## Long description

The Flex Diamond crown core drill bit RS-TX 1 1/4" (82 mm) x 450 mm is a dry-drilling core bit designed for efficient removal of cores in concrete, reinforced concrete and masonry. With a diamond-segment cutting edge, this core bit enables wear-resistant cutting without the need for water cooling, making it suitable for on-site drilling where wet methods are impractical. The 450 mm overall length provides deep penetration for common installation and construction tasks while remaining compatible with handheld and rig-mounted rotary drills.
Advantages
The diamond-segment rim offers high abrasion resistance and stable cutting performance during dry drilling. Its construction is optimized for quick core extraction and long service life under typical construction-site conditions. Compatibility with both handheld and rig-mounted rotary drills ensures flexibility in application and simplifies tool setup for different jobs. The size 1 1/4" (82 mm) diameter balances a common opening size with effective material removal in a single pass.
Suitable for
Creating service openings for plumbing and electrical installations in reinforced concrete
Core sampling and drilling for anchoring or pipe penetration in masonry
On-site dry drilling where water supply or containment is limited
Handheld or rig-mounted rotary drilling in renovation and construction projects
Key specifications
Diameter: 82 mm (1 1/4")
Total length: 450 mm
Cutting edge: diamond-segment rim for dry cutting
Application material: concrete, reinforced concrete, masonry
Use method: dry drilling, compatible with handheld and rig-mounted rotary drills
How to use
Secure the core bit to a compatible rotary drill according to the drill manufacturer's instructions, ensuring the chuck or adaptor is rated for the bit size and operating speed. Mark the drilling location and stabilize the drill—use a drill rig for deep or precision holes and a guide or stand for handheld operation. Start at low speed to establish the cut, then apply steady pressure and increase speed as recommended for the drill and material. Periodically withdraw the bit to clear dust and allow cooling; while designed for dry use, avoid prolonged continuous operation to prevent overheating. After completing the hole, remove the core and inspect the bit for wear before subsequent use.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, dust mask or dust extraction, and hearing protection. For prolonged drilling or multiple holes, consider using a drill rig or intermittent drilling technique to extend bit life and maintain cutting performance.
