## Summary description

Distar KORONA RS6 diamond core bit, 62 mm diameter and 450 mm length, with 1 1/4" threaded connection for use on standard drilling rigs. Designed for wet drilling, the diamond-segment cutting edge provides efficient cutting in concrete, reinforced concrete and masonry. Suitable for creating clean core holes for plumbing, electrical, HVAC and sampling tasks.

## Long description

Distar KORONA RS6 diamond core bit, 62 mm diameter and 450 mm overall length, with a 1 1/4" threaded connection, is intended for wet core drilling in concrete, reinforced concrete and masonry. The product combines a continuous steel core barrel with diamond-segment cutting edges to produce smooth, accurately sized holes for plumbing, electrical, HVAC installation and material sampling. The construction is optimized for use with water cooling to prolong segment life and improve cutting speed.
Advantages
The Distar KORONA RS6 offers consistent hole quality and straightness due to its rigid steel body and high-quality diamond segments. Wet drilling reduces dust and heat, which preserves segment integrity and extends usable life. A standard 1 1/4" thread ensures compatibility with many drill rigs and adapters used in professional and trade applications. The 62 mm diameter is suited to common penetrations while the 450 mm length provides adequate reach for many wall and slab thicknesses.
Suitable for
Wet core drilling in concrete and reinforced concrete
Creating openings for plumbing and pipe installation
Drilling holes for electrical conduits and wiring routes
HVAC penetrations and ductwork preparation
Collecting core samples for inspection and testing
When it may not be suitable
This core bit is designed specifically for wet drilling; using it dry will accelerate wear and may damage both the bit and the workpiece. It is not intended for use on very soft materials such as pure gypsum board or for abrasive materials where diamond segments would clog quickly. For diameters or lengths outside the 62 mm x 450 mm range, choose a different size to match the application.
Key specifications
Cutting diameter: 62 mm
Total length: 450 mm
Thread connection: 1 1/4" (standard drill rig thread)
Recommended drilling method: wet
Suitable materials: concrete, reinforced concrete, masonry
How to use
Mount the core bit onto a compatible drilling rig or adapter with the 1 1/4" thread and secure according to the drill manufacturer’s instructions. Use continuous water flow to cool the cutting segments and flush debris; this can be achieved via an integrated water feed or external supply. Start drilling at low speed to establish the pilot engagement, then increase to a steady speed appropriate for the rig and material. Apply moderate, even feed pressure; avoid excessive force which can overload the motor or damage segments. After cutting, withdraw the core bit while continuing water flow to clear the hole and segments.
What to consider before purchase
Confirm compatibility of the 1 1/4" thread with your drill rig or obtain the correct adapter
Ensure you can provide adequate water supply for wet drilling
Match the 62 mm diameter and 450 mm length to the required hole size and material thickness
Check that the target material is concrete, reinforced concrete or masonry for optimal performance
Usage recommendations
For best results, use the Distar KORONA RS6 with a drill rig capable of steady torque and with a continuous water feed. Monitor segment wear and avoid prolonged dry operation. When drilling reinforced concrete, maintain steady speed and allow the bit to cut through rebar intersections gradually to prevent sudden shocks to the segments.
