Techniks 22512 Cat 40 to JT3 Taper Adapter

Product Description

The TECHNIKS 22512 is a CAT to Jacobs Taper adapter designed to connect a CAT 40 outside taper spindle to a JT3 inside taper toolholder or drill chuck. This adapter serves as an interface between a CAT 40 machine spindle and any tooling or chuck with a JT3 Jacobs Taper shank. It features a 1.57-inch projection and a 0.811-inch hole diameter. Machinists and toolroom technicians use this adapter in CNC machining centers and manual milling machines where CAT 40 spindles are standard and JT3 drill chucks or arbors are required.

This adapter is suited for use in machine shops running CAT 40 tooling systems that need to mount JT3 Jacobs Taper drill chucks or similar accessories. It is a common solution in both production and job-shop environments where drill chuck changeovers are frequent. The compact design and defined projection length make it a straightforward fit for standard CAT 40 vertical and horizontal machining center spindles.
