Genuine Bosch 2609110150 — crown (conversion) gear for Bosch angle grinders. Precision-machined replacement crown wheel designed to sit in the gearbox of 115 / 125 mm grinders; supplied as the single metal crown gear used to transfer the pinion drive to the grinding flange.

Fits a range of Bosch GWS / GFF / PWS mini and angle grinders — include models such as 1375 / 1375A, GWS 660, GWS 6‑100, GWS 850 C , GFF22A and PWS 600 (Cross reference with the 10 digit version number to confirm fit). This genuine Bosch unit is the same crown gear used across many of those grinder models, so it’s a direct drive‑train replacement when the original wheel is worn or damaged — Bosch power tool parts are built to the tool’s original spec.
