3M™ Microfinishing Film Roll 268L, 30 Mic 3MIL, Type D, Unbacksized,Config

The 3M™ Microfinishing Film Roll 268L features precision, micron-graded aluminum oxide, resin-bonded to a high-strength, polyester film backing to produce a fast cut-rate and precise, uniform finish on wood, solid surface composites, plastic, fiberglass, metals and in paint preparation. The film backing offers flexibility without sacrificing durability and reliable performance. To complement the effective abrasive action, the polyester film backing offers greater tear-resistance than comparable paper products, making it ideal for high-production environments.

3M™ Microfinishing 268L film products are constructed with aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

Coolant generally extends abrasive life, increases cut rate, prevents loading, and reduces air-borne particles. The high-strength, bare-film backing maintains its strength and flexibility when run wet, while paper will disintegrate. Available in a range of grades to help operators achieve goal tolerances.
