The Bosch 13mm Keyless Chuck is a replacement drill chuck designed for compatible Bosch impact drills, offering a capacity range of 1.5mm to 13mm and a 1/2" 20 UNF thread mount. Featuring a keyless design, the chuck clamps drill bits securely with minimal effort — no chuck key required. This makes bit changes quicker and more convenient on site, particularly when switching between drill sizes during repetitive tasks. Supplied as a genuine Bosch system chuck, it is a direct replacement part for a range of Bosch GSB and PSB corded hammer drills. If your existing chuck has worn or become unreliable, this is a straightforward like-for-like upgrade that restores full drilling performance.
