3M Diamond Lapping Film 664X, PSA Sheet, 45 Micron, 3 in x 8 in, 25/Inner, 250/Case

A steady finish when your lapping work needs a clean, even touch.

PSA backing keeps the sheet easy to set and hold in place.

Product Overview:

Diamond lapping film is one of those small-shop details that pays off fast. This 3M 664X sheet gives you a PSA face for quick placement, then stays put while you work through flat lapping. The stronger resin system adds toughness and helps the sheet last longer, which is a nice thing when you are trying to keep the line moving and not fuss with flimsy stock. At 45 microns, it gives you a middle-ground cut that feels measured, not wild. Picture a smoother surface, a steadier hand, and less scrap on the bench. That is the kind of calm you notice right away.

Key Features:

• PSA backing: Lets you set the sheet fast on a flat surface, so you can get to work without the usual fiddling.
• Strong resin system: Holds up under repeated use and gives the film a sturdier feel in your hand.
• 45 micron grade: Lands in a practical middle range, giving you controlled lapping without going too coarse or too fine.
• Flat lapping use: Suits jobs where you want even contact and a steady finish across the full work area.
• 3 in x 8 in sheet size: Fits neatly into small setups and makes it easier to work with compact parts.
