The 3M™ Microfinishing Film Roll 373L quickly cuts, shapes, and polishes, delivering uniform, close-tolerance finishes on parts used in metalworking applications.
The 3M™ Microfinishing Film Roll 373L has a friction coating made with quartz mineral. This coating is anti-slip, so the abrasive won't slip from machines or workpieces like camshafts, crankshafts, and transmission parts, during finishing. The polyester cloth backing is strong and can be run wet on microfinishing machines, remaining strong when applied to the oscillating part. Additionally, the abrasive mineral is uniformly distributed over the backing. The strength of the backing, combined with the uniformity of the mineral, helps produce a consistent finish each time you sand.The 3M™ Microfinishing Film Roll 373L with Type 2 film was designed in a range of colours - reflective of each grade - for added value, helping reduce the risk for error. To improve the geometry of parts and achieve desired finishes, the 3M™ Microfinishing Film Roll 373L is an exceptional choice.
