  • 1 Inch Rapid Z-DRUM With Top Bearing – Fine

NSI Solutions LLC 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 with 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).


  • Fits 5/8-11 arbor threads (M14 version available)
  • Height matched to the Rapid Z™-CUT
  • Center water feed compatible
  • Maximum RPM 8500
  • Coarse grit (30/40 grit)
  • Rapid grinding of stone and quartz
  • Arbor and template follower rings machined from stainless steel
  • Corrosion-resistant hardware
  • Machined and assembled in the U.S.A.
