This tool is especially suitable for marking uneven or rough surfaces with a hardness of up to 50 HRC with a large font and wide line thickness. Workpiece unevenness of up to 7 mm is compensated for.

  • With eccentric needle:
    External cooling is recommended during the marking.
    The marking speed as well as the spindle speed used can be adapted to the marking according to your own individual wishes and requirements. Select between 3 marking needles: 0.1 mm / 0.2 mm / 0.3 mm eccentricity.

    In general: The greater the eccentricity and the higher the spindle speed (or the lower the feed rate), the deeper is the marking.
    The following rule of thumb applies for a clean text:
    Feed (mm/min) x 10 = Spindle speed (rpm)

  • With centric needle:
    External cooling is not necessary during the marking. The maximum marking speed: maximum feed rate. Select between 2 marking needles: 0.5 mm / 1 mm radius at the needle tip (R1).

Marking needles are not included.


The MarkingStar MS20 has reinforced guides and a broader special needle. The setting is made continuously through a knurled nut and can be determined by means of a 0-20 scale. Due to this setting capability with the knurled nut, the tool is optimally suited for small and medium lot sizes. The tool is held preferably in 20 mm collets or Weldon holders. When using the function check, use of Weldon holders is mandatory.


  • Lightning-fast needle change: the marking needle is removed and changed with the aid of a pliers. This is an advantage even when the needle is worn or broken off.
  • More distinct marking through use of an eccentric needle: with the AMF Marker you have the ability to select between conventional rolling and rotary swaging. In rotary swaging, the material is compressed, as well as forced sideways, and "swaged" by the rotation of the marking needle. This requires use of an eccentrically ground needle which, in combination with spindle rotation, creates more distinct marking than conventional rolling.
  • Function check for use in automation: An integrated function check makes the AMF Marker suitable for use in automation. The query takes place via a pneumatic dynamic pressure query. For this purpose, the tool machine needs an internal coolant supply (ICS) and freely, acknowledgeable M command.
  • Maximum flexibility thanks to lightning-fast changes between various needle types
  • Extremely high wear resistance
  • Suitable for marking rough and uneven materials
  • Easy adjustment by means of a knurled nut (possible also when clamped)
