199154-9 supersedes older part numbers: 763175-3, 196311-0
Original Makita 199154-9 keyless chuck — a genuine Makita replacement designed for straightforward repairs. It accepts drill bits and driver bits from 1.5–13 mm and threads onto a 1/2"-20 UNF spindle, giving a reliable, tool-free (keyless) grip for fast bit changes.
This part is the standard 13 mm quick‑release chuck used on many Makita compact drills and combi drills such as 8413D / BDF440 / BDF450 / BHP452 / BHP446 / DHP456 and DDF466
If the chuck on your drill is worn, stuck, or no longer gripping bits squarely, the original Makita 199154-9 restores proper chuck capacity and spindle fit without modifying the tool. This item is listed and specified as the replacement 1.5–13 mm keyless chuck for those Makita models.
