3″ Rapid Z™-CUT with Top Bearing
$389.95
The Rapid Z™-CUT is a 3″ diameter, stacked blade type Z Wheel, specifically designed for use with the Sink BULL™ to shape sink cutouts. It comes with a bearing and ring system designed to ride along a template and help compensate for blade wear. It excels at grinding away stone /quartz quickly but will always leave a small amount to be cleaned up with a drum wheel as the final step. The blades can be rearranged to minimize “apple coring” and they can be replaced easily. It’s center water feed compatible (note: the Sink BULL™ does not use center water feed).
- Fits 5/8-11 arbor threads (M14 version available)
- Center water feed
- Maximum RPM 12,000
- Uses 12 replacement blades
