3M (TM) Diamond Lapping Microfinishing Film 3 x 8" PSA Back (6 micron 3200 Grit)

Description

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.
These 3M (TM) diamond microfinishing lapping sheets were developed for the electronic industry but are the perfect solution to flat lapping, polishing or sharpening just about anything. 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 really excel when used on harder materials such as hardened steel, carbide or gemstones. This diamond film is the most aggressive polishing or sharpening media available and will cut up to twice as fast as aluminum oxide (AO) or silicon carbide (SC) films. The diamond particles have superior fracture resistance and will outlast other lapping and sharpening media by up to two times. They are available in a wide range of precise micron grades from .1 micron (200,000 grit) to 125 micron (120 grit) to meet any sharpening or polishing need. They can be affixed to a hard, flat surface (usually thick float 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 be used to sharpen carbide cutting tools. They can also be used to put a fine polish on jewelry or gemstones. These sheets 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. When affixing to a substrate make sure to fully clean the surface as any debris will create a bump and expose the film to being sliced. They can be used dry but using wet with water or light oil as a lubricant to carry away the swarf is preferred as this minimizes loading and prolongs the life of the abrasive.
My E-Bay philosophy is simple, you are the customer and you decide how you want to handle the deal. I will go along with most anything as long as it is not too outrageous and you keep me informed. If it will be a few days before you get payment to me, no problem, just let me know so I will not worry about it being lost. I do not have any hard and fast time lines on what happens when. I work very hard to get all packages to the Post Office the next day after I receive payment. If for some reason that will be delayed, I will let you know.
All my items are shipped either USPS 1st class or Priority shipping.  I will ship another method to get it to you faster as long as you and are willing to pay for the faster shipping.
You decide how you want to pay and I will usually go along with it. So far all (well, most) of my dealings have been with nice, honest people. (As I would expect) .
My satisfaction policy is also very simple, you are the customer and you decide if you want the item. Satisfaction is guaranteed, no exceptions. Purchase may be returned for any reason or no reason within 30 days in original condition for a full refund. If the item is defective or for something I did or failed to do, I will also refund the postage. If you just changed your mind or found another one down the street, cheaper or better. I still accept returns except you will need to pay the postage.
