Genuine DeWalt Outer Flange — part number 490551-00. This outer blade flange locks the saw blade to the arbor on DeWalt plunge/circular plunge saws and works with the blade bolt to keep the blade seated and running true during cuts.

Direct replacement for many DeWalt plunge saw models, including DCS520 (FlexVolt 165mm plunge saw), DC352K and the DC351/DC351KL family, as well as compatible DWS520 variants — check your model’s exploded-parts list to confirm fit.

If your saw’s blade flange is chipped, bent or missing the locating lug, this genuine DeWalt 490551-00 restores correct blade clamping and alignment so you can cut safely and accurately. This is a standard spare used when servicing parts for power tools.
