Original Makita inner flange 224199-9 — a direct replacement inner flange (Inner Flange 40) used on Makita 5621RD 6-1/2" (165 mm) cordless circular saws.

Made from durable metal and precision-formed to fit the saw’s spindle, this flange centers and clamps blades so they run true and stay securely locked during use.

If your saw shows blade wobble, uneven cuts, or won’t clamp a blade properly, replacing the worn flange with this original Makita part restores correct blade seating, reduces runout, and returns the tool to safe, reliable operation.
