ER Collet Sleeves & Drill Chucks for Swiss-Type CNC Machines

Swiss Precision ER Collet Sleeves / Drill Sleeves

ER Style Collets are the tool holding system of choice for use in Swiss-Type machine applications.

Swiss Precision collet sleeves provide rigid & accurate holding of ID tooling. These collet sleeves feature ground shanks and tapers. Mini nuts are used to reduce interference and to make setup and tool changing easier than collet sleeves with hexagonal clamping nuts.

  • Locking flat prevents damage to sleeve shank and provides
    orientation for use with boring bars.
  • Precision ground & case hardened for accuracy and precision
  • Internal stop screw prevents tool pushback
  • Can be used for coolant-thru applications
