MAYKESTAG Solid Carbide Corner Radius End Mill 3mm R0.3 Speedcut Universal ALUNIT-S

Maykestag Solid Carbide Corner Radius End Mill 3mm R0.3 Speedcut Universal ALUNIT-S

Professional 3mm Speedcut Universal solid carbide corner radius end mill with a precise 0.3mm corner radius, long-series neck-relieved design, 4 flutes, unequal 35°–38° spiral angles and ALUNIT-S® coating for high-performance milling.

The Maykestag Code 6447 Speedcut Universal is a precision HPC milling cutter designed for productive machining across a broad range of engineering materials. This 3mm version combines a solid carbide cutting body with a 0.3mm corner radius, a relieved neck and four cutting flutes, providing a strong and stable cutting geometry for accurate profiling, contouring, shoulder milling and other precision milling operations.

Its unequal 35°–38° spiral geometry provides a progressive cutting action, while the long-series neck-relieved construction gives additional clearance behind the cutting section. The cutter is manufactured to DIN 6527 L, features a cylindrical DIN 6535-HA shank and is finished with Maykestag&s ALUNIT-S® coating.
