The DW4772s diamond matrix design gives this grinding wheel up to 350 times longer life than other conventional abrasives. This four-inch diamond cup grinding wheel features a maximum speed of 15,000 RPM and has a 5/8-inch arbor.
DEWALT Diamond Cup Wheels are designed to be used on small and large angle grinders. They are designed with an optimized cutting matrix. The high diamond concentration provides for a faster cut rate while the high quality of the diamonds provide longer blade life. The consistent diamond distribution and concentration provide high performance. A double row of diamonds on these blades provides for heavy material removal and provides longer life.
