Compression Spring N019351

Keep your bit holder secure with this genuine OEM spring for DeWalt impact drivers. Authorized by the manufacturer and sold individually, this durable metal spring is designed to maintain pressure on the N078437 sleeve and the rest of the bit holder assembly, ensuring that the bit stays firmly in place during use. If the spring fails or becomes worn, the bit may no longer be held securely—making replacement essential for safe and effective operation.

Simply disassemble the bit holder assembly, remove the worn spring, and install the new one in its proper position to restore full functionality.
