Original DeWalt retaining clip (part 488390-00) — a spring-steel circlip sized SW26 (fits a 26 mm groove) with a 1.5 mm section thickness and durable black finish, engineered to secure bearings, washers and springs on the hammer spindle of DeWalt rotary hammers.

This genuine DeWalt clip holds the small components in the hammer assembly to prevent loss or movement under impact and is used across multiple rotary-hammer models including DC212K, DC233, DCH253, DCH273 and DCH364.

Easy to fit with standard circlip pliers, it’s an inexpensive, service-grade replacement to restore correct assembly and reliable performance when servicing DeWalt parts on-site or in the shop.
