How to use

Mount the disc on a compatible angle grinder with a 22 mm spindle or appropriate adapter, following the grinder manufacturer’s mounting instructions. Securely tighten the flange and verify the disc spins freely before use. Use steady, moderate feed pressure and let the diamond segments perform the cutting; avoid forcing the disc. Wear appropriate personal protective equipment (eye, ear, respiratory and hand protection) and ensure the workpiece is firmly supported.

Usage recommendations

For best results, use the Proline PSG disc on clean, stable surfaces and allow occasional pauses during prolonged cutting to reduce heat buildup. Match disc RPM to the grinder’s rated speed and replace the disc when wear affects cutting performance.
