## Long description

Distar KORONA RS8-X 1 1/4" (62 mm x 450 mm) is a diamond core bit designed for wet drilling through concrete, reinforced concrete and masonry. With a 62 mm cutting diameter and 450 mm overall length, this core bit is intended for use with core drilling rigs and rotary drills where coolant or water is applied. The RS8-X features industrial diamond cutting segments engineered to provide efficient penetration and improved lifetime when used in wet conditions.
Advantages
The diamond segments are arranged to balance cutting speed and wear resistance, ensuring stable drilling performance in abrasive materials. Wet drilling reduces dust and heat, helping maintain segment integrity and extending the bit’s service life. The 450 mm length allows drilling of moderate-depth cores without the immediate need for extensions, and the 62 mm diameter suits a range of installation, inspection and service openings.
Suitable for
 Drilling holes in concrete for anchor installation and plumbing or electrical pass-throughs
 Creating core samples in reinforced concrete for testing and inspection
 Wet drilling operations where reduced dust and improved cooling are required
 Contractors and professionals using dedicated core drilling rigs or compatible rotary drilling machines
When it may not be suitable
This core bit is intended specifically for wet drilling; performance and durability will be reduced if used dry. It is not designed for drilling into very soft materials where diamond segments are unnecessary, nor for very large diameter cores beyond its 62 mm size. Use with incompatible chucks or without appropriate cooling may cause rapid wear or damage.
Key specifications
 Cutting diameter: 62 mm (1 1/4")
 Overall length: 450 mm
 Application method: Wet drilling (coolant/water required)
 Material suitability: Concrete, reinforced concrete, masonry
 Cutting segments: Diamond-impregnated industrial segments for abrasive materials
How to use
Mount the Distar KORONA RS8-X core bit on a compatible core drilling rig or rotary drill using the correct arbor or adapter. Ensure the drill and mounting are securely fixed and aligned with the intended drilling axis. Start drilling at low speed to establish a steady contact and apply constant water flow to the cutting face to cool and flush out debris. Use progressive pressure without forcing the bit; allow the diamond segments to cut the material. After reaching the required depth, retract the bit while maintaining water flow to clear slurry.
What to consider before purchase
 Confirm compatibility with your drill’s arbor and mounting system
 Plan for continuous water supply or coolant for wet drilling
 Verify the bit diameter (62 mm) and length (450 mm) meet the required hole size and depth
 Assess substrate type (concrete, reinforced concrete, masonry) to ensure suitability
Usage recommendations
Use steady speed and consistent water flow for best results; inspect the bit regularly for wear and replace when segments are worn or cutting performance declines.
