Diamond core drill AWTools 1 1/4 inch 122/430mm for drilling rig, AWTools 1036625

Diamond core drill AWTools 1 1/4" 122/430mm for drilling rig is a cylindrical core bit engineered for extracting precise cores and creating holes in hard substrates. It features a 122 mm cutting diameter and a 430 mm overall length with a 1 1/4" connection designed to fit compatible drilling rigs. The tool is intended for working in concrete, masonry and similar materials where accurate, clean cores are required for sampling, installation of services or structural investigations.

Advantages

The diamond-segmented cutting edge delivers efficient penetration and extended life when used on reinforced concrete and masonry. A standard 1 1/4" connection ensures compatibility with a wide range of drilling rigs and adapters, facilitating quick mounting and replacement. The length and diameter balance provides a stable core barrel for precise extraction while minimizing vibration and deviation during drilling operations.

Key specifications

How to use

Install the core drill onto a compatible drilling rig using the 1 1/4" connection and ensure the chuck or adapter is tightened according to the rig manufacturer's instructions. Position the rig perpendicular to the work surface, start at low speed to establish the pilot cut, then increase speed and apply steady feed pressure. Use adequate water cooling or dust suppression as appropriate for the material and on-site safety requirements. Periodically withdraw the bit to clear debris and inspect the segments for wear.

Recommendations

Operate the tool with proper cooling (water feed) when drilling concrete to extend segment life and reduce dust. Match drill speed and feed pressure to the material hardness and reinforcement presence, and replace the core barrel if excessive vibration or poor cutting performance occurs.
