3M Diamond Lapping Film 668X, PSA Sheet, 1 Micron, 9" x 11", 10/CT

A steady finish when the work has to come out right.

Consistent results on hard materials, without the fuss.

Product Overview:

When the surface has to look clean and feel even, this diamond lapping film keeps the job simple. It uses precisely graded diamond particles on a polyester film, so you get a repeatable finish instead of guesswork. That matters when you are working with extremely hard materials and need the same result again and again. It is a PSA version of the 661X product, which makes setup straightforward. Picture the sheet doing its work with a quiet, gritty confidence, then leaving a finish that feels smooth in your hand and reads right under the light.

Key Features:

• Precisely graded diamond particles: They help you keep the cut and finish consistent, so you are not chasing surprises.
• Polyester film backing: It gives the sheet a steady base, which helps the work stay controlled and feel less slippery.
• PSA sheet format: The pressure sensitive adhesive makes setup easy, so you can set this in place and get moving.
• Built for extremely hard materials: It handles demanding surfaces with a calm, even touch that saves you from rework.
• 1 micron grade: Fine enough for a refined finish when you want the surface to look clean and feel true.
