Product Description

The DEWALT 330034-16 is a replacement chuck key designed to tighten and release drill chuck jaws on compatible DEWALT power tools. Chuck keys are a standard service item for keyed drill chucks, allowing the user to firmly seat or remove drill bits and other tooling. This part is installed by electricians, HVAC technicians, general contractors, and maintenance professionals who rely on DEWALT drills in day-to-day trade work.

It is a direct OEM replacement part sourced from DEWALT, making it the correct fit for tools originally supplied with this key.
