The innovative High Speed Disc ALUMASTER is a unique tool with an extremely high stock removal rate. It is ideal for processing aluminium as it does not generate hazardous or explosive dust. The tool consists of specially developed tungsten carbide cutting inserts, which are fixed to the High Speed Disc. 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.

Special tool for processing aluminium alloys. Alongside angle grinders (mount dia. 10 mm), can also be used on straight grinders and flexible shafts by means of specially developed arbor. Version with HICOAT coating for processing particularly demanding materials. Very well-suited to processing hard-to-reach places and delicate components. A guard is not needed due to the tool diameter of 49 mm. HSD-R version for radial applications.

  • 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, robust cut geometry for maximum safety, extreme durability and ease of work.
  • Specially developed, turnable and replaceable tungsten carbide cutting inserts.
  • Exceptionally high stock removal rate.
  • Extremely high degree of hardness, very low friction coefficient, very low tendency towards adhesion, improved surface quality, and reduced burr formation thanks to the HICOAT coating
Recommendations for use
  • The tool has primarily been designed for use on aluminium, wrought aluminium alloys and cast aluminium. Non-ferrous metals with a relatively low strength and fibre-reinforced plastics can also be machined. This must be checked for the specific application on a case-by-case basis.
  • Do not push the tool deep into the workpiece. The milling disc is not a cutting tool.
  • Do not exert unnecessarily high forces on the tool: The ALUMASTER High Speed Disc already works with low forces.
  • When machining workpiece edges, cut along the edge, never across the edge.
  • Do not decelerate the tool on the workpiece. The cutting inserts may break.
  • Can also be used on very complex materials (thanks to the HICOAT coating) such as lubricating cast aluminium alloys with 5-10 % silicon content, sticky, greasy materials, abrasive cast aluminium alloys with a silicon content of over 15 %, abrasive materials such as fibre-reinforced plastics (FVK), and non-ferrous alloys of higher strength than aluminium (bronze, brass, etc.).
Safety notes
  • It is essential to tighten the flange nut using the appropriate tool, such as a face pin wrench. Clamping systems which are designed to be tightened without the use of an additional tool, i.e. which are tightened by hand, are not permissible.
  • Tighten the mounting bolts of the cutting inserts using the Torx key provided. If used properly, it is designed to provide a tightening torque of around 4 Nm. Alternatively, use a torque spanner with a tightening torque of 4 Nm.
  • Loose cutting inserts may break during use. Therefore, check regularly whether they are attached securely.
  • Do not use damaged cutting inserts! They may break!
