Genuine DeWalt 663315-00 — Gauge plate for blade alignment on DeWalt 82 mm planers. This replacement gauge plate is the small alignment plate used when setting reversible carbide blades so the blade edge sits flush with the guide during installation and depth adjustments (the procedure uses a 2.5 mm hex to tension the blade carrier).

Fits / commonly used in: DeWalt DCP580 series (18 V, 82 mm) and corded D26676 / D26677K planers (and the CA/B* regional variants listed for those models). It is sold as a single genuine DeWalt gauge plate (part 663315-00) for direct replacement in those planer assemblies.

Compact and simple to fit — if your planer uses 82 mm reversible blades and the factory blade‑setting procedure calls for a gauge plate, this original DeWalt part restores proper blade seating and helps get your planer cutting true again.
