These are flexible polishing pads with a hybrid bond that works incredibly well on quartz and does a great job on granite as well. At the core of this system is the Phenom 3 Step System. Three steps gets it done on most quartz edge work. We found in our testing that adding a position 4 buff was useful in certain applications. Then we added an agrresive position zero if you need to do some shapping or agressive stock removal.
