3M 661X Diamond Lapping Film, 3 Micron, 9" x 11", 10/CT, 100/CS

A steady finish when the work needs a clean, exact touch.

Fine grit for a calm, repeatable result.

Product Overview:

When you are chasing a cleaner edge, this 3M diamond lapping film gives you a sure hand. The film carries precisely graded diamond particles, so the cut feels steady instead of fussy, and the finish stays consistent from sheet to sheet. It suits hard materials that do not give up easily, which saves you from that stop and start grind. In a shop where the hum never quite stops, that kind of predictability matters. Set it in place, work through the pass, and you can picture the surface coming out even, smooth, and ready for the next step.

Key Features:

• Precisely graded diamond particles give you a controlled bite, so each pass stays even and on target.
• Polyester film backing holds its shape well, which helps the sheet lie flat and work cleanly.
• Built for extremely hard materials it handles stubborn surfaces with less fuss, and that is a relief.
• Consistent repeatable finish lets you compare results from one sheet to the next without guesswork.
• 3 micron grade gives you a fine finishing step when you want a more polished, measured touch.
