Maykestag VHM Speedcut 4.0-Inox HPC End Mill 3mm Long Series 4 Flute Ultradur

Maykestag VHM Speedcut 4.0-Inox HPC End Mill 3mm Long Series

Professional 3mm solid carbide HPC end mill from the Maykestag Speedcut 4.0-Inox range, featuring a long necked design, four cutting edges, unequal 39°–42° spiral angles and ULTRADUR coating for high-performance machining, with particular strength in stainless steel applications.

The Maykestag Code 8347 Speedcut 4.0-Inox is a high-performance solid carbide end mill designed for demanding milling operations where cutting stability, chip control and dependable tool life are required. This 3mm cutter features a relieved 2.80mm neck diameter with a 20mm neck length, providing additional reach and clearance around the cutting section. Its four-flute geometry and unequal spiral angles help produce a smooth and controlled cutting action, while the application profile is particularly strong in stainless steels.

What is an HPC end mill? HPC refers to High Performance Cutting. An HPC end mill uses optimised cutting geometry to support productive milling at suitable cutting speeds and feed rates. On the Speedcut 4.0-Inox Code 8347, the combination of solid carbide construction, unequal 39°–42° spiral angles, a necked long-series design and ULTRADUR coating is intended to provide stable cutting performance in demanding machining applications.
