## Long description

Extension for diamond core drill bits by Diam, 200 mm length designed to work with 1 1/4" core bits. This drill bit extension increases reach while keeping the core bit aligned with the drilling rig, enabling deeper or more accessible coring operations in construction and masonry applications. The extension is engineered to maintain concentricity and secure connection between the coring tool and the drive shaft.
Advantages
The 200 mm extension provides additional reach without compromising stability, helping to preserve hole accuracy and reduce deviation during coring. Its compatibility with 1 1/4" diamond core bits ensures a straightforward connection to standard coring systems. The extension is suitable for repeated on-site use and designed to withstand the forces encountered in wet and dry coring where increased penetration or clearance is needed.
Suitable for
Construction site drilling where extra penetration depth is required
Masonry coring in brick, block, and concrete walls
Utility and mechanical installations requiring access behind obstacles
Situations needing extended clearance from the drill rig to the work surface
Key specifications
Length: 200 mm
Intended core bit connection size: 1 1/4" (one and one quarter inch)
Type: diamond core bit extension for coring systems
Function: extends reach and maintains alignment between drill rig and core bit
How to use
Attach the extension between the drill rig drive shaft and the 1 1/4" diamond core bit, ensuring threads or connection interfaces engage fully and are tightened according to the coring system manufacturer's torque recommendations. Verify concentricity before starting the motor and use appropriate cooling (water) and feed rates for the material being drilled. Monitor the connection during use and stop periodically to clear slurry and check for wear or loosening of the connection.
Usage recommendations
Use with compatible diamond core bits and coring rigs rated for the application; maintain water cooling for prolonged diamond life and reduced dust; inspect connections before each use and replace the extension if threads or centering features show significant wear.
