Product Spotlight

  • Dynamically balanced to G2.5 25,000 RPM to meet today's demanding need in aggressive high speed machining

  • In a generic standard ER collet nut, an internal ring is off-centered so that an ER collet can be easily snapped into it and holds the ER collet in place.  To minimize this off-centering, SHARS ER collet nut is optimized to distribute the flat sides' area to off-set the off-center. ER collet nut is also balanced with each holder


  • Made from alloy steel harden to 54-60 HRc
  • All critical surface are precision ground

  • Concentricity is less than 0.0001" from taper to end mill pocket
  • Each holder comes with a lab certificate on its taper accuracy and runout measurement

  • Coolant through capability
