DART Red Ten SS/Inox Abrasive Thin Metal Cutting Disc 300 x 3.0 x 20mm

When you need stainless steel cutting discs that actually do the job without leaving a ragged edge or bluing the material, the DART Red Ten SS/Inox range is worth knowing about. These 300 x 3.0 x 20mm abrasive discs are built specifically for cutting stainless steel and inox, manufactured to the European standard EN 12413, which covers safety requirements for bonded abrasive products. That standard matters on site. It means the disc has been produced to a consistent spec, not cobbled together and hoping for the best.

The thin profile is the key feature here. A thinner kerf means less material removed, less friction, and less heat fed back into the workpiece. Heat distortion in stainless steel is a genuine problem: the metal moves, the cut line drifts, and you end up with a finish that needs grinding back before it’s usable. These discs are designed to minimise that. Less heat also means less oxidisation at the cut edge, which matters when appearance or corrosion resistance is part of the spec.

Where DART Red Ten Stainless Steel Cutting Discs Perform

On fabrication benches and site installs alike, these discs suit anyone working regularly with stainless tube, sheet, or bar. Handrail fabricators, kitchen equipment installers, and structural steelwork crews all tend to go through cutting discs at a reasonable rate. The Red Ten’s high cutting speed reduces the time per cut, which adds up when you’re working through a list of pieces. Reduced burring is another practical benefit: cleaner cuts mean less time with a flap disc tidying up the edge afterwards.

At 300mm diameter, these are suited to larger angle grinders and cut-off machines running a 20mm bore. If you’re running smaller 115mm or 125mm grinders day-to-day, DART produce the Red Ten range in those sizes too. Worth making sure your machine matches the disc before you order.

For any trade buyer cutting stainless steel regularly, buying in bulk makes obvious sense. The discs are available individually or in box quantities, and the price per disc drops considerably when you buy a full box. The Red Ten SS/Inox is a no-fuss, reliable disc that does what it says.
