Which Is The Best 3M Aluminum Oxide Sandpaper

This lapping film is made in the USA by 3M (TM). These microfinishing lapping sheets were developed for industrial applications and can be used to flat lap or polish just about anything. This lapping film contains carefully graded aluminum oxide particles that are electrostatically coated onto a high strength polyester film backing. This fast cutting, water resistant abrasive provides precise, consistent, close tolerance finishes, and are available in a wide range of precise micron grades to meet any sharpening or polishing need. They can be affixed to a hard flat surface (usually 1/4 inch glass) and used to get a scary sharp edge on wood chisels or plane irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can also be used to put a fine polish on jewelry or gem stones. These are PSA and have pressure sensitive backing. They have a 3 mil high-strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper. The sheets are not marked so using their color is the only accurate way to identify them. These Aluminum Oxide (AO) sheets come in the following grades: 1) 0.3 micron (white) or 60.000 grit 2) 1 micron (light green) or 14,000 grit 3) 3 micron (pink) or 8,000 grit 4) 9 micron (light blue) or 1800 grit 5) 12 micron (yellow) or 1200 grit 6) 30 micron (green) or 600 grit and 7) 40 micron (blue) or 300 grit. The sheets are not marked so using their color is the only accurate way to identify. In the finer grits, it can be difficult to differentiate the abrasive side from the backing. The abrasive side will always have a matte finish, where the film backing side will be glossy.
