Milling cutter Rittal 4050.819 — cutter for aluminium and plastic, 6 mm shank, silver teeth

The Rittal 4050.819 milling cutter is a purpose-built tool for machining aluminium and plastic components. It has a 6 mm shank and silver-coloured teeth optimized for cutting non-ferrous metals and thermoplastics. The cutter is compact and lightweight, intended for use in Perforex machining centres BC and Perforex milling terminals MT, as well as for standalone milling operations in workshop and production environments.

Advantages

This milling cutter offers a combination of precision and durability for aluminium and plastic processing. The 6 mm shank provides compatibility with common collet and chuck systems, while the tooth geometry and silver finish are selected to reduce material build-up and improve chip evacuation when working with soft metals and thermoplastics. Its compact design and low weight support easy handling and stable performance in high-precision tasks.

Suitable for

• Precision milling of aluminium profiles and components
• Shaping and finishing thermoplastic parts
• Use in Perforex BC machining centres and Perforex MT milling terminals
• Small-batch production and workshop prototypes

When it may not be suitable

This cutter is optimized for non-ferrous metals and plastics; it is not intended for heavy-duty machining of hardened steels, cast iron or other hard ferrous materials. For large-volume removal of material or roughing work on abrasive or very hard materials, tools with a different geometry, larger shank diameter or specific coating would be more appropriate.

Key specifications

• Material compatibility: aluminium and thermoplastics
• Shank diameter: 6 mm
• Tooth finish: silver-coloured teeth optimized for aluminium
• Construction: compact, lightweight design
• Typical application: precision milling, shaping and finishing

How to use

Install the cutter in a compatible 6 mm collet or chuck and ensure proper clamping to avoid runout. Select spindle speeds and feed rates suitable for aluminium or the specific plastic being machined—typically higher spindle speeds and moderate feeds for aluminium, and adjusted speeds for various thermoplastics to prevent melting or burr formation. Apply appropriate cooling or air blast as required to maintain chip evacuation and surface quality. Use steady, controlled passes for finishing and avoid aggressive depth of cut beyond the cutter’s intended use.

What to consider before purchase

• Confirm compatibility with your machine tool collet/chuck (6 mm shank)
• Verify material types to be machined (aluminium and plastics)
• Consider required surface finish and acceptable material removal rates
• Ensure Perforex BC or MT machine compatibility if planning integration with those systems

Usage recommendations

For best results, use the Rittal 4050.819 with recommended spindle speeds and feeds for aluminium and the specific plastic grade. Monitor tool wear and replace the cutter when cutting performance or surface finish degrades. Employ coolant or compressed air to assist chip removal and to maintain consistent machining quality.
