End-mills NEVER pull out from these holders!
SLIMLINE Z allows efficient machining of tough materials thanks to its four safety configurations.
It eliminates concerns of the tool pulling out due to chattering or abrupt increases in cutting force.

  • Tool life extended when doing heavy duty machining.
  • Absolutely no worry of the tool slipping and pulling out, even if the tool experiences chattering.


Z-shank tools

The Z shank tool is required for SLIMLINE Z. The Z shank tool is required for SLIMLINE Z. Z Shank is easy to fabricate — the open standards make it possible for anyone to fabricate block shanks.
For additional processing of Z Shanks, please contact MST Corporation. We accept machining requests for one or more shanks.

They can provide a tool for SLIMLINE Z





Conventional holder

Side lock holder

Side lock holder

  • Short tool life due to poor run-out accuracy.
  • Removing the set-screw after machining is difficult.
  • Not available for use with through-spindle coolant.

Milling chuck

Milling chuck

  • The nut causes increased interference
  • The insufficiently short gripping area on the tool shank causes unstable machining.
  • Less rigidity for side loads due to the thin body thickness.

Easy to operate

The installation of a tool requires a
shrink-fit heater (option).
