Product Parameters: This keyless drill chuck adapter features an SDS Plus shank and a 1/2-20UNF mount, with a clamping capacity range of 2-13 mm or 1/16-1/2 inches. The body is constructed from metal for durability, and the black exterior is paired with a textured surface that supports a firm and comfortable grip during handling.

Core Features: The keyless single-sleeve design allows for convenient one-handed tightening for faster bit changes and easier operation. Its structure is built for demanding work, while the stop bearing mechanism helps transfer hand-applied torque into stronger gripping force for secure clamping. The SDS quick-change shank also allows for quick conversion from an SDS hammer format to a three-jaw drill chuck setup.

Suitable Scenarios: This adapter is suitable for impact drills with a power of 1050W and higher, and it can be used with cordless drills and corded screwdrivers as described. It is intended for users who need to adapt a powerful two-hole, two-groove hammer tool to a hand drill-style three-jaw chuck for general drilling tasks.

Product Summary: A keyless SDS Plus metal chuck adapter with 1/2-20UNF mount and 2-13 mm capacity, designed for quick conversion, firm grip, and practical use in tougher drilling applications.
