VMC Vitro Cut Diamonds are of the latest technology. These resin bonded diamond abrasives can be used wet or dry and require fewer steps for a superior diamond polish. They are available in the following sequence: 00, 0, 1, 2, 3, 4. A #5 grit is available if necessary. The 00 cuts as agressive as a 50 grit metal bond diamond abrasive; however, it leaves a smooth scratch pattern since it is resin bonded. The 0 cuts as aggressive as a 100 grit metal bond diamond abrasive, also leaving the smooth resin scratch pattern. This eliminates the old problem of trying to remove the deep scratches left behind by expensive metal diamonds. If the floor does not need to be cut deep then you can start with a #2. Then all you have is three steps and you are finished! #1 cuts as aggressive as 30g resin but leaves a 50g finish #2 cuts as aggressive as 120g resin but leaves a 220g finish. #3 cuts as aggressive as 400g resin but leaves an 800g finish #4 polishes to an 1800g finish. #5 polishes to a 3500g finish. Vitro Cuts may be used on: marble, terrazzo, granite & concrete. The Vitro Cut Series available in 3" and 4" VELCROŽ BRAND FASTENERS-back, and also in 4" for the VMC DP4 Planetary Head. With fewer steps, a set of Vitro Cuts will cost you less than a set of the older style diamonds on the market, and think about the labor savings! Isn't technology great!
