## Long description

Diamond crown core bit Flex DISTAR RS-TX 1 1/4" (72 mm x 300 mm) is a segmented-diamond coring tool engineered for dry drilling in concrete, masonry and mineral materials. The bit features a 72 mm cutting diameter and a 300 mm overall length with a 1 1/4" connection compatible with handheld rotary drills and drilling rigs equipped with matching chucks or adaptors. Designed for dry operation, the segmented diamond rim supports efficient penetration and debris evacuation without the need for water supply.
Advantages
The segmented diamond cutting edge delivers fast cutting speed and improved chip removal during dry coring, reducing clogging and overheating risk. Solid core construction and quality diamond segments ensure consistent performance and extended service life when used on appropriate materials. The 1 1/4" connection provides wide compatibility with common drill spindles and adaptors, enabling use with both handheld and rig-mounted equipment. Overall geometry and segment layout are optimized for stability and straightness of the hole under dry conditions.
Suitable for
 Coring holes in reinforced and unreinforced concrete where water use is impractical
 Dry drilling in masonry, brick and natural stone
 Handheld rotary drilling and rig-mounted coring operations with 1 1/4" connection
 Installation of anchors, conduit and pipe penetrations in interior and exterior worksites
Key specifications
 Cutting diameter: 72 mm
 Overall length: 300 mm
 Connection type: 1 1/4" threaded connection
 Cutting edge: segmented diamond rim for dry coring
 Intended operation: dry drilling (without water)
 Compatible equipment: handheld rotary drills and rigs with matching chuck/adaptor
How to use
Secure the core bit in a compatible 1 1/4" chuck or adaptor and mount it on the selected drill or rig. Mark the drilling position and start at low speed to establish the pilot path; then increase speed and apply steady, moderate pressure to maintain chip removal and avoid stalling. Periodically extract the bit to clear accumulated dust and debris, particularly in deeper holes. Monitor bit wear and replace when cutting performance declines or segments show significant reduction.
Usage recommendations
Use appropriate personal protective equipment including eye, ear and dust protection when dry drilling. Ensure the drill or rig has adequate power and torque for coring at 72 mm diameter. Avoid excessive feed force and prolonged continuous operation to prevent overheating; allow short pauses to cool the bit and clear dust. For reinforced concrete, proceed with caution to avoid prolonged contact with rebar and replace the bit if diamond segments become damaged.
