Genuine Makita 766027-7 — 1/2" (13 mm) keyless drill chuck. Designed to replace a worn or damaged chuck and restore secure bit holding without a key, this original Makita part accepts round or hex shank bits from about 1.5 mm up to 13 mm (roughly 1/2"), and threads onto a standard 1/2"-20 UNF spindle for a direct fit.

Features you’ll care about for repair work: keyless, ratcheting / knurled outer sleeve for hand-tight tightening and quick bit changes; all-metal construction for durability under hammer‑drill or driver use; reduces bit slip compared with a worn chuck.
