Original Bosch part 2600500017 — cupped (dish) washer: a single, metal cupped washer (listed as 2600500017 / 2 600 500 017) used in Bosch tool assemblies to center components and distribute clamping load where a flat washer won’t seat properly.

Fits and application: this washer is shown in Bosch exploded parts diagrams for the GSG 300 foam-rubber cutter (GSG300) as the dish washer used near the roller/guide assembly, and it also appears in parts lists for other Bosch small tools. (for example, it’s listed for some GWB/GWB‑type drills and grinders)

Notes for repair: supplied as the original Bosch replacement part, sold individually, and intended to restore correct spacing and secure fastening in the factory assembly — a small but critical part when a worn or missing washer is causing looseness, noise, or misalignment. Bosch power tool spare parts like this one are useful to get the original fit and function back quickly.
