Technical information

PFERD ALUMASTER High Speed Disc 4-1/2"/5" with HICOAT® Inserts

The innovative High Speed Disc ALUMASTER is a unique tool with an extremely high stock removal rate. It is ideal for processing aluminum as it does not generate hazardous or explosive dust. The ALUMASTER includes specially developed tungsten carbide cutting inserts fixed to the High Speed Disc. Special disc for processing aluminum alloys using an angle grinder. Version with HICOAT® coating for processing particularly demanding materials. Also suited to peripheral milling and milling out root seams. HSD-R version for radial applications. High Speed Disc ALUMASTER HSD-R 4-1/2"/5" HICOAT® including pre-mounted tungsten carbide cutting inserts, hexalobular socket key, and plastic box.

Special features

• Does not generate hazardous or explosive aluminum dust.
• Does not require a dust extraction system.
• Cost-effective and eco-friendly alternative to grinding wheels and flap discs of comparable weight.
• Innovative and powerful milling tool designed for maximum safety, extreme durability, and ease of use.
• 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, all due to the HICOAT® coating

Recommendations for use

• The ALUMASTER has been designed primarily for use on aluminum, wrought aluminum alloys, and cast aluminum. It can also machine non-ferrous metals that have a relatively low strength, and it can machine fiber-reinforced plastics. Check this for the specific application on a case-by-case basis.
• Do not push the disc deep into a workpiece. The milling disc is not a cutting tool.
• Do not exert unnecessarily high forces on the angle grinder. 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 disc while it is touching the workpiece. The cutting inserts may break.
• HICOAT® coating allows for use on very complex materials like cast aluminum alloys with 5-10% silicon content, sticky and greasy materials, abrasive cast aluminum alloys with a silicon content over 15%, abrasive materials like fibre-reinforced plastics (FVK), and non-ferrous alloys that are stronger than aluminum (bronze, brass, etc.).

Safety notes

• The flange nut must be tightened with 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, should not be used.
• Tighten the mounting bolts of the cutting inserts using a torque spanner with a tightening torque of 4 Nm. The part number for the 4 Nm torque spanner is 20135.
• Loose cutting inserts may break during use. Regularly check to make sure they are attached securely.
