About This Product
Dry Flush Cutting Blades for Angle Grinders
Alpha® Quad Turbo Rim Flush Cutting Diamond Blades convert compatible high-speed angle grinders into specialized flush-cutting tools. When installed with the appropriate Quad Drive Adapter, the blade mounts without a conventional lock nut, allowing the cutting edge to work closer to the material surface.
Turbo Rim Performance for Clean Dry Cuts
The turbo rim provides fast dry cutting with minimal chipping across demanding stone and fabrication applications. Available diameters from 4" through 10" allow the grinder blade size to be matched to the required cutting depth, access, and power tool.
Flush Cuts in Corners and Tight Areas
The flush-cut configuration supports clean 90-degree inside corners, cleanup cuts, sculpting, monument work, and other applications where a conventional saw blade cannot cut close enough to the surface. It is also useful for removing marks left by larger cutting blades and accessing confined work areas.
Quad Drive Mounting Configurations
The 4", 5", 6", and 7" flush cut blades use a 20mm Quad Drive connection and require the appropriate Quad Drive Adapter. The 8", 9", and 10" blades use a 20mm flange with eight holes, with the larger-diameter configuration designed to support cutting with the angle grinder's existing safety guard when properly equipped.
