Mounting Plates For Easy-Set™ 3-Jaw and 6-Jaw Chucks

Ajaxtoolsupply.com Sales and Service 1(800)543-5998 offers a full line of Atlas Workholding Mounting Plates type "D", "A", "L" and threaded plates for the Easy-Set™ Chucks.

Our Mounting Plates are interchangeable with other popular adjustable universal style Chucks.

Mounting plates are precision machined to suit the spindle nose of your machine.

For maximum accuracy of mounting plates, mount plate on machine spindle nose, place a dial indicator on the chuck side face of the adapter close to the mounting holes, rotate the adapter and if the total indicator reading (TIR) exceeds .0005" take a light truing cut across the face of the mounting plate.
