Diamond Lapping Film With Pressure Sensitive Adhesive 4.25" X 11"

Single half sheets of diamond lapping film available in 80, 60, 45, 30, 15, 9, 6, 3, 1 and 0.5  micron grades. Manufactured with PSA (pressure sensitive adhesive) backing.

Unlike common sandpapers, these industrial sharpening films are designed for cutting metal and have the grit (diamond particles) anchored in a layer of resin. The resin holds the grit to the paper in a very strong bond. You'll notice how they are more durable and last longer than traditional grade papers.

Our Diamond Lapping Film is our most aggressive abrasive film. The extremely hard diamond particles sharpens fast and last longer than any other material. These films comes with pressure sensitive adhesive (PSA) backing and is  a wide range of abrasive grades from 0.5 Micron to 80 Micron, for precise performance.

Sharpo's diamond lapping film have a 3mils thick (.003") backing to make the film less prone to tearing. The adhesive (PSA) backing makes it very easy to use. Simply peel off the paper backing and press it down on glass or other flat, smooth surface. 

The 4.25" X 11" (half sheet) Diamond Lapping Film is a perfect fit for 5" X 12" glass plates

    These films cut beautifully, and very fast. I tried them in front of a tool sharpening class alongside the aluminum oxide films, and while both were effective, the diamond films were significantly faster. Seemed to obtain a polished, sharp cutting edge on my chisels and planes in just a couple passes. They were also very easy to remove from the glass substrate with no residue left behind. They seemed to hold up very well to 2 days of continual use in class. I plan to keep them around for a while to get a better idea of how long they last, but from my initial experience, I imagine they will be with me for a very long time. I'd say they are well worth having in my sharpening kit.

    Early assessment, works great.

    Thought there was a quality control issue as several felt perfectly smooth. However a good amount of dark swirl quickly appeared.

    Thanks for your review Richard! The nanosize particles can feel very smooth but will do the job!
