3M Hookit Microfinishing Film Disc 268L is a fast-cutting abrasive for precise, uniform, close-tolerance finishes. An aluminum oxide mineral is resin-bonded to a 3 MIL, high-strength polyester film backing for durability.
The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or plowing like conventional abrasives, resulting in a disc that cuts up to 2x faster than conventional abrasives.
Maximum Speed 10000 rpm. Manufacturer: 3M. We chose aluminum oxide abrasive, which is a popular choice among industrial professionals because of its fast cut-rate and long life. Due to their fast cut-rate, hardness, strength, and low heat retention, they are widely used in grinding applications in addition to sanding and finishing applications.
