3M 7010492845 | 1.250" Center Hole Diameter x 5.000" Overall Diameter x 0.375" Thickness x 654BI Wheel Type 1A1 Resin Bond Diamond Wheel

The 3M diamond resin wheel 654BI 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-cut rate when used with water-based lubricants.

• Resin bonded diamond wheels are designed for high performance grinding on carbide. The 3M diamond resin wheel 654BI 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 654BI provides.

• These superabrasive wheels also use a resin bonding which are specially designed to resist thermal and chemical deterioration, which can occur during high speed grinding. This P rated bond delivers high material removal rates on materials like tungsten carbide where stock removal is the priority and form retention is less critical. Water-based coolant is required when using this wheel.

• 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.

Features:

• 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 material removal rates for applications where stock removal is the priority
• Various wheel designs are available for gashing, primary and secondary relief and end work
• Arbor holes are made to customer specifications
