MOQ 10pcs This 4 inch diamond cup wheel is used for grinding granite, marble, and other masonry materials. It comes in an aluminum body and a complete turbo type diamond segment. The turbo diamond segment is made separately through high temperature and pressure(hot pressing), and then it is sintered together with the aluminum body. Because the aluminum has a low melting point and it doesn't suit for high-frequency welding. Different from other sintered cup wheels, this manufacturing process remains the high concentration of the diamond segment, so it has a high performance and long lifespan. This tool can be used for dry grinding or wet grinding. The advantages and disadvantages are as follows: Wet or Dry Advantage disadvantage Wet Grinding The water can cool the diamond cup wheel when working;So the diamond cup wheel has a little longer lifespan; Will create slurry and it is hard to be deal with Dry Grinding Won't create slurry You need a vacuum cleaner SYF-K03-7SYF-K08SYF-K09
