3M 661X Diamond Lapping Film Sheet, 3.0 Micron, 4.5" x 4.5", 25/PK, 250/CS

Fine finishing that stays steady from sheet to sheet.

It gives you a clean, repeatable finish on hard materials without a fuss.

Product Overview:

When you need a finish you can trust, this 3M diamond lapping film keeps things even. The 3.0 micron coating uses precisely graded diamond particles on a polyester film, so the work feels controlled instead of gritty. That matters when you are smoothing tough surfaces and want the same result every time, not a lucky break. It fits right into shops that care about detail, whether you are tuning parts or chasing a clean final pass. Picture the surface coming together with less guesswork and a smoother handoff to the next step.

Key Features:

• Precisely graded diamond particles: They give you consistent cutting action, so the finish does not wander around on you.
• Polyester film backing: It stays stable in use and helps the sheet lay flat while you work.
• 3.0 micron grade: It suits fine finishing work when you want a tighter, more polished result.
• Sheet size: At 4.5" x 4.5", it gives you a handy square format that is easy to handle.
• Wide grade range: Available from 0.10 to 30.0 micron, so you can match the finish to the job at hand.
