Diamond cup wheels and grinding heads

United Diamond Tools stock a large range of diamond cup wheels in both 5" and 7", so if you need to grind some concrete or have some touch up work to do we have the diamond disc to help.

Spiral grinding wheels are for general purpose grinding of masonry and concrete. The 24 segment Turbo wheels are less aggressive than the 12 segment wheels, and will last longer, but have a higher initial price.

Arrow cup wheels have a segment that will grind and scrape at the same time, allowing quick removal of thick layers. Used for general grinding as well as adhesive, epoxy and paint removal.

Rhomboid cup wheels have an aggressive segment design, which provides fast grinding. Although the segment is smaller than normal cup wheels, these  cup wheels can provide fast grinding speed and outstanding performance. More segments means the cup wheel will last longer, but will have a higher initial price.

The colour codes for the rhomboid cup wheel bonds are:
Pink is a soft bond for hard concrete.
Blue is a medium hard bond for medium concrete.
Black is a hard bond for soft concrete (although two of our wheels are blue for hard).
Then different grits are available in each hardness range.

PCD cup wheels feature extremely rough diamond particles for fast removal of paint, epoxy, mastic, adhesives, urethane and residues. They are more aggressive and longer lasting than standard diamond cup wheels. They are commonly used when conventional diamond cups will not grind the material quick enough or they tend to get clogged up. PCD cup wheels will not load up or smear the coating like a conventional diamond cup wheel.
More diamonds mean a higher initial price. Can be used wet or dry.

Grinding plates in various sizes are also available
