3M Diamond Microfinishing Film 675L Sanding Belts – 1" x 10-1/2" | 20 & 30 Micron

3M Diamond Microfinishing Film 675L Abrasive Belts – 1" x 10-1/2"

Achieve exceptional precision, efficient material removal, and professional-quality finishing with 3M Diamond Microfinishing Film 675L Abrasive Belts. Designed for demanding sanding and polishing applications, these premium diamond abrasive belts provide aggressive cutting performance while delivering controlled, consistent surface refinement.

Unlike conventional abrasives, the 3M Diamond Microfinishing Film 675L offers an exceptionally effective cutting action, allowing users to begin with a finer micron grade than normally required while still achieving efficient material removal. This helps reduce the number of finishing steps needed to achieve a smooth, uniform surface.

These versatile diamond abrasive belts are suitable for working with a variety of materials, including stone, metal, enamel, glass, and fiberglass, making them an excellent choice for jewelry fabrication, lapidary work, precision metalworking, and specialized finishing applications.

For optimal performance, use with water or Bur Lube to help extend abrasive life and improve finishing results. Moderate to light pressure is recommended to maintain effective cutting action and consistent surface quality.

Each belt measures 1 inch wide by 10-1/2 inches long and is available in 20 and 30 micron grades for controlled sanding and fine surface refinement.

Key Features:

• Premium Diamond Abrasive: High-performance diamond microfinishing film provides aggressive cutting action and consistent surface refinement.

• Efficient Material Removal: Allows users to begin with a finer grade than conventional abrasives because of its aggressive cutting performance.

• Precision Finishing: Produces smooth, uniform surfaces on a variety of hard and demanding materials.

• Versatile Material Compatibility: Suitable for stone, metal, enamel, glass, and fiberglass.

• Two Micron Grades: Available in 30 and 20 micron for progressive surface finishing.

• Extended Abrasive Life: Using water or Bur Lube helps reduce loading and extend the useful life of the abrasive.

• Controlled Cutting Action: Designed for effective performance with moderate to light pressure.

• Convenient Belt Size: Measures 1" wide x 10-1/2" long for compatible belt sanding equipment.

Available Micron Grades:

• 30 Micron (Fine): Ideal for initial fine sanding, scratch reduction, surface leveling, and preparing materials for further finishing.

• 20 Micron (Extra Fine): Designed for finer surface refinement, reducing sanding marks, and preparing surfaces for polishing.

Ideal Applications:

• Jewelry making and precision metal finishing

• Stone and lapidary finishing

• Enamel surface refinement

• Glass sanding and finishing

• Fiberglass surface preparation

• Scratch removal and surface smoothing

• Fine sanding of hard materials

• Preparing surfaces for polishing

• Professional jewelry fabrication and repair

Recommended Use:

1. Install the abrasive belt on compatible belt sanding equipment.

2. Apply water or Bur Lube as appropriate for the material and equipment.

3. Use moderate to light pressure during sanding.

4. Begin with 30 micron for initial fine finishing or 20 micron when only light surface refinement is required.

5. Progress to additional polishing steps as needed to achieve the desired finish.
