Bosch Guide Tube - 1617000709

Original Bosch guide tube 1617000709 — a precision-machined guide tube designed to restore correct alignment of the striker/piston assembly in Bosch demolition hammers.

This genuine Bosch spare is a direct-fit replacement for Bosch GSH16‑30 / GSH16‑28 and related 11335-series breakers (check your model label to confirm exact fit).

Made from hardened metal and finished to tight tolerances for smooth, low-friction operation, it removes wobble and misfeed issues that cause poor hammer performance.

A straightforward swap that gets your tool back to factory alignment — a reliable choice when you only need the specific power tool parts to repair a single hammer.
