Genuine DeWalt Roller — part #625825-00. This small rubber roller cushions and guides the lower blade/guard assembly on compatible DeWalt mitre saws, restoring smooth guard movement and preventing metal-on-metal contact.

Key details: single roller sold individually; the retaining/retaining-ring that secures it is a separate part. The roller measures approximately 25 mm diameter by 11 mm thick (approx. 1.00 × 1.00 × 0.45 in as listed). It’s made to press onto the guard pivot area and replace worn or cracked rollers.

Fits (examples): designed for many DeWalt 10"–12" mitre saws — for example DWS780 and DWS782, and DW715, DW716, DW717 and DW718. It’s also listed for select DeWalt cordless/20V mitre saw variants (check your model’s parts diagram to confirm fit).

Simple replacement: if your saw’s lower guard is sticking, squeaking, or the guard no longer seats properly, swapping in this original DeWalt roller will often restore correct guard action and improve safety and cut consistency.
