3M™ Resin Bond Diamond Wheels and Tools, 4A2P, 8X3/8X3/4, X=1/16, W=1/4 D180 644BI - MMMRBDW34759

Designed for Precision
Resin bonded diamond wheels are designed for high performance when grinding on materials such as tungsten carbide. The 3M™ Diamond Resin Wheel 644BI line is specifically designed for the production and re-sharpening of tungsten carbide tipped saw blades. This application requires the highest level of quality which the 3M™ Diamond Resin Wheel 644BI provides.

High Quality Bonding
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 O hardness rated bond delivers high material removal rates with good form retention when grinding materials such as tungsten carbide. Water-based coolant is required for this wheel.

The Right Wheels for the Job
3M provides a broad portfolio of superabrasive wheels that cover the full range grinding applications on hard to grind materials. These wheels are available in a variety of sizes, shapes, core materials, and arbor holes custom bore 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.
