Electroplated diamond laps

SKU: 50-533


Hi-Tech Diamond electroplated diamond laps provide a flat grinding surface for both rough and fine grinding on stones and glass. Top-grade diamond powder is nickel electroplated uniformly onto a 1mm-thick steel disc. This diamond disc is then professionally bound to an acrylic backing plate, making it ready for use. Because the diamond disc is made of steel, these laps have a long lifespan and are well-suited for more heavy-duty grinding. These electroplated diamond laps are used on our All-U-Need and Slant Cabber lap machines, and can be used on all other lap machines that accept 1/2″ arbors.

6" and 8" diameter laps are available in a large variety of different diamond grits. All laps have 1/2" arbor holes.

Please note: Max RPM is 4,000.

I bought the electroplated 3000 diamond lap disc when I probably should have bought the 3000 grit polishing pad to go with the discs included with my slant lap. I tried it out last night and it didn't seem to do any good and felt odd going from a softer brown, red, then blue disc to this hard metal plate. I felt like it did absolutely nothing. I paid a lot of money for this disc and I don't think I will ever use it again. I used it with the water like the first few discs. Am I using it wrong?

Excellent quality, nicely balanced with no vibration. I bought his for grinding a piece of black granite, and it did great!


Excellent quality laps!!
The adhesive on one allowed the disk to slide on the backing plate but I was able to deposition it with no further issues.

8" 80 grit

Had the 180 grit wheel but bought the 80 grit and it seems to speed up the process a bunch . Was just what I needed and had very fast shipping!!
