3M industrial and occupational products are intended, labeled, and packaged for sale to trained industrial and occupational customers for workplace use. Unless specifically stated otherwise on the applicable product packaging or literature, these products are not intended, labeled, or packaged for sale to or use by consumers (e.g., for home, personal, primary or secondary school, recreational/sporting, or other uses not described in the applicable product packaging or literature), and must be selected and used in compliance with applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI), as well as all product literature, user instructions, warnings, and other limitations, and the user must take any action required under any recall, field action, or other product use notice. Misuse of 3M industrial and occupational products may result in injury, sickness, death, or property damage. For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.

Designed for Polishing and Finishing

The 3M Microfinishing Film Roll 272L is specifically designed for a wide range of microfinishing applications. It is suitable for tasks such as cylindrical and centerless grinding, finishing, and roll superfinishing. Additionally, it is an excellent choice for automotive powertrain components that require a flexible abrasive to access hard-to-reach areas. The roll format of the 272L offers great flexibility, allowing it to be easily cut and shaped to fit the dimensions of your specific part or project. It can be used by hand or with microfinishing machines.

Engineered with Aluminum Oxide Mineral

3M engineers have developed the 3M Microfinishing Film Roll 272L by anchoring aluminum oxide mineral to a polyester film backing using resin. Aluminum oxide is a popular choice among industrial professionals due to its fast cut rate and long life. The hardness, strength, and low heat retention of aluminum oxide ensure that the roll can withstand wear and tear effectively.

Water-Resistant Polyester Backing

The 3M Microfinishing Film Roll 272L features a 5 mil polyester backing. Film backed abrasives are known for their flexibility, incompressibility, and caliper consistency, making them ideal for microfinishing operations. The roll is equipped with an anti-slip or friction coating on the back, which prevents slippage during the microfinishing application, ensuring consistent results from part to part.

The polyester material used in the roll makes it water resistant, allowing it to be used wet or dry. Applying a lubricant like water can help wash away unwanted swarf and debris, preventing clogging and premature dulling of the mineral. This feature is particularly useful when working with dust-generating substrates. The resin bond that fastens the aluminum oxide to the backing also helps keep the abrasive cool, as it gradually breaks down and dissolves during rotation.

Available in a Range of Grades

The 3M Microfinishing Film Roll 272L is available in a versatile range of grades, ranging from 9 to 100 micron. This allows operators to select the appropriate grade for their specific application. Higher grades, such as 100 micron, are suitable for tougher applications that require coarser finishes. On the other hand, lower grades, like 9 micron, are ideal for achieving softer, finer finishes. To minimize the risk of error when using multiple grades in a sequence, each grade is color-coded for easy identification.

The Benefits of 3M Microfinishing Abrasives

The 3M Microfinishing Film Roll 272L offers numerous benefits, including the ability to quickly remove traverse marks and feed lines, eliminate chatter, follow existing geometry, and achieve the desired Ra (roughness average). These qualities make it a preferred choice in various industries, ranging from metalworking to woodworking.
