Restore hammering performance with the original DeWalt 577718-00 eccentric — a precision eccentric cam that translates motor rotation into the piston’s hammering stroke to deliver the impact action in compatible DeWalt rotary hammers.

Precision-machined for consistent impact transfer and smooth seating, this compact eccentric is a direct-fit replacement for models D25500K, D25600K, D25830K, D25551K and D25650K.

Installs into the hammer assembly using the existing pins and retaining hardware for a quick swap; carry this genuine DeWalt component to restore factory-style performance and reduce downtime.

Keep a spare in your shop — it’s one of the key DeWalt parts professionals stock, and an essential item when ordering parts for power tools maintenance and repairs.
