Original Bosch chuck-and-key assembly (part no. 1608571069) — a keyed three‑jaw chuck rated for 13 mm drill bits and supplied with its matching chuck key. It’s the same style chuck used on Bosch hammer and rotary drills so you get firm, positive bit retention for drilling and light hammering tasks.

Fits a range of Bosch hammer/rotary drill models (examples: 11228VS, 11239VS, 11218EVS, 11221DVS, 1169VSR, 1194VSR, GBH2‑24 series) and is also listed as compatible with some Skil models such as the 6443. Use this part when the jaws are worn, the chuck no longer grips reliably, or the keyed mechanism is damaged.

Made as a direct replacement chuck-and-key assembly, it mounts with the tool’s standard spindle thread and includes the retaining screw inside the chuck (note: that screw is typically reverse‑thread and must be removed before unthreading the old chuck). Installation is straightforward — the chuck threads on and the key tightens the three jaws evenly for secure clamping.

If your drill accepts a 13 mm (≈1/2 in) keyed chuck and or one of the models above, this original Bosch 1608571069 will restore correct bit holding and extend the life of the tool.
