ABSTRACT:
A carbide tipped saw for cutting non-ferrous industrial metals, capable of use on a low-rpm metal sawing machine designed for saws with high-speed steel teeth, has higher hogger teeth alternating around its periphery with lower raker teeth. Each hogger has a cutting edge that is parallel to the saw axis and extends across more than half of the kerf width, defined by the junction of a positively raked front surface with a top surface. Oblique front edges on the hogger are defined by junctions of the front surface with oblique surfaces that lie between the top and side surfaces and face radially and axially outwardly. Each raker removes only side portions of the kerf and has swept-back cutting edges defined by the junctions of its top surface with chamfer surfaces that are negatively raked and face obliquely forwardly and axially outwardly.
