## Long description

Flex DISTAR DIAMOND CROWN RM-TX 1 1/4" 132mm x 450mm DRY is a core drill bit designed for dry drilling in masonry and concrete. The diamond crown construction ensures efficient material removal and extended service life on hard surfaces. It is compatible with rotary drills and core drilling rigs that accept a 1 1/4" (RM-TX) connection and is intended for creating precise circular holes in brick, block and reinforced concrete where dry drilling is required.
Advantages
The diamond crown geometry provides fast cutting and reduced clogging during dry operation, while segmented diamond segments promote heat dissipation and longer segment life. The sturdy steel body maintains concentricity for accurate hole dimensions, and the RM-TX connection offers secure mounting to compatible drill stands and handheld core drills. Overall design balances cutting speed, durability and dimensional stability for professional use.
Suitable for
 Drilling holes in brick and clay block for pipe and conduit passage
 Creating openings in concrete and reinforced concrete for anchor installation
 Dry core drilling where water cooling is impractical or not allowed
 Use with rotary drilling rigs and handheld core drills with RM-TX (1 1/4") fittings
Key specifications
 Cutting diameter: 132 mm
 Overall length: 450 mm
 Connection type: RM-TX (1 1/4") compatible
 Design: segmented diamond crown for dry drilling
 Intended materials: masonry, brick, block, concrete, reinforced concrete
How to use
Install the core bit onto a compatible drill or core rig using the RM-TX (1 1/4") connection and ensure the mounting is secure before starting. Align the bit with the intended hole location and start drilling at low speed to establish a pilot groove, then increase speed as required while maintaining firm, steady pressure. Because the bit is designed for dry operation, monitor heat build-up and use intermittent drilling or brief pauses to allow cooling and remove dust from the cutting area. Clear debris from the core and segments periodically to maintain cutting performance.
Usage recommendations
Use appropriate personal protective equipment including eye and respiratory protection, and ensure adequate dust extraction or local ventilation when dry drilling. For extended bit life on very abrasive or heavily reinforced materials, consider periodic inspection of segments and alternating with light cooling intervals during prolonged runs.
