Genuine Makita blade holder / blade adapter (part no. 671015252) — a metal inner flange that secures the cutting blade to the mower’s drive shaft. This original Makita component is the central blade support that sits between the blade and the drive, machined to fit the mower’s spindle and withstand the lateral and centrifugal forces of cutting.
Key technical detail: the blade holder has a central bore sized for a 22.2 mm motor/spindle shaft, so it locates directly on the shaft and accepts the blade sleeve/washer stack used on many Makita lawnmowers. The part is supplied as the single metal flange/holder (often listed as “inner flange” / “blade support”).
Example models this part is documented to fit include Makita PLM4631 and several PLM/PLM‑series mowers such as PLM4110, PLM4120 / PLM4120N, PLM4610 / PLM4611, PLM4621 / PLM4622N2, PLM5113N and PLM5600 (compatibility varies by model year and sub‑model). It’s also used on equivalent Dolmar-branded lawnmowers in the same parts lists.
Why buy this part: if your blade is wobbling, not seating squarely, or the existing flange is worn or damaged, replacing it with this genuine Makita blade holder restores correct blade alignment and clamping on the 22.2 mm spindle and gets your mower back to safe cutting. As this is a genuine Makita replacement listed among Makita parts, it’s made to the original fit and spec.
Notes: verify the exact model and spindle diameter on your mower before ordering—many PLM-series exploded parts diagrams list 671015252 as the inner flange / blade support.
