  • High Speed Pre-Balanced

    Internal clamping ring's shape is design to minimize out-of-balance compare to the standard off-center o-ring design from other standard ER collet nut, achieving 12,000 RPM without needed to drill holes on the collet nut body when place on a dynamic balanced machine to preserve ER collet nut's body strength.

  • Internal ball bearing tapered raceway eliminates twisting where the collet and nut makes contact, resulting in a smooth and stable collapse of the collet around the cutting tool thus improving overall runout and clamping force
  • Ball bearing is made from Taiwan and the collet nut is balanced to 12,000 RPM
  • Made from alloy steel hardened to 55-56 HRC
  • Internal thread and taper are precision ground
  • Compatible with most standard ER tool holder and ER collets regardless of the brand
