ZT680-VF-TF 10,000 RPM Rated Vacuum Composite Microstop Cage

Part Number: ZT680-VF-TF

The ZT680-VF-TF 10,000 RPM Rated Microstop Cage, originally designed for composite work, is the ultimate vacuum-ready microstop cage on the market! Boeing and it's subcontractors have standardized on this microstop cage for all of the new B787 program work. Here are a few of the features of this cage:


  • Fail-safe positive stop insures accurate repeatability and eliminates the possibility of work piece damage.
  • Felt dust shield eliminates composite/graphite dust contamination of the radial ball bearings extending cage life.
  • .0005″ incremental depth adjustment.
  • 3/4″ diameter cutter capacity with “VF” style footpiece. For information on other footpieces see the “microstop cages & cutters” section of our website.
  • 1/4″ shaft travel with either 1/4″-28 or 6mm internally threaded shafts.
  • Shaft style available in either in three flats, 1/4″ round or “quick-change” ball lock style.
