3M 7000027556 Diamond Lapping Film Roll 30.0 Micron 8x50ft

Product Description

The 3M 7000027556 is a diamond lapping film supplied in roll form, engineered for precision material removal and surface finishing in industrial and trade applications. Built on a reinforced resin system, this film delivers added toughness and extended service life compared to standard lapping films. The 30.0 micron grade targets superfinishing, roll polishing, and flat lapping operations where consistent cut rate and surface quality are required. At 8 inches wide and 50 feet long, the roll format suits both automated and manual finishing setups. Licensed trades and precision machinists rely on this product for tight-tolerance surface preparation work.

This diamond lapping film is used primarily in superfinishing, roll polishing, and flat lapping applications across industrial manufacturing, toolroom, and precision finishing environments. The 30.0 micron grade is suited for intermediate to fine stock removal stages where surface finish consistency matters. It is also available in 45.0 and 60.0 micron grades for coarser cut requirements in the same application types.

Key Features

• Reinforced resin system provides added toughness and longer film life
• 30.0 micron diamond abrasive grade for precision superfinishing and flat lapping
• Roll format: 8 inches wide by 50 feet long for continuous feed or cut-to-length use
• Suitable for superfinishing, roll polishing, and flat lapping operations
• Available in multiple micron grades: 30.0, 45.0, and 60.0 micron

Compatibility

Designed for use in superfinishing, roll polishing, and flat lapping applications. Verify that lapping machine platens, roll polishing fixtures, or flat lap surfaces accept an 8-inch-wide roll film format before installation.

Installation Notes

Installation and setup should be performed by qualified machinists or precision finishing technicians familiar with lapping and polishing equipment. Power down and lock out all rotating equipment before loading or changing the film roll. Ensure the roll core seats securely on the 3-inch core spindle and that film tension is set per the equipment manufacturer's guidelines. Do not exceed the equipment's rated speed or contact pressure for the film grade in use.
