End Mill / Roughing

Roughing End Mills

Roughing Mill

Roughing end mills have scallops on the outside diameter which causes the metal chips to break into smaller segments.  This results in lower cutting pressures at a a given radial depth of cut.  They are mainly used to rough mill the material off when large amounts of material are removed.  They come in carbide, cobalt, and HSS substrates, and are often PVD coated with AlTiN or ZrN.  They come in fine, medium and coarse pitch scallops.  They come in stub, standard, long, and extra long lengths.  There are many different helix angles, and flute configurations, because of the many different materials being milled.
