Genuine DeWalt blade adjuster (part number N424765) — direct replacement for the cutter-block assembly on DeWalt 18 V cordless planers. This metal adjuster locates and secures the blade retainer in the cutter block, letting you set and maintain blade depth and alignment; it installs into the cutter-block area and is secured with the two retaining screws shown in the parts diagram.

Fits DeWalt DCP580 series planers (including DCP580, DCP580B and others such as DCP580N / DCP580NT / DCP580P2). If your parts diagram calls out N424765 (or labels “ADJUSTER” at the cutter-block), this is the original DeWalt replacement you need to restore proper blade retention and depth adjustment.
