ALUMASTER High Speed Disc


  • Does not generate hazardous or explosive dust.
  • An extraction system is not required.
  • Cost-effective and eco-friendly alternative to grinding wheels and flap discs of comparable weight.
  • Innovative and robust cut geometry:
    • The highest degree of safety
    • Extreme durability
    • Comfortable work
  • Specially developed, turnable and replaceable tungsten carbide cutting inserts.
  • Exceptionally high stock removal rate.

Materials that can be worked:

  • Aluminium alloys
  • Brass, copper, zinc
  • Bronze
  • Plastics
  • Fibre-reinforced duroplastics (GRP, CRP)


  • Shipbuilding and yacht construction
  • Wagon construction
  • Silo and container construction
  • Vehicle construction


PFERD also offers the cutting inserts with a premium-quality HICOAT coating for lubricated aluminium casting 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.


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

Materials that can be worked:

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