    Taper Accuracy

    An ER collet is selected during the CNC grinding process to check the 2 taper contact surface's accuracy

Product Spotlight

  • Robotic Automation in Manufacturing


    We optimize our manufacturing workflow for both efficiency and accuracy by utilizing robotic arms to load and unload ER collet stock into the Shigiya CNC grinders which are made in Japan. Combining the robotic arms with a reliable CNC grinder is our formular to control tight tolerance in a mass production environment.

    5 Micron Runout


    Each collet is inspected 3 times at 0, 120, and 240 degree at 4 times diameter to guarantee the 5 micron (0.000197") runout tolerance.  This inspection process is also repeated 3 times with fully disassemble collet from the collet nut and the tool holder to guarantee consistent runout tolerance

  • ER-EM collet does not have a collapse range, unlike the standard collet does
  • Nominal size of ER-EM collet covers the most popular end mill shank size in both inch and metric size
  • ER-EM collet is capable to fit into the standard ER tool holder
  • Made in TAIWAN
  • Conform to DIN6499B
