Guys! The PCD is what’s up!
If you haven’t tried it, maybe you should, PCD stands for Polycrystalline Diamond and is a cup wheel that lasts longer and is much more aggressive than most traditional diamond cup wheels out there. It efficiently removes surface coatings, glue, urethanes, mastic, and paint during high-performance surface grinding on concrete, tile, and asphalt surfaces.
The attached photo is what it looks like.
Happy Grinding!
