KTC HSS End Mill



End Mill Cut Varieties
Centre-cutting end mills are those that can be plunged straight down into the material. They can mill, and they can drill. (They have cutting edges on the end face and the sides) These are usually the 2 flutes or 3 flute endmills, and occasionally you can find some 4 flutes that are centre cutting as well.
Non-centre cutting end mills refers to those that mill, they do not drill. (they have cutting edges only on the sides)
Up-cut end mills eject chips towards the top of the workpiece, leaving a cleanly cut bottom surface inside your material.
Down-cut end mills do the opposite, they leave a smooth top surface on your material.
Compression end mills combine the best of both worlds and produce a smooth surface on both ends of the workpiece when cutting.



HSS550TC end mill cutters are made of M42 HSS,which is with low vanadium content (around 1%) and high cobalt content (≤8%). This series of cutters are normally used for hard-cut materials, such as ordinary medium and low carbon steel, alloy steel and other materials processing.
