The Shock Wave Multiblade from Diasant Pulsar. What can't this blade do? It's a great blade for many uses! The Shock Wave can be used as a cup wheel for aggressive and smooth grinding. It’s thick enough that it can be used to cut 3/16” channels for rodding. The standard use of the Shock Wave is cutting stone; the blade runs up to 10,000 rpm. The Shock Wave can be ran wet or dry and attaches to a grinder with a 5/8”-11 connection.
