The JET EQUIPMENT JT9-561708-CK is a T-handle chuck key designed for use with Jet drill presses. It serves as a direct replacement or spare accessory for securing and releasing drill bits in the chuck. The T-handle design provides solid grip and torque when tightening or loosening the chuck jaw. This key is sold individually and is the correct chuck interface tool for the TDC 625 chuck specification. Machinists, fabricators, and shop technicians working with Jet drill press equipment will find this a straightforward, application-matched replacement part.
This chuck key is intended for use with Jet brand drill presses that use a 5/8 inch chuck interface. It fits benchtop and floor-standing Jet drill press models that reference the TDC 625 chuck designation. It is a single-piece accessory sold per unit, making it a practical replacement when an original key is lost or worn. Shops running Jet drill press equipment as their primary drilling platform will want to keep this on hand as a direct-fit spare.
Designed for Jet drill presses using the 5/8 inch TDC 625 chuck designation. Consult the model diagram referenced in the product documentation for installation and fitment confirmation specific to your press model.
Chuck key installation and use should be performed by a qualified machinist or shop technician. Always power down the drill press and confirm the spindle has come to a complete stop before inserting the chuck key. Never leave the chuck key inserted in the chuck when the machine is powered or unattended, as ejection can cause serious injury. Refer to the Jet drill press model diagram for proper chuck key engagement points on your specific unit.
