3M 7010497894 | 1.250" Center Hole Diameter x 6.000" Overall Diameter x 1.000" Thickness x 663BI Wheel Type 6A2 Resin Bond Diamond Wheel

The 3M diamond resin wheel 663BI is used in the production and sharpening of carbide cutting tools. This general purpose wheel is designed to give you the best balance of form retention and the free-cutting ability and designed for use with water-based lubricants.

• Resin bond diamond wheels are designed for high performance when grinding tungsten carbide. The 3M diamond resin wheel 663BI line is specifically designed for the production and re-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 663BI provides.

• These superabrasive wheels also use a resin bond which is specially designed to resist thermal and chemical deterioration, which can occur during high speed grinding. This R rated bond provides cut rate without sacrificing form retentionwhile grinding materials like tungsten carbide.. This bonding material is used with water based lubricants for lower grinding temperatures.

• 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.
