3M 661X Diamond Lapping Film, 0.10 Micron, 3" x 6", 25/PK, 250/CT

A fine finish that stays even from sheet to sheet.

Good for hard materials when you want the cut to feel clean and controlled.

Product Overview:

For diamond lapping film, this one keeps things steady. The 3M 661X gives you a precise 0.10 micron sheet, so you are not guessing at the finish. It uses diamond particles on polyester film, and that setup is built for hard materials that need a consistent touch. In a shop where the work has to look right and feel right, that matters. You can picture the surface coming out smooth, almost glassy, with less fuss between passes. It is a small sheet, sure, but it carries a lot of control. Set it in place and you get a repeatable result without the usual wobble.

Key Features:

• Precisely graded diamond particles: They give you a tight, even cut, so each pass stays on track. Notice the steadier feel right away.
• Polyester film backing: It supports the abrasive evenly, which helps the sheet stay firm and work cleanly.
• 0.10 micron grade: That fine grit is made for a detailed finish when you need the surface to come out crisp.
• Made for extremely hard materials: It handles the tough stuff without turning scratchy or uneven, which saves a bit of grief.
• 3 in x 6 in sheet size: The compact format gives you a tidy work area and easy handling in close setups.
• Available in several grades: If your process calls for a different finish level, the line runs from 0.10 to 30.0 micron.
