Review on 🪒 3M Cubitron II Net Disc Roll 31656, Ultra-Fast Cutting, Super Durable, Maximum Dust Capture, 6 in, 320+ Grade, 50 Discs per Roll by Greg Bloom

The 3M Cubitron II is a well-made grinding wheel. It has 2 separate grinding surfaces which I have not seen on any other grinding wheel I have used. From my experience as a carpenter, I like that the disc doesn't clog so easily. I took a 320 grit wheel and sanded the old shellac off the chair. I would normally use 80 grit for rough sanding passes, but to see how tough 320 grit is I went for it. The old finish is easily removed with minimal effort that most other brands don't afford. After my test, the Cubitron still has quite a bit of life left. Even if it was an extreme test, I also tested it under normal conditions. With another part of the chair already sawed off, I tested the Cubitron on another grinding wheel I had at home. Comparing the two brands, Cubitron had a smoother finish to the touch. No clogging occurred in this test either. I definitely recommend it.
