Maykestag Solid Carbide Corner Radius End Mill 6mm R2 Speedcut Universal ALUNIT-S
Professional 6mm Speedcut Universal solid carbide corner radius end mill with a precise 2mm 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 engineered for productive machining across a broad range of engineering materials. This 6mm version combines solid carbide construction with a generous 2mm corner radius, a relieved neck and four cutting flutes, creating a strong and stable cutting geometry for accurate profiling, contouring, shoulder milling and general precision milling operations.
Its unequal 35°–38° spiral geometry provides a progressive cutting action, while the long-series neck-relieved construction gives valuable clearance behind the cutting section. Manufactured to DIN 6527 L, the cutter features a cylindrical DIN 6535-HA shank and Maykestag’s specified ALUNIT-S® coating.
A corner radius end mill combines the useful flat cutting face of an end mill with a defined radius between the end cutting edge and the outside diameter. The radius removes the fragile sharp corner found on a conventional square-end cutter and creates a stronger cutting-edge transition. The substantial 2mm radius on this 6mm cutter is particularly useful for machining pronounced internal fillets, radiused shoulders and contoured surfaces where a smooth transition and increased cutting-edge strength are required.
