Genuine DeWalt midway impact sleeve (Part N612522) — a direct-fit metal outer collar for the quick‑release 1/4" (6.35 mm) hex bit holder on compact DeWalt impact drivers. It replaces a worn or sticking chuck nose so your driver locks bits securely and releases smoothly during fast bit changes.

This original DeWalt sleeve measures approximately 20 x 20 x 11.5mm and is made from a hard‑wearing metal with a durable finish to withstand jobsite use and repeated bit changes.

Fits and common examples: DCF809 (Type 1), DCF787 series, DCF887 variants and several MCF/CMCF compact models (for example MCF601/MCF601G2 and CMCF810/CMCF820 variants) — a useful spare when those models show poor bit retention or a sticky release ring.

If you’re keeping a set of DeWalt spare parts on hand for maintenance, this N612522 sleeve is a small, inexpensive item that restores proper chuck function without replacing the whole tool; it’s a commonly stocked power tool parts item for impact driver repairs.
