Cubic boron nitride mineral provides fast cut rate at high temperatures
Phenolic resin bond is ideal for short production runs where high cut rates are required
Arbor holes are made to customer specifications, so you get exactly the size you need
Best used for grinding tool steel, high speed steel, and ferrous materials
Our resin bonded 3M™ CBN Wheel 185DN 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 Our 3M™ CBN Wheel 185DN 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.
