A cutting disc is thin and designed to cut on its edge only. Using one on its face, or exceeding the rpm printed on the label, is how discs shatter, so check the disc rating against your grinder before fitting.

Greyhound Auto Retail stocks cutting discs for metal and masonry in the common diameters and bore sizes, in single units and bulk packs for workshops.

Let the disc cut at its own pace rather than forcing it, wear eye protection every time, and never remove the guard. Nationwide delivery across South Africa.
