Precision Ground ER20 Collet Set for the MR-1 CNC Gantry Mill

This Set Includes:

  • ER20 collets of the following sizes: 1/16", 3/32", 1/8", 5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16", 1/2
  • Protective Case

ER20 Collets are devices that get installed into the spindle taper of MR-1 to allow it to secure any tool with shank diameter between 1/16” and ½”.

When it comes to collets, not all are created equal. Blindly ordering the cheapest set that you can find is bound to cause headaches down the road. Our premium collets are guaranteed to not have more than 0.0003” of runout as measured at the nose of the collet. Low runout is a necessity for achieving good tool life, surface finish, and part accuracy.
