The 3M CBN Polyimide Wheel 184PN 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. The polyimide bond wheel construction offers excellent form retention and increased thermal stability under higher temperature grinding operations.
Arbor holes are made to customer specifications, so you get exactly the size you need
Cubic boron nitride abrasive mineral provides fast cut rates at high temperatures
Excellent form retention and long life
For use with either oil or water coolants
The polyimide bond system provides improved thermal stability during high temperature grinding operations when compared to phenolic resin bonds
Used for flute grinding on high speed steel, tool steels, and ferrous metals
