Milling cutter set Rittal 4050.818, standard milling cutters for metal/plastic, 6 mm shank

Rittal 4050.818 is a set of standard milling cutters with a 6 mm shank designed for machining metal and plastic. The cutters suit both CNC machines and manual milling operations, providing basic tools for profile shaping, slotting and finishing tasks. Compatible with Perforex machining centres and Perforex milling terminals, this set is intended for workshop and industrial maintenance use where reliable, general-purpose cutters are required.

Advantages

The set includes standard geometries that balance cutting performance and tool life for a variety of materials, including steel and stainless steel. A 6 mm shank ensures compatibility with common tool holders and collets, allowing straightforward integration into existing setups. The cutters are suitable for producing clean slots and profiles and offer consistent diameters for repeatable results in small to medium batch work.

Suitable for

• General-purpose milling of metal components in workshops
• Machining plastic parts that require clean edges and profiles
• Use in Perforex machining centres and compatible milling terminals
• Maintenance and repair tasks requiring quick tool changes

When it may not be suitable

This milling cutter set is intended as a standard, general-purpose solution and may not meet the requirements for high-speed production, heavy roughing, or highly abrasive materials. For precision finishing, micro-machining, very hard alloys or long uninterrupted runs, specialised cutters with advanced coatings, different geometries or larger diameters may be more appropriate.

Key specifications

• Shank diameter: 6 mm
• Intended materials: metal (including steel and stainless steel) and plastic
• Application: profile shaping, slotting, finishing
• Compatible machines: CNC milling machines, manual mills, Perforex machining centres and milling terminals

How to use

Install the 6 mm shank cutter into a properly secured collet or tool holder rated for the intended spindle speed. Select cutting parameters according to the material: moderate speeds and feeds for steel and stainless steel, higher speeds and lighter cuts for plastics to avoid melting. Use appropriate coolant or air blast when machining metals to manage heat and chip evacuation. Verify runout and tool clamping before starting the operation and make test passes to confirm dimensions and surface finish.

What to consider before purchase

• Material types you will machine (steel, stainless steel, plastics) and required cutting performance
• Compatibility with your machine’s collet or tool holder for a 6 mm shank
• Whether required tasks are general-purpose or need specialised tooling (coatings, diameters, insert types)
• Expected production volume and whether tool life of standard cutters meets your needs

Usage recommendations

For best results, match spindle speed and feed to the workpiece material, use appropriate coolant when cutting metals, and inspect cutters regularly for wear. Replace cutters showing significant flank wear or chipping to maintain part quality and reduce rework.
