Original Bosch keyless drill chuck (part number 2609003164) — a direct replacement chuck designed for Bosch percussion drills.

Key specs: single-sleeve, keyless clamping range 1.5–13.0 mm (suitable for drill bits with shanks in that range); fits the common 12.7 mm (1/2") × 20 tpi spindle thread used on these Bosch models. This original Bosch unit gives the same fitment and performance you expect from Bosch power tool parts and is built to match the drill’s chuck interface.

Example compatible models (illustrative): PSB 650 RE, PSB 680 RE, PSB 750 RCE / PSB 750 RCA and PSB 8000 RCE — check the 10-digit type number on your tool’s rating plate to confirm exact compatibility before installation.

Simple to install in place of the worn or damaged chuck on the listed PSB-series drills; matches the original part position in the exploded diagrams and restores full bit-holding range up to 13 mm.
