227959-8 supersedes older part numbers: 227501-5
Original Makita 227959-8 — Spiral Bevel Gear (19 teeth). Precision-machined 19‑tooth spiral bevel pinion designed for the gearbox of Makita cordless angle grinders; it appears in Makita parts diagrams as the spiral bevel gear used on models such as DGA450 and DGA452 /BGA450 and BGA452.
This part is listed as a single gear (QTY 1) in the official parts breakdowns and is shown as the mating/partner pinion to the larger 39‑tooth spiral bevel gear (227502‑3) in the same gearbox assembly — a direct replacement shown alongside earlier part references in Makita diagrams.
If your grinder’s gearbox has worn or chipped teeth, swapping in this original Makita 227959‑8 restores the correct gear ratio and engagement geometry without modifying the tool. It’s an authentic entry in Makita spare parts documentation and is supplied as the exact-fit spiral bevel gear shown in the parts lists for the models named above.
