Diamond Cutting Disc Proline PSG 125x22 mm for Concrete

Diamond cutting disc Proline PSG 125x22 mm designed for cutting concrete and other mineral materials. The disc has a 125 mm diameter, a 22 mm centre bore and a segmented diamond rim that helps remove material efficiently while allowing cooling during use. It is intended for construction and renovation tasks where precise, fast concrete cutting is required and fits angle grinders with compatible flanges.

Advantages

The segmented diamond rim provides high cutting speed and improved chip clearance for reduced friction and lower heat buildup. The 2.2 mm plate thickness and 7.5 mm cutting segment width balance durability and cutting performance, suitable for repeated use on concrete, masonry and similar materials. The 22 mm centre hole matches common angle grinder flanges for straightforward fitting.

How to use

Fit the Proline PSG 125x22 mm disc onto an angle grinder with a compatible 22 mm flange following the grinder manufacturer’s instructions. Secure the disc with the flange nut, check that rotation direction matches the arrow on the disc, and wear appropriate personal protective equipment including eye, ear and respiratory protection. Make steady, controlled passes through the material without excessive force to maximise disc life and maintain cooling; allow the disc to cool between prolonged cuts if necessary.

Usage recommendations

Use the disc for dry cutting of concrete and masonry on portable angle grinders of suitable speed; avoid lateral pressure and side loads. Inspect the disc for damage before use and replace if cracks or segment loosening are visible. Follow local safety regulations and the power tool manufacturer’s guidelines.
