## Long description

The Diamond Crown RM-TX 72mm x 450mm is a professional-grade diamond core bit engineered specifically for dry drilling applications. Designed to deliver high performance in demanding construction environments, this tool features a robust construction that ensures stability and precision when working with hard masonry materials. Its 1 1/4" connection makes it compatible with a wide range of standard professional drilling rigs, providing a secure fit and efficient power transfer during operation.
Advantages
This diamond core bit stands out due to its specialized design for dry drilling, which eliminates the need for water supply systems in many common masonry tasks. The high-quality diamond segments are optimized for fast cutting speeds and extended tool life, allowing for consistent results even during intensive use. The 450mm working length provides sufficient depth for most standard wall and floor penetrations, while the 72mm diameter is perfectly suited for installing pipes, cables, and ventilation ducts with high accuracy and minimal material breakout.
Suitable for
Drilling holes in brickwork and masonry
Installation of electrical conduits and wiring
Creating openings for plumbing and heating pipes
Ventilation system installations
Renovation and construction site drilling tasks
When it may not be suitable
This core bit is not intended for use on reinforced concrete or extremely hard natural stone, as these materials typically require wet drilling techniques to prevent segment overheating and premature wear. It is also not compatible with handheld drills that lack the necessary torque and stability required for core drilling.
Key specifications
Diameter: 72 mm
Working length: 450 mm
Connection type: 1 1/4" UNC
Drilling method: Dry
Application: Masonry and brick
How to use
To use the Diamond Crown RM-TX, ensure it is securely mounted to a compatible professional drilling rig. Begin the drilling process by positioning the bit at the desired location, using a centering device if necessary to prevent wandering. Apply steady, controlled pressure, allowing the diamond segments to do the work without forcing the tool. Periodically retract the bit to clear dust and debris from the hole, which helps maintain cutting efficiency and prevents the tool from overheating during operation.
What to consider before purchase
Verify that your drilling rig supports the 1 1/4" connection type.
Ensure the drilling equipment has sufficient power for a 72mm diameter bit.
Confirm the material to be drilled is suitable for dry diamond drilling.
Check if a dust extraction system is available to maintain a clean workspace.
Usage recommendations
Always wear appropriate personal protective equipment, including safety glasses and a dust mask, when performing dry drilling. Ensure the drilling rig is properly anchored to prevent vibration and ensure a clean, straight hole.
