Chuck Keys

Drill Chuck Keys & Replacement Chuck Keys:

Chuck keys are essential for tightening and loosening keyed drill chucks, helping secure drill bits correctly before use. This collection includes replacement drill chuck keys, model-specific keys and multi-size 4-way chuck keys from brands including Bosch, GFB, Makita, Number 8 and Promark.

Replacement Chuck Keys for Specific Drill Chucks:

Many chuck keys are designed for a particular chuck type, drill model or fitting rather than being universally interchangeable. The range includes Bosch replacement keys such as S2 Type C, S2 Type D and ZS14 options, as well as several GFB chuck keys for specific chuck configurations.

The GFB Chuck Key 116, for example, is designed to suit compatible Jacobs S2, Metabo and Rohm S2 chuck types. The collection also includes a chuck key specifically suited to a 13mm industrial drill chuck.

Makita Drill Chuck Key:

For Makita users, the range includes a replacement chuck key for the Makita 1/2-inch XAD03 angle drill. This steel key is designed for securing and releasing drill bits in the keyed chuck and provides a direct replacement option when the original key has been lost or damaged.

4-Way Chuck Keys:

If you work with more than one keyed chuck size, a 4-way chuck key can provide greater flexibility. Both Number 8 and Promark 4-way chuck keys are represented in the collection. The Number 8 model incorporates four different key sizes and is suitable for applications such as drill presses with keyed chucks, while the Promark version is designed for use across various drill chucks.

Choosing the Correct Chuck Key:

Compatibility is the most important consideration when buying a replacement chuck key. Chuck keys that look similar can differ in pilot diameter, gear size and overall dimensions, so matching the key to the chuck or drill specification is important.

Where a product lists a chuck type, drill model or size, use that information as your first reference. For example, the Bosch S2 Type D replacement key measures 40mm long with a 4mm width and 6mm diameter, while other keys in the collection use different specifications.

For workshops using several keyed drills, a 4-way chuck key may be convenient. For a particular power tool or industrial chuck, a dedicated replacement key is generally the more precise choice.
