Band saw Blade efficiency was limited prior to the advent of bi-metal blades. The band saw blade used to be made entirely of high carbon steel because it was pliable enough to withstand the stress caused by its winding path around the band saw machine’s drive wheels and through the saw blade guides. Because it was necessary to use a softer, more flexible backing material, manufacturers were prevented from capitalizing on the sawing efficiency that could be gained by using a harder material that would provide a more durable tooth edge.

Carbide-tipped band saw blades changed band sawing tremendously and permanently. Since then, advancements in tooth configurations, tooth geometry, edge materials and backing steels, in addition to improved methods for welding carbide-tipped teeth, have continued the band saw blade’s march toward increased productivity and blade life at a relatively steady pace.

Under this condition, the CBN Grinding Wheels and Diamond Grinding Wheels could be used, such as the shape of 6A2, 12A2, 12V2, and 11V9.
