The resin bonded 3M™ CBN Wheel 195DM is used for grinding primary and secondary relief angles on cutting tools made of tool steel and high speed steel. This general purpose wheel is designed to provide a fast, free cut, and it is ideal for shorter production runs. High Quality Relief Grinding The 3M™ CBN Wheel 195DM was designed for high performance primary and secondary relief grinding. This process is used in the production and sharpening of cutting tools. Cutting edges are typically "relieved" to enhance chip clearance. Primary relief involves removing material directly behind the cutting edge. For secondary relief, a slight bevel is ground next to the primary relief. The Right Wheel for Every Job 3M provides a broad portfolio of superabrasive 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.
