3M™ 7010495983 650HJ Wheel, 4 in Dia x 1/4 in THK, 1-1/4 in Hole, D220 Grit, Diamond Abrasive

The 3M™ diamond wheel 650HJ is used to generate the flute which is the helical or straight groove in the body of the cutting tools made from tungsten carbide. This hybrid bonded wheel offers high cut rates, good form retention and increased thermal stability during higher temperature grinding operations. High quality flute grinding, the 3M™ diamond wheel 650HJ line is specifically designed for the production of tungsten carbide cutting tools. The wheel is used to generate the flute which is the helical or straight groove in the body of the tool. This process requires the highest level of quality that the 3M™ diamond wheel 650HJ provides. The 3M™ diamond wheel 650HJ line uses a hybrid bond system which offers increased thermal stability compared to the phenolic or polyimide bond systems. This allows 650HJ to grind at higher cut rates and maintain form under higher temperature grinding conditions where phenolic and polyimide bond systems undergo thermal and chemical deterioration. The right wheel for every job, 3M™ provides a broad portfolio of super abrasive wheels used for your round tool relief and clearance angle applications. From short runs and re-sharpening to ''lights-out'' and long production runs, 3M™ has the wheel design to meet your needs.
