This is a new range of small CoroMill Plura ball nose end mills for profiling applications in medium hard to hard steels, 35-72 HRc.

Small diameters down to 0.1 mm (0.004 inch) make them suitable for all small die and mold manufacturing where high precision is important.

Application
  • Die and mould; manufacturing of small, often plastic, mouldings, forging and casting dies
  • Electronic components
  • Medical tooth implants
  • Hardened steels (35–72 HRc)


ISO application area
H
Technical features
  • Fine-grained solid carbide grade, GC1700, with multi-layered PVD coating having high hardness and high wear resistance
  • Geometry design prevents radius from deteriorating from uneven wear
  • Edge preparation for improved wear behaviour
  • Neck, an advantage in pocket milling
  • High accuracy:
    +0.003 / -0.007 mm
