How to use

Fit the disc to a compatible 115 mm angle grinder according to the grinder manufacturer’s instructions and ensure the tool is disconnected from power during fitting. Check that the wheel guard is correctly installed and set the correct rotation direction marked on the disc. When cutting, use steady pressure and allow the diamond segments to perform the work; avoid excessive force which can cause overheating or premature wear. Maintain firm, two-handed control of the grinder and make progressive passes for deeper cuts. Follow recommended speeds for angle grinders and allow the disc to cool between prolonged cuts.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection, dust mask and protective gloves. For dusty materials, consider wet cutting or local dust extraction to reduce airborne particles. Inspect the disc before use for cracks or damage and replace if any defects are found. Store the disc flat in a dry place away from direct sunlight and chemical exposure.
