Keyless Drill Chuck Adapter 2-13mm with 1/4-Inch Hex Shank

This keyless drill chuck adapter converts your impact driver to accept twist drills and step drill bits from 2mm to 13mm in diameter. The three-jaw design grips firmly and securely.

The unit features a 1/4-inch hex shank for quick connection to cordless drills and impact drivers, and mounts via 1/2-20UNF thread. Made from premium alloy steel, it’s built to last through repeated use on job sites and in workshops.

Installation is straightforward: simply insert the adapter into your power tool and tighten. It works with most cordless drill models. Note that the chuck operates in the clockwise direction only—it cannot be used counterclockwise.

The package includes one keyless drill chuck and one 1/4-inch hex shank adaptor. Before purchasing, confirm that the chuck size suits your existing tools and the drill bit range matches your typical tasks.

For reliable performance, ensure bits are fully seated in the chuck jaws before operating your drill.
