NSI Solutions Rapid Z-DRUM Replacement, 3-Inch, Coarse Grit

The NSI Solutions Rapid Z-DRUM is a 3-inch vacuum-brazed replacement drum wheel designed specifically for use with the Sink BULL.

The coarse-grit drum is used to remove material left by the Rapid Z-CUT and clean tight corner radiuses on square sink bowls. When equipped with bearings, the bearings ride along the template during operation.

The Rapid Z-DRUM is height matched to the Rapid Z-CUT, so the Sink BULL does not require a height adjustment when changing between the two tools.
