Saburr Tooth grinding wheels use the same carbide coating technology as the smaller Saburr Tooth tools. They are very long wearing, easy to control and will not load on most materials. They are ideal for use as an intermediate step between a fast wood removal tool, such as the Arbortech tools, and the beginning of the sanding process. The New Whisper Carving Wheel allows you to clear material quickly and not leave deep scratches. This rounded profile allows you to use the top of the wheel for working on flat and convex surfaces and then the rounded sides allow you to sweep down into concave areas (like bowls) without digging in to the side of your project. The 4” diameter wheels requires a 4" or 4 1/2" angle grinder with a metal guard.
