DoAll of De Plaines, Ill., has unraveled a band saw blade that is harder and tougher than conventional bi-metal blades. With a finer grain size than M-42 cobalt and a higher percentage of ultra-hard metallic carbides more evenly distributed, the company has achieved a 70 Rc tooth tip hardness, as compared to an industry standard of 68 Rc These novel bi-metal blades have delivered as often as 30% more blade life during on-site testing at production saw workshops
DoAll uses a proprietary proces to band the wire made from dusted metal to coils of high-strength, spring-steel
