Maykestag Solid Carbide Corner Radius End Mill 16mm R1.5 Speedcut Universal ALUNIT-S
Professional 16mm Speedcut Universal solid carbide corner radius end mill with a precise 1.5mm 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 16mm version combines solid carbide construction with a 1.5mm corner radius, a relieved neck and four cutting flutes, creating a highly rigid 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 1.5mm radius on this 16mm cutter provides a generous internal radius while reinforcing the cutting corner, making it particularly useful for profiling, shoulder milling and contoured machining where smooth transitions, dimensional accuracy and cutting-edge strength are important.
