Confused About Grit Grades? Discover the 3M Lapping Film Standard!

Understanding Grit Grades

Grit grades represent the size of abrasive particles on a lapping film. The finer the grit, the smoother the surface it produces. The 3M Lapping Film Grit Equivalent Table is a useful resource for determining which grit level to use based on microns and intended applications.

How to Use This Table

• Match by Micron if your process specifies surface roughness (Ra/Rz), geometry control, or fiber protrusion levels.
• Match by 3M Product Series if you're looking to replace 3M items like: 261X (Diamond Film), 268X (Aluminum Oxide Film), 466X (Silicon Carbide Film), 372L / 373L (Microfinishing Film Rolls), 598X (SiO₂ for final polish).

Need an Exact Match?

We offer support for:

• Custom cutting to 3M standard disc sizes (e.g., 127mm, 203mm, 305mm).
• Same PET thickness (3mil, 5mil, 7mil).
• Same backing (PSA or plain).
• OEM printing and packaging (logo, barcode, grit code).
• Custom hole patterns (center hole, tab notch).
