This Genuine DeWalt connecting rod (con rod) is a direct replacement for selected SDS‐Plus rotary hammer drills, including the DCH283 and D25333K. Manufactured from precision‐machined steel with a robust metallic finish, it links the motor drive to the hammering mechanism to maintain smooth percussion and efficient power transfer. The part restores correct motion and impact energy when the original rod has worn, helping to keep drilling and chiselling performance consistent on site and in the workshop. Supplied to OEM specification under part number N390874, it is designed for reliable fit and function within the tool’s internal assembly. Suitable for routine servicing or repair of heavy‐use tools in construction, maintenance, and DIY environments.
