Sealey Diamond Cup Grinding Disc - Ø105mm x 22mm

This Sealey Diamond Cup Grinding Disc is specifically designed for the smooth grinding of stone, concrete, and for efficient stock removal on similar hard construction materials.

It is suitable for Sealey and most other brands of Ø115mm and Ø125mm angle grinders. It features a standard 22mm bore.

Yes, grinding hard materials like concrete and stone with a cup disc generates a significant amount of dust. Always use appropriate dust extraction systems and wear respiratory protection.

No, this disc is optimized for stone and concrete. Using it on metal is not recommended and may damage the disc or the material.

Ensure the disc's 22mm bore fits snugly onto the angle grinder's spindle. Secure it with the outer flange and locking nut, tightening firmly with the correct spanner. Always check that it's securely seated and spins freely before operation.

The main benefit is its high efficiency in removing material (stock removal) and providing a smooth surface finish on hard materials like concrete and stone, thanks to the durable diamond grit construction.

Store the disc in a clean, dry place to prevent rust on the metal components and to protect the diamond segments from damage.

Ensure the disc is correctly and securely mounted to the angle grinder. Check if the angle grinder's spindle is damaged or if the disc itself is warped or damaged. If vibration persists, replace the disc.

Check for excessive dust buildup on the disc's grinding segments. Ensure you are applying appropriate pressure; too little pressure can be ineffective, while too much can overheat the disc. Verify that the angle grinder is operating at its rated speed.

Ensure the disc is being used on appropriate materials (stone, concrete). Avoid applying excessive force, which can prematurely wear down the diamond segments. Check for overheating, which can also accelerate wear.
