## Long description

Diamond Crown RM-TX 1 1/4" 182mm x 450mm Dry core bit by Flex is a dry coring tool with a 1 1/4" threaded connection, 182 mm cutting diameter and 450 mm overall length. Designed for use with compatible rotary drills and core drilling rigs, this core bit features a diamond-segment cutting crown optimized for dry material removal from masonry, concrete and reinforced concrete. The threaded shank ensures secure attachment to standard drill arbors used in handheld and rig-mounted applications where water cooling is not available or desirable.
Advantages
The diamond-segment crown provides effective cutting performance and an extended segment life under dry conditions. The 1 1/4" threaded connection offers reliable fixation to most standard rotary adapters and core drill spindles, reducing wobble and improving drilling accuracy. The overall length balances reach and rigidity to access deeper holes while maintaining stiffness during drilling into dense materials.
Suitable for
 Dry coring of masonry
 Dry drilling in concrete and reinforced concrete
 Handheld and rig-mounted coring where water supply is impractical
 Creating openings for pipes, conduits and anchor installations
Key specifications
 Cutting diameter: 182 mm
 Overall length: 450 mm
 Connection type: 1 1/4" threaded shank
 Cutting method: dry coring with diamond segments
 Compatible materials: masonry, concrete, reinforced concrete
How to use
Fit the core bit to a compatible rotary drill or core drill rig using the 1 1/4" threaded connection and ensure the shank is tightened securely. Mark the drilling location, start the drill at low speed to establish the cutting path, then increase speed and apply steady, even pressure without forcing the bit. Pause periodically to clear dust from the hole and allow the bit to cool. Use appropriate personal protective equipment including dust extraction or vacuum where possible to limit airborne particles.
Usage recommendations
For best performance and safety when dry coring, maintain steady feed and avoid excessive side load. Use dust extraction or a vacuum attachment where allowed and feasible. Inspect diamond segments regularly for wear and replace the core bit when cutting efficiency or straightness degrades.
