Thin Metal Slitting Cutting Discs (Inox)

These stainless steel cutting discs are built for one job and they do it well. Whether you are slitting box section, trimming sheet metal or cutting stainless pipe, the thin 1.0mm profile (1.9mm on the 230mm disc) cuts through quickly without dragging or generating the kind of heat that warps the workpiece. Less heat means less discolouration on stainless, which matters if the cut edge is going to be visible.

Manufactured to European standard EN 12413, these discs meet the safety and performance requirements you would expect from a trade cutting disc. That standard is not just a box-ticking exercise — it covers bond consistency, burst speed testing and dimensional tolerances, all of which directly affect how reliably the disc performs under load.

Where These Stainless Steel Cutting Discs Perform Best

The real advantage of a thin slitting disc over a general-purpose grinding disc is the cutting speed. Less material being removed means less resistance, which means you get through the cut faster and with less effort on the tool. On stainless in particular, where work hardening is a genuine issue if you linger, that speed is not just convenient — it is actually better for the material.

Reduced burring is another practical benefit. It does not eliminate finishing entirely, but a clean slitting cut leaves far less to dress off compared to a thicker disc or an abusive cut with the wrong wheel.

Available Sizes

Three sizes are stocked: 115 x 1.0 x 22.2mm and 125 x 1.0 x 22.2mm for 4.5 and 5 inch angle grinders, and 230 x 1.9 x 22.2mm for 9 inch grinders. Buy individually or in boxes of 25 — at this price, buying in bulk makes sense if you are running through discs regularly on site.
