1″ Rapid Z™-DRUM – Coarse
$139.95
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).
- 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)

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”.
