NORaX Flex U242 engineered abrasive polishing belts, with their multi-layered, consistent surface pattern outlast conventional abrasive belts with 2- 5 times longer life. They produce repeatable, uniform finishes from the first to last part. Inside each pattern are precisely graded abrasive particles to prevent wild scratches, and a grinding aid to keep your parts cool. Longer product life, higher quality finishes, faster cut rates, and the ability to skip finishing steps all help drive down the costs of your finishing processes.
