DRILL CHUCK ARBOUR MT-4 JT-6 (1/2")

A Drill Chuck Arbor MT-4 JT-6 (1/2") is a precision tool adapter used in machine shops and drilling setups to securely mount a drill chuck onto a machine spindle. One end of the arbor has a Morse Taper #4 (MT-4) shank that fits into the spindle or quill of a drill press, lathe, or similar machine, and the other end has a Jacobs Taper #6 (JT-6) to accept and hold a drill chuck with a 1/2″ internal taper. This adaptor allows standard drill chucks to be used on machines with MT-4 tapers, ensuring good alignment and torque transfer for accurate drilling operations.
