This is a position zero pad....think of a 50ish grit pad. Sometimes you want something agressive in front of the three step. You can do light shaping with the step 1 pad...but you will smoke the it before the the other ones in the system.
This pad is the first pad in the 5 step system.
These are flexible polishing pads with a hybrid bond that works incredibly well on quartz and does a great job on granite as well.
