196309-7 supersedes older part numbers: 766002-3
Original Makita keyless drill chuck — part number 196309-7. Quick-action, keyless chuck with a clamping range of 0.8–10 mm and a threaded mount of 1/2"-20 UNF (≈12.7 mm diameter × 1.27 mm pitch), designed for fast, tool-free bit changes and reliable bit retention.
This is the genuine Makita replacement chuck used on a number of compact cordless drills/drivers — example compatible models include DDF343 (and BDF343), DF347D / 6271D, and earlier 6261D / 6271 / 6281-style machines — it threads directly onto the tool spindle and swaps in without modifying the gearbox.
Built for workshop use, the chuck features a quick-release sleeve (outer sleeve shown as plastic on Makita spare listings) for smooth one‑hand operation and hardened internal jaws to grip bit shanks up to 10 mm. Fitment is by the standard 1/2"-20 UNF spindle thread used on the listed Makita models.
Part number: 196309-7 — original Makita replacement compatible with the models above; ideal when the original chuck is worn, slipping, or damaged and you need a direct-fit swap to restore your drill’s performance.
