Resawing veneers requires a wide blade – commonly 2 to 3 inches (52–78 mm) – with a small kerf to minimize waste. Resaw blades of up to 1 inch (26 mm) may be fitted to a standard band saw. Many small and medium-sized sawmills use 1- to 1 + 1 ⁄ 2-inch band saw blades. Timber mills use larger resaws to rip large planks into smaller sizes ...

Carbide-tipped saw blades are widely used to cut wood, plywood, laminated board, plastic, glass, aluminum and some other metals. Solid-carbide saw blades
form and size of the chamfers; The measurement of the cutting edge is performed using a tactile instrument or an instrument using focus variation. To quantify a cutting edge the following parameters are used: cutting edge radius for symmetric edges; cutting edge ellipse axis for asymmetric edges; factor K, this is the relation between Sγ and Sα.
