Blade Break-in

WHY BREAK-IN A BAND SAW BLADE? The band saw blade’s teeth are razor sharp. In order to withstand the cutting pressures of band sawing, the tooth tip should be honed to form a very small edge radius. If a proper break-in procedure has not been performed and the tooth tips are damaged, the blade life, and performance are reduced significantly.
