## Summary description

Diamond crown drill bit DISTAR RM-TX 1 1/4" (32 mm x 450 mm) for dry drilling. Manufactured for cutting and core extraction in masonry, concrete and stone using a compatible rotary tool or drill. Features a diamond-segment cutting edge and a 1 1/4" TX connection for secure mounting. Suitable for dry core drilling tasks in construction and renovation.

## Long description

The Diamond crown drill bit DISTAR RM-TX 1 1/4" 32 mm x 450 mm is a dry-cutting core bit designed for use with compatible rotary tools and drills featuring a 1 1/4" TX connection. Intended for core extraction and hole making in masonry, concrete and natural stone, this bit combines a diamond-segment cutting edge with a long body to reach deeper drilling depths while maintaining stability during dry operation.
Advantages
This diamond crown drill bit offers a durable diamond-segment cutting edge that preserves cutting performance when working in abrasive materials such as concrete and stone. The 1 1/4" TX connection ensures a secure, vibration-minimised mounting in compatible tools, and the 450 mm overall length provides extended reach for deeper cores without the need for extensions. Designed specifically for dry cutting, it eliminates the need for water feed systems when working in environments where wet methods are impractical.
Suitable for
Core drilling holes in reinforced and non-reinforced concrete for installations and through-penetrations
Drilling openings in masonry and brickwork for plumbing, electrical and HVAC runs
Creating pass-throughs in natural stone and similar hard materials during renovation
Dry on-site core extraction when water supply or containment is not available
When it may not be suitable
This dry diamond core bit is not intended for continuous wet drilling applications; frequent wet cutting may reduce its designed performance characteristics. It may also be less effective for drilling in very soft or highly reinforced materials where a specialised bit or different cutting speed is recommended.
Key specifications
Cutting diameter: 32 mm
Total length: 450 mm
Connection type: 1 1/4" TX
Cutting method: dry core drilling
Cutting edge: diamond-segment
How to use
Install the bit into a compatible rotary drill or core drilling machine with a matching 1 1/4" TX mount and ensure the connection is secure before operation. Mark the drilling position and start at low speed to establish the pilot groove, then increase speed and apply steady, even pressure while keeping the tool aligned. Periodically withdraw the bit to remove dust and core material and to prevent overheating; use appropriate dust extraction or respiratory protection when performing dry drilling. Allow the bit to cool between prolonged runs and avoid excessive side loads that could damage the diamond segments.
What to consider before purchase
Compatibility of your tool with a 1 1/4" TX connection
Suitability of dry cutting for the intended work environment and dust control measures
Required hole diameter (32 mm) and drilling depth capability of a 450 mm bit
Material to be drilled (masonry, concrete, stone) and presence of reinforcement
Usage recommendations
Use the bit with an appropriate drill rated for core drilling, keep drilling speeds within manufacturer guidelines for diamond tools, employ dust extraction or wear suitable respiratory protection when dry cutting, and check the bit regularly for wear to maintain cutting efficiency and safety.
