This is an authentic manufacturer-sourced replacement part which is specially designed for use with DeWALT drills. It allows a user to secure drill bits. This 1/2" capacity chuck uses a 1/2"-20 spindle for mounting to the drill. The light-weight plastic and single-sleeve design provide user comfort while improving efficiency with easier keyless bit changes. The ratcheting action clicks the jaws tightly into place for reduced bit slippage. Keep in mind this high-quality component is sold individually. Due to a replacement some models may require #50 Part Number N016823. Please make sure to refer to the owners manual for the correct installation.
