7204 - 3" Ceramic Transitional 30/40#grit 4segment for EXTREMELY HARD CONCRETE. Use this when NOTHING else is cutting. Lower life but WILL cut that hard cap that is always slow to remove. These ceramics were proven to cut the hardest slabs! They are a 30/40#grit so also a great beginning when trying to polish a hard slab.
>4k sqft in life but will cut!
