Diamond hole saw GRAPHITE 122×450 mm, 11 teeth for 58G540 drilling rig

Diamond hole saw GRAPHITE 122×450 mm with 11 teeth is engineered for core drilling large-diameter holes in hard substrates using compatible drilling rigs such as models built to accept this size and tooth configuration. The tool is intended for professional use on concrete, reinforced concrete, masonry and natural stone. Its 122 mm cutting diameter and 450 mm overall length enable deep, clean cores while the diamond cutting edge maintains cutting speed and abrasion resistance when working in abrasive materials.

Advantages

The diamond cutting segment with 11 teeth provides consistent penetration and reduced vibration during drilling, which helps achieve accurate hole geometry. The elongated 450 mm body allows for extended drilling depth in a single pass, minimizing the need for progressive extension. Tungsten-reinforced structure and balanced design improve tool life and reduce the frequency of segment replacement. The saw is compatible with standard core holders on rigs that accept this diameter and tooth pattern.

Suitable for

• Core drilling large holes in concrete and reinforced concrete
• Drilling openings in masonry and brickwork
• Creating passages in natural stone and hard mineral materials
• Installation of pipes, conduits and cable ducts in construction sites

Key specifications

• Cutting diameter: 122 mm
• Overall length: 450 mm
• Number of cutting teeth: 11
• Abrasive edge: diamond segments for hard materials
• Intended mounting: core drill rigs accepting this diameter and tooth configuration

How to use

Mount the hole saw securely to a compatible core drilling rig following the rig manufacturer’s instructions. Ensure the workpiece is stable and mark the intended drilling location. Start drilling at low speed to establish the cut, then increase to the recommended operational speed for the material being drilled. Use continuous water cooling if drilling in reinforced concrete or other dense substrates to reduce overheating and prolong segment life. Withdraw periodically to clear slurry and inspect the cutting edge.

Usage recommendations

For best performance, use the tool on machines with stable feed and rotational control, apply steady axial pressure without forcing the saw, and maintain continuous water supply during extended cuts. Replace the core barrel or segments when wear visibly reduces cutting efficiency.
