Certainly more stock removal
The innovative ALUMASTER High Speed Disc 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. It consists of specially developed tungsten carbide cutting inserts, which are fixed to the High Speed Disc.

Advantages:
- 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)
Industries:
- Shipbuilding and yacht construction
- Wagon construction
- Silo and container construction
- Vehicle construction
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.

ALUMASTER with HICOAT coating
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.
Advantages:
- 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.)

HSD-R 50
Special tool for processing aluminium alloys. With the specially developed arbor, it cannot only be used on angle grinders (mounting dia. 10 mm), but also on straight grinders and flexible shaft drives. It is highly suitable for working on hard-to-reach areas and delicate components. Due to the tool diameter of 49 mm, guards are not obligatory.
