The 3M diamond resin wheel 644BI is a general purpose wheel designed for the production and re-sharpening of tungsten carbide tipped saw blades. This wheel offers high material removal rates and good form retention. Designed for precision resin bonded diamond wheels are designed for high performance when grinding on materials such as tungsten carbide. The 3M diamond resin wheel 644BI line is specifically designed for the production and re-sharpening of tungsten carbide tipped saw blades. This application requires the highest level of quality which the 3M diamond resin wheel 644BI provides. High quality bonding these super abrasive wheels also use a resin bonding which are specially designed to resist thermal and chemical deterioration, which can occur during high speed grinding. This O hardness rated bond delivers high material removal rates with good form retention when grinding materials such as tungsten carbide. Water-based coolant is required for this wheel. The right wheels for the job 3M provides a broad portfolio of super abrasive wheels that cover the full range grinding applications on hard to grind materials. These wheels are available in a variety of sizes, shapes, core materials and arbor holes custom bore to fit customer specifications. From short runs and re-sharpening to "lights-out" and long production runs, 3M has the wheel design to meet your needs.
