Makita 415252-4 — genuine Makita dust nozzle/adapter for plate/biscuit joiners. This molded dust nozzle is made to channel chips and dust from the tool’s base into a vacuum or dust bag, restoring proper dust extraction on affected joiners.
The piece is a screw‑in adapter that threads into the tool’s dust port for a secure fit — removal and replacement are straightforward (unscrew the old nozzle and thread the new one in). It’s a robust molded plastic component sized to work with the tool’s dust outlet.
Adapter sizing: listed as a 30 × 25 mm dust adapter (outer ≈ 30 mm, inner ≈ 25 mm), so it mates with small vacuum hoses and Makita dust bags designed for these joiners.
Common fitment examples include Makita biscuit/plate joiner models such as 3901, PJ7000, DPJ180 and BPJ140 (refer to your tool’s parts diagram for exact placement).
Sold as the original Makita replacement part 415252-4 so you get the exact form and fit the tool was built for; ideal for restoring dust collection quickly and simply.
