Maykestag Speedcut 4.0-Inox Solid Carbide HPC End Mill 2.5mm Long Series 3 Flute

Maykestag Speedcut 4.0-Inox Solid Carbide HPC End Mill 2.5mm

Professional 2.5mm Speedcut 4.0-Inox HPC end mill manufactured from solid carbide, featuring a long neck-relieved design, three cutting flutes, unequal 45°-48° spiral angles and Maykestag ULTRADUR coating for high-performance milling across demanding materials, with particularly strong suitability for stainless steels.

The Maykestag Code 8107 Speedcut 4.0-Inox is a high-performance solid carbide milling cutter developed for controlled, efficient machining where rigidity, cutting-edge stability and dependable chip evacuation are important. Its long-series, neck-relieved construction provides additional working clearance around the cutting section, while the three-flute geometry combines cutting performance with sufficient flute space for chip removal. Different spiral angles of 45°-48° are used across the cutting edges, helping to produce a smoother cutting action during demanding milling operations.

What is an unequal-helix HPC end mill? An unequal-helix end mill uses slightly different spiral angles on its cutting flutes instead of repeating the same helix on every edge. This helps interrupt repetitive cutting forces that can contribute to vibration during milling. HPC, or High Performance Cutting, describes a cutter geometry developed for productive machining under suitable machine, workholding, speed and feed conditions. Product highlights

• Solid carbide construction: VHM solid carbide provides high rigidity, wear resistance and dimensional stability for precision milling.
• Speedcut 4.0-Inox design: High-performance milling geometry developed with particularly strong application suitability for stainless steels.
• Three cutting flutes: Provides a balanced combination of cutting-edge engagement, tool strength and chip evacuation.
• Unequal spiral angles: Different 45°-48° spiral angles help break up repetitive cutting forces during machining.
• Long neck-relieved design: The reduced neck diameter provides additional clearance behind the cutting section for improved access during deeper profiling and shoulder-milling operations.
• ULTRADUR coating: Maykestag's specified coating for the Code 8107 series supports wear resistance during demanding machining applications.
• Type N geometry: Catalogue-designated Type N cutting geometry for the Speedcut 4.0-Inox range.
• DIN 6535-HB shank: Cylindrical shank with driving flat for secure tool holding in suitable milling systems.
• 45° corner chamfer: This 2.5mm cutter has a 0.05mm chamfer at 45° at the cutting edge.

Why Choose Maykestag?

Maykestag is an Austrian cutting-tool brand focused on precision-manufactured tools for professional machining. Milling performance depends heavily on cutting geometry, carbide quality, dimensional accuracy and consistent tool manufacture, particularly where small-diameter cutters are used at demanding cutting conditions.

The Code 8107 Speedcut 4.0-Inox series combines solid-carbide construction, a three-flute unequal-helix design, neck relief and ULTRADUR coating. The result is a specialised HPC cutter intended for workshops, toolrooms and production environments requiring controlled, repeatable milling performance across steels, stainless steels and other rated materials.

Designed for High-Performance Stainless-Steel Milling

The Speedcut 4.0-Inox geometry is particularly well suited to stainless-steel machining, with Maykestag assigning the Code 8107 series its highest 4/4 application rating for both stainless steels below and above 850 N/mm². The combination of three flutes and unequal 45°-48° spiral angles promotes a controlled cutting action, while the neck-relieved long-series design provides additional clearance around the cutting portion. Correct machine rigidity, workholding, cutting speed and feed selection remain essential for maximising tool life and achieving a consistent surface finish.
