This is a highly innovative and excellent performing solid carbide end. Features variable pitch chipsplitter combination. Noted for its 4- and 5-flutes with the helix angle 38° and large corner radii delivers stronger cutting edge. It is highly useful in cavity milling and heavy roughing cuts. The performance of serrated cutting edge delivers better surface finish when compared to competitor models. Enables chatter-free milling. The diameters of the tool vary from .250" to .750".
