NSI Rapid Z-DRUMS Center Water Feed with Top Bearing Guide

For the 1 inch DRUM -
A 1″ diameter vacuum brazed drum wheel, specifically designed for use with the Sink BULL™. This is the bit you need to clean out the tight corner radius on square sinks.  Available in two grits with a top bearing to ride along the template. The coarse grit cleans up the extra material left by the Rapid Z™-CUT and the fine grit further smooths the surface leaving it ready to polish. The height matches the Rapid Z™-CUT so height adjustments on the Sink BULL are not required between bits. It is center water feed compatible (note: the Sink BULL™ does not use center water feed).
