The CH100 ST13 is compatible with an extensive list of chuck part numbers, making it a practical single-purchase solution for shops and service trucks that run multiple chuck types.

This four-way chuck key is suited for light duty keyed drill chucks found in residential, commercial, and light industrial settings.

Ensure the correct key size engages fully with the chuck pinion before applying torque to avoid rounding the socket. This tool is appropriate for use by any trade professional who regularly services or operates keyed chuck drilling equipment.
