Maykestag Speedcut 4.0-Inox ULTRADUR HPC Solid Carbide End Mill 9mm
High-performance 9mm long-series solid carbide end mill from the Maykestag Speedcut 4.0-Inox range, featuring four flutes, unequal 39°-42° spiral angles, a 0.25mm 45° corner chamfer, ULTRADUR coating and a DIN 6535-HB shank. Designed especially for stable, productive milling in stainless steel and other suitable engineering materials.
The Maykestag Code 8747 Speedcut 4.0-Inox is an HPC solid carbide end mill developed for demanding CNC milling applications where process stability, surface quality and dependable cutting performance are important. This 9mm version uses four cutting flutes together with unequal spiral angles of 39°-42°. Varying the spiral geometry helps interrupt repetitive cutting forces, supporting smoother running and helping reduce vibration during demanding milling operations.
The cutter is manufactured from VHM solid carbide and protected with Maykestag’s ULTRADUR coating. Its long-series DIN 6527L geometry provides additional reach, while the precision DIN 6535-HB shank incorporates a driving flat for secure clamping in compatible tool-holding systems. The 9mm cutter has a 10mm shank, 72mm overall length, 19mm cutting length and four cutting edges.

Why Choose Maykestag?
Maykestag is an Austrian cutting-tool specialist focused on precision-manufactured tooling for professional machining. With high-performance cutters, small details such as flute geometry, dimensional tolerances, tool material and coating all work together. That attention to detail is especially valuable in demanding materials such as stainless steel, where stable cutting conditions can make a noticeable difference to tool life, productivity and surface quality.
The Code 8747 Speedcut 4.0-Inox ULTRADUR series combines solid carbide construction, ULTRADUR coating, four flutes and unequal 39°-42° spiral angles in a long-series HPC cutter. For the 9mm size, Maykestag specifies a 10mm HB shank, 19mm cutting length and a precision 0.25mm corner chamfer.
Designed for High-Performance Stainless-Steel Milling
Stainless steel can be demanding to machine because stable cutting, controlled heat generation and consistent chip formation all matter. The Speedcut 4.0-Inox geometry is designed around these requirements. Its unequal spiral angles help reduce the tendency for repetitive cutting forces to develop, while the four-flute configuration provides a balanced and productive cutting action. Used with the correct cutting speed, feed, tool holding and machining strategy, the cutter is designed to provide a smooth, controlled machining process with dependable surface quality.
