MAYKESTAG Speedcut 4.0-Inox Solid Carbide HPC End Mill 8mm Long Series 3 Flute

Maykestag Speedcut 4.0-Inox Solid Carbide HPC End Mill 8mm

Professional 8mm 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.

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 8mm cutter has a 0.10mm chamfer at 45° at the cutting edge.

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.
