Description
Overview:
This genuine DeWalt (Black & Decker) spring is an OEM internal component for SDS‐Plus rotary hammers, used to control and return parts of the impact mechanism for consistent hammering action. Made from hardened spring steel for strength and fatigue resistance, it helps restore smooth operation and reliability during drilling and chiselling in masonry, brick, and concrete. Designed for heavy site and workshop use, it is a direct replacement in many DeWalt tools, including the DCH333 and DCH363. Correct spring performance supports stable percussion, reduces misfires, and helps extend tool life. Supplied to OEM specification under reference 871690, it is suitable for routine maintenance or repair when the original spring is worn, weakened, or damaged.
