3″ Rapid Z™-DRUM – Coarse
$289.95
A 3″ diameter vacuum brazed drum wheel, specifically designed for use with the Sink BULL™. Available in two grits with a top bearing to ride along the template. The coarse grit cleans up the rough surface left by the Rapid Z™-CUT and the fine grit further smooths the surface leaving it ready to polish. This is the only vacuum brazed drum wheel with reversible and replaceable drums. 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)
- Reversible, and replaceable diamond abrasive drum
- Height matched to the Rapid Z™-CUT
- Center water feed compatible
- Maximum RPM 8500
- Coarse grit = approximately 30/40 grit
- Fine Grit = approximately 120/150 grit
