The carbide tooth tips have a very exact tooth geometry.
Compared to HSS saw blades carbide tipped blades can stand a much higher cutting/ working temperature and therefore a much higher cutting speed and result in smoother cut edges.
Carbide tipped band saw blades are especially recommendable ...
... for cutting very hard and brittle materials, which can not be cut with Bi-Metal or HSS saws.
... for the cutting of all materials in order to raise cutting rates on existing machines.
... in order to reduce cost of the mechanical finishing of the cutting area.
... to use in production lines to reduce idle time during tool changes.
