutting zone to cool the diamond segments and remove slurry. Start drilling at low speed to establish the pilot contact, then increase speed and apply steady feed pressure appropriate for the drill and material. Periodically withdraw the bit to flush out debris and check progress. After use, clean the bit and store it dry to prevent corrosion.
What to consider before purchase
 Verify that your core drill accepts a 1 1/4" threaded connection
 Confirm the 82 mm diameter and 450 mm length are suitable for the hole depth and application
 Ensure you will use wet cutting and have an adequate water supply or coolant system
 Check compatibility with the materials you intend to drill (concrete, reinforced concrete, masonry)
Usage recommendations
Use steady, controlled feed pressure and consistent water flow for optimal cutting life. Avoid excessive side loads or twisting during drilling and allow the bit to cool periodically if drilling long runs. Inspect diamond segments for wear and replace the core bit when cutting performance drops significantly.
