KWB 791250 Depressed Centre Cutting Disc 125 x 1.0 mm for Metal, Stainless Steel, Sheet Metal, Universal, Aluminium Oxide, 80 m/s, 12,200 RPM, EN 12413

On a busy fabrication floor, a metalworker reaches for the KWB 791250 to slice through a stainless steel panel. The disc bites cleanly, leaving a burr-free edge that requires minimal rework. This 125 mm depressed centre cutting disc is engineered for angle grinders, delivering fast, precise cuts in sheet metal, steel, and stainless steel. Its thin 1.0 mm profile reduces material loss and heat build-up, while the aluminium oxide abrasive with resinoid bonding ensures a long service life and consistent performance. Fiberglass mesh reinforcement adds strength and safety, allowing the disc to withstand high rotational speeds up to 12,200 RPM (80 m/s peripheral speed). Compliant with EN 12413, it is a reliable choice for professional and DIY applications.

Good to know

For optimal performance and safety, always use the disc with a properly guarded angle grinder and wear appropriate personal protective equipment, including eye protection and gloves. Ensure the disc is rated for your grinder's speed and never exceed the marked maximum RPM. Store discs in a dry place away from excessive heat and moisture to maintain their integrity.
