3M™ diamond wheel 665HL is used in the production and sharpening of carbide cutting tools. This general purpose wheel is designed to give you the best form retention and a long wheel life without sacrificing cut rate. It can be used with either oil or water based lubricants. High performance grinding hybrid diamond wheels are designed for high performance grinding on carbide. The 3M™ diamond wheel 665HL line is specifically designed for the production and sharpening of cutting tools, including end work, gashing and cutting primary and secondary relief edges. Primary relief involves removing material directly behind the cutting edge to enhance chip clearance. For secondary relief, as light bevel is ground next to the primary relief. End work grinds a small relief angle on the tip of the tool, while gashing adds a slot along the cutting face to allow for chip flow. Each of these processes require the highest level of quality that the 3M™ diamond wheel 665HL provides. Hybrid bonding system the 3M™ diamond wheel 665HL line uses a hybrid bond system which offers increased thermal stability compared to the phenolic or polyimide bond systems. This allows 665HL 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.
