Bosch 16mm Keyed Chuck

The Bosch 16mm Keyed Chuck is a replacement drill chuck designed to provide secure, consistent bit clamping across a wide range of drilling applications. With a chuck capacity of 3.0–16.0mm, it accommodates both cylindrical and hex shank drill bits, making it a versatile choice for contractors and tradespeople. The chuck uses a key-operated tightening mechanism, which delivers a reliably strong clamping force each time. This makes it well-suited to applications where consistent bit retention is essential, such as sustained drilling in timber, masonry, or metal. Fitted with a 5/8" – 16 mount, this chuck is compatible with most common corded drills that use this mounting standard. A spare key type A is included, ensuring you can keep working without interruption should the original key be misplaced.
