Pioneer Keyless Chuck Plastic Body & Sds Adapt 1/2 - 20

The Pioneer Keyless Chuck with Plastic Body and SDS Plus Adaptor (1/2"–20UNF) is a versatile chuck system designed to allow standard round-shank drill bits to be used in SDS Plus rotary hammer drills. This adaptor is ideal for installers who need to switch between SDS+ masonry bits and conventional HSS, wood, or multi-material bits without changing tools.

The durable plastic-bodied keyless chuck provides secure bit gripping and fast bit changes, while the SDS Plus adaptor ensures stable rotation and efficient power transfer.
