3M CBN Polyimide Wheel 164PL is used for grinding primary and secondary relief angles on cutting tools made of tool steel and high speed steel. This general purpose wheel offers high cut rates, increased form holding, and increased thermal stability during higher temperature grinding operations.
Cubic boron nitride (CBN) resin-bonded wheel produces fast cut rates
Designed for better form retention, using water or oil lubricant
Offers thermal stability during high temperature grinding operations for durability
Polyimide bond system provides improved thermal stability during high temperature grinding
