3M™ CBN Wheel 164PK is used to generate the flute which is the helical or straight groove in the body of the cutting tools made of tool steel and high speed steel. This polyimide bonded wheel offers high cut rates, good form retention, and increased thermal stability during higher temperature grinding operations. High Quality Relief Grinding The 3M™ CBN Wheel 164PK line is specifically designed for the production and re-sharpening of high speed steel and tool steels cutting tools. The wheel used to generate the flute which is the helical or straight groove in the body of the tool. This process requires the highest level of quality that the 3M™ CBN Wheel 164PK provides. Built to Take the Heat The 3M™ CBN Wheel 164PK line uses a polyimide bond system which offers increased thermal stability compared to the phenolic resin bond systems. This allows 164PK to grind at higher cut rates and maintain form under higher temperature grinding conditions where phenolic resin bond systems undergo thermal and chemical deterioration. 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.
