3M™ Individual Sheets Diamond Lapping / Microfinishing Film PSA
Compare price from $13.99 ~ $16.99ADVERTISEMENT
Product Details
These diamond sheets contain carefully graded monocrystalline diamond particles electrostatically coated onto a high strength polyester film backing. This super-fast cutting, long-lasting, water resistant abrasive provides precise, consistent, close tolerance finishes, but excel when used on harder materials such as hardened steel, carbide or gemstones. This aggressive polishing abrasive will cut up to twice as fast and last up to twice as long as aluminum oxide (AO) or silicon carbide (SC) films. They are available in a wide range of precise micron grades from .1 micron (100,000 grit) to 125 micron (120 grit) to meet any sharpening or polishing need. These are PSA (Pressure Sensitive Adhesive) backed. Grades from .1 to 30 micron have a 3 mil backing and grades 45 to 125 have a much thicker 5 mil backing. The high-strength polyester film backing is less likely to tear than traditional wet or dry sandpaper.
