Different versions

The HSD-F 115/125 version is suitable for surface work . The HSD-R 115/125 version has taken the HSD-F one step further. The HSD-R version can be used for surface work as well as radially for milling out root seams or for peripheral milling . The compact HSD-R 50 version enables delicate and hard-to-reach components to be effectively machined.

PFERD also offers the cutting inserts with a premium-quality HICOAT coating for lubricating cast aluminium alloys with a silicon content of 5–10%, abrasive cast aluminium alloys with a silicon content of over 15%, and for other abrasive materials or non-ferrous metals. This prevents tool clogging and abrasive wear, even in use on these particularly demanding materials.

Additional advantages of the HICOAT coating:

  • Extremely hard
  • Very low friction coefficient
  • Very low tendency towards adhesion
  • Improved surface quality
  • Reduced burr formation

Materials for which the HICOAT coating is recommended:

  • Lubricating cast aluminium alloys with 5–10% silicon content
  • Sticky, greasy materials
  • Abrasive cast aluminium alloys with a silicon content > 15%
  • Abrasive materials such as fibre-reinforced plastics (FVK)
  • Non-ferrous alloys of higher strength than aluminium (bronze, brass, etc.)

High Speed Torus Cutter

The High Speed Torus Cutter is an unparalleled tool for use on robots with an extremely high stock removal rate. Thanks to its compact design, the High Speed Torus Cutter is the ideal tool for working in hard-to-reach areas and on delicate points such as grooves, pockets and tight radii and contours.

The Cutter perfectly complements the ALUMASTER High Speed Disc in the HSD-R 50 version and burrs with the ALU cut.
