DEWALT Keyed Chuck:13mm - 1/2" x 20 UNF

The DEWALT Keyed Chuck features a nominal diameter of 13mm, making it suitable for standard drill bits and accessories of that size. It is equipped with a 1/2" x 20 UNF thread size, ensuring precise compatibility with machines designed for this specific drive configuration. This keyed design requires a chuck key for operation, providing a secure mechanical connection that many professionals prefer for consistent torque transfer during heavy-duty drilling tasks.
