The tool holders and millholders for wood and PVC CNC machines are made of case-hardened steel. The supply of the material, made by the main Italian steel mills, is accompanied by the 3.1 UNI EN 10204 certifications.

Thermal treatments

A carburization is carried out with a depth of 0.4 - 0.5 mm in order to achieve a value of HRC hardness of 58 ± 2 and a tensile strength of 800-1000 N / mm2.


After the burnishing, the parts are grinded externally and internally, including the threads of the nuts that tighten the collet. This in order to achieve the maximum precision of the mating surfaces.


Tolerance of the cone

The construction parameters and the relative tolerances of the taper are in accordance with DIN standards, in order to guarantee a perfect centering and a correct tightening to the CNC machine


Balancing is performed on request for each toolholder of this product family, through Haimer balancing machines up to class G1 at 40000 rpm for 1 min

Production control

We perform accurate tests on 100% of our production through certified instrumentation:

  • Certified taper control, by calibrated gauges
  • Checking of threads and seats with taper clamps and collet holder, with MG Calibri gauges
