The JET jt9-28813-008 is a replacement jaw insert set designed for use with JET power tool chucks and clamping accessories. The set includes two jaw inserts and four mounting screws, providing everything needed for a complete jaw replacement. These inserts restore proper clamping function to worn or damaged chuck assemblies and are installed by machinists and tool repair technicians working on JET-brand equipment. Keeping jaw inserts in serviceable condition is essential for maintaining accurate workpiece holding and safe machine operation.
This jaw insert set is suited for professional shop environments where JET chucks or vise assemblies require routine maintenance or component-level repair. The set is intended as a direct replacement for worn inserts and is appropriate for both production shops and maintenance departments that service JET power tools and accessories on a recurring basis.
Designed as an OEM-style replacement jaw insert set for compatible JET chuck and clamping accessories.
Installation should be performed by a qualified machinist or tool repair technician. Power down and fully de-energize the machine before beginning any chuck or jaw service. Use the provided screws and appropriate hand tools to seat the inserts securely before returning the tool to service. Follow the equipment manufacturer's service documentation for torque and assembly guidance.
