3M 661X Diamond Lapping Film, 6.0 Micron, 4.5 x 4.5 in, 25/Inner, 250/Case

A steady finish when the job calls for a fine touch.

Diamond lapping film that keeps the work calm and consistent.

Product Overview:

When you need a finish that stays true, this 3M diamond lapping film gives you a clean, even bite on hard materials. The film carries precisely graded diamond particles on polyester, so the cut feels controlled, not twitchy. That matters when you are chasing repeatable results and do not want to fuss with a half decent workaround. It suits shops that care about detail, and yes, the little sheet format is handy when the task is fussy. Set it in place and you get a smoother path toward a consistent finish, with less guessing and fewer ugly surprises.

Key Features:

• Precisely graded diamond particles: They give you a steady cut on extremely hard materials, so the finish stays even from pass to pass.
• Polyester film backing: The sheet holds its shape well, and you can feel the control when the work gets picky.
• 6.0 micron grade: Fine enough for careful work, with the kind of repeatability that saves you from redoing the same spot twice.
• 4.5 in x 4.5 in sheet size: Small and square, it fits neat little setups where a full sheet would be a bit clumsy.
• 25 per inner, 250 per case: You get a practical pack count for ongoing use, which makes restocking one less thing on your plate.
