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

Sink BULL™LT Complete Kit
**New** Sink BULL™LT
The Sink BULL™LT is the newest version of our heavy-duty, manual sink milling machine. It utilizes a simple, rigid, powerful design combined with your own inexpensive, shop-made, templates to make CNC quality sink cutouts. The Sink BULL™LT is the only sink milling machine or router-type machine with a long enough base to span a sink template. This means extra stability, no tipping, and a smaller template margin required. The Sink BULL™LT is constructed of heavy-duty anodized aluminum and stainless steel with corrosion-resistant hardware. It’s powered by a large 15 amp Makita grinder – GA7021 or GA7020 (USA), GA7031 (Canada), GA7040S01 (Australia). A strong single lever height adjustment and simple external water feed yield a quality U.S.A. made tool that is “STONE SHOP TOUGH”.
