Bosch 13mm 1/2" 20 UNF Keyless Chuck and SDS Plus Adaptor

The Bosch 13mm 1/2" 20 UNF Keyless Chuck and SDS Plus Adaptor is a two-sleeved keyless drill chuck designed to convert SDS Plus drills for use with conventional cylindrical or hex shank drill bits.

Fitting directly onto the SDS Plus spindle via the integrated adaptor, this chuck removes the need for a separate key during bit changes. The Auto-Lock mechanism provides secure clamping with a simple two-handed sleeve operation, making bit swaps faster and more convenient on site.

With a chuck capacity ranging from 1.5mm to 13.0mm, it accommodates a broad range of standard drill bits, making it a practical addition for contractors and tradespeople who regularly switch between SDS hammer drilling and conventional drilling tasks on the same tool.
