Tool Setter enables to measure a tool length 'on a machining center' easily. 
No need to input the recode manually.
Using Tool Setter reduces working time and avoids input error.
※In case you measure a workpiece which blocks electricity by using NS Tool Setter, it is required to use the Magnet Cable together.

i-50 is improved accuracy repeatedly in the adoption of Patent No. 5133884.

Features of the Tool Setter series

NS Tool Setter is available for the tool edge larger than 6mm in diameter.

  • NS Tool Setter makes it possible to measure the tool length (the position of a drill tip) on the machine tools. It saves your machining time!
  • Sub-zero treatment and ultraprecise polish prevent the variation across the ages.
  • It is usable to measure iron and nonferrous metal workpieces.
    *For plastic and wood, use Tool Setter-i [Internal Contact Type].
    If a tool edge is larger than φ6mm, use NS Tool Setter with the magnet cable.

Tool Setter-i is available for the tool edge from 0.03mm to 6mm in diameter

  • Tool Setter-i has been developed for the machine tools with a ceramic spindle.
  • It is available to measure plastic, wood and some other materials which block electricity.
  • Magnets are attached at the bottom, so it can be used with both vertical and holizontal machining centers.

How to measure the tool length with the Tool Setter

How to measure the tool length with Tool setter

Tool presetter is no longer needed for measuring the tool length! With Tool Setter series, working time can be cut dramatically and no more input mistake will happen.

  1. Put NS Tool Setter on the table and lower a spindle as indicated above.
  2. CRT display recodes the position where a tool edge touches.
  3. ①Measurement based on the tool #1
     Reset the recode when the tool #1 touches to Tool Setter.
     Lower tool #2 and input the recode L (the difference from tool #1) to offset.
    ②Measurement based on the machine datum
     Lower the tool #1 from the machine datum and measure the distance Z1.
     Measure the distance Z2 in the same way, and get the offset.


NS Tool Setter is available for iron and nonferrous metal,
Tool Setter-i enables to measure workpieces which block electricity.
