125mm Diamond Grinding Cup Wheel - Double Row Concrete Grinding Disc for Angle Grinders

The My Tool Expert 125mm diamond grinding cup wheel is a double-row concrete grinding disc for 125mm angle grinders. Twenty double-row diamond segments on a heat-treated steel body take down high spots, old adhesive and coatings quickly, and cooling holes in the body let air through the wheel to carry heat away.

Use it to level and clean up concrete and screed, strip tile adhesive and carpet glue before re-tiling or re-flooring, remove paint and graffiti from masonry, and smooth granite, marble and natural stone. For grinding indoors, fit it inside our 125mm surface grinding dust shroud, or buy both together in the concrete grinding kit.

Features

• Double-row diamond segments - 20 segments in two rows for fast, even material removal on concrete, screed and stone.
• Cooling holes - air holes in the body reduce heat build-up and help clear residue, so the wheel lasts longer.
• Standard 22.23mm bore - fits 125mm angle grinders with the standard spindle and flange.
• Safety marked - EN 13236 marked and rated to a maximum of 12,250 rpm (80 m/s).
• One wheel, many jobs - rated for concrete, screed, render, tile adhesive, carpet glue, paint, graffiti, asphalt, block pavers, masonry, granite, marble, Indian sandstone and natural stone.

Technical data

How to use a grinding cup wheel

A cup wheel grinds with its face, not its edge. Hold the grinder so the segments sit flat on the surface and keep it moving in steady, overlapping passes rather than dwelling in one spot. It is for surface grinding only: never use it to cut. If you are not sure which grinder size you have, read 115mm vs 125mm angle grinder discs.

Grinding concrete, stone and masonry releases fine silica dust. Use the wheel inside a dust shroud connected to an M-class extractor, and wear eye, ear and respiratory protection.
