With the Bosch M14 quick-clamping nut, you can change cutting and grinding discs on your angle grinder completely tool-free. Misplaced pin spanners and frustrating delays on the job are a thing of the past. Thanks to the integrated fold-out bar, you can tighten and release the nut securely using just manual force. The disc centres reliably on the grinder's backing flange for a safe and stable fit. Compatible with models such as the Bosch gws 18V EC, AdvancedGrind 18, gws 18V-10 C, and gws 18V-10 sc with an M14 spindle, it keeps downtime to a minimum.
