## Long description

The Flex Diamond crown drill bit RM-TX 1 1/4" (92 mm) x 300 mm is a dry-cutting hole saw designed for creating precise circular openings in hard masonry materials. With a 92 mm cutting diameter and a 300 mm overall length, this diamond crown bit is intended for use with handheld drills and rig-mounted drilling equipment on concrete, brick and natural stone. The segmented diamond rim provides wear-resistant cutting performance for repetitive drilling in construction and installation tasks.
Advantages
The segmented diamond cutting edge delivers fast material removal and consistent hole quality while reducing heat buildup during dry cutting. Its robust steel body resists bending and maintains concentricity for accurate holes. Compatibility with both handheld and rig-mounted drills makes the bit versatile for onsite drilling, and the durable diamond segments extend service life in abrasive masonry materials.
Suitable for
Drilling circular holes in reinforced and non-reinforced concrete
Installing plumbing and electrical penetrations through brick and block walls
Creating openings for HVAC ducts and anchors in natural stone
Onsite construction and retrofit work where dry cutting is required
Key specifications
Cutting diameter: 92 mm (1 1/4")
Overall length: 300 mm
Cutting type: segmented diamond rim for dry cutting
Suitable materials: concrete, brick, masonry, natural stone
Compatibility: handheld drills and rig-mounted drill systems
How to use
Attach the crown drill bit securely to a compatible drill or drilling rig according to the tool manufacturer's instructions. Mark the hole location and start drilling at low speed to establish the pilot track, then increase speed and apply steady axial pressure without forcing the bit. Since this is a dry-cutting diamond bit, pause periodically to avoid overheating and to clear dust from the cutting area. Maintain firm control of the drill and ensure correct alignment to achieve a clean, accurate hole.
Usage recommendations
For best results in demanding materials, use a drill with sufficient power and torque and consider a pilot drill or guide to improve accuracy. Monitor segment wear and replace the bit when cutting performance or hole quality declines. Use appropriate personal protective equipment and dust extraction or wet suppression methods where applicable to reduce airborne silica dust.
