Description

  • Reduced nose diameter under the flange to allow compatibility to quick change system
  • Taper ground to AT3 or better accuracy standard for maximum contact with spindle
  • Runout is less than 0.0002" from taper to end mill pocket
  • Made of alloy steel and hardened to HRc 58 and all critical surface is precision ground
  • Internal set screw is included and can be used as a stopping pin to prevent end mill or drill from sliding backwards while performing heavy cutting
  • Each holder comes with a lab certificate on its taper accuracy and runout measurement
  • 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
