Our 3M™ Diamond Resin Wheel 685BN 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 the fastest cut rate when used with water based lubricants.
These resin bonded diamond wheels are designed for high performance grinding on carbide. The 3M™ Diamond Resin Wheel 685BN 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, a slight 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 Resin Wheel 685BN provides.
High Quality Bonding
These superabrasive wheels also use a resin bond which isspecially designed to resist thermal and chemical deterioration, which can occur during high speed grinding. This T rated bond provides excellent from retention and long wheel life for precision work on tool metals like carbide. This wheel requires a water based coolant .
The Right Wheels for the Job
3M provides a broad portfolio of superabrasive wheels used for your round tool relief and clearance angle applications. They feature a variety of metal cores, including aluminum, steel, composite and copper, and can be cut with custom arbor holes 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.
Diamond abrasive capable of removing stock or grinding forms on tungsten carbide, cemented carbide, and ceramic work pieces
Durable resin bond resists deterioration from heat, extending the life of the abrasive wheel
Designed to provide high form retention for applications where holding workpiece tolerance is the priority
Various wheel designs are available for gashing, primary and secondary relief and end work
