Keyless drill chuck DIAGER 121A, capacity Ø1.5-13 mm, SDS-Plus adapter

DIAGER 121A keyless drill chuck is engineered for users who require a versatile and robust solution for securing drill bits. The DIAGER 121A keyless drill chuck is compatible with both SDS-Plus rotary hammers and devices that use a 1/2"-20 UNF threaded chuck. This flexibility allows users to switch between different drilling machines without the need for extra tools or adapters.

The manual tightening mechanism enables efficient bit changes, supporting diameters from 1.5 mm to 13 mm. The ratchet locking system ensures secure clamping, while the dual plastic sleeves protect the chuck from impacts and wear during operation. The removable SDS-Plus adapter further expands compatibility, making it suitable for a wide range of installation, repair, and mechanical fabrication tasks.

With its compact design, the DIAGER 121A is easy to install and remove, saving time in fast-paced work environments. Its construction supports frequent bit changes, which is essential for professionals in construction, mechanical workshops, or maintenance settings. The combination of manual tightening, ratchet locking, and dual protective sleeves ensures reliable performance and long service life.
