Tungsten Carbide Sanding Tools

Tunco Manufacturing is the leader in the field of producing crushed tungsten carbide products, including custom sanding tools from sleeves to rubber drums. Our tungsten carbide coatings will extend the lifetime and sharpness of your tools, nearly reaching the lifetime of diamond tools. We also offer our patented Di-Carb, a diamond-like coating, and customized tools at a fraction of the cost of diamond-coated products. If you need a tool created and coated for a particular application, we have both in-house engineering and computer-aided design services available.

Sander Blades
Our sander and saw blades function for both cutting and sanding. They can also be used with either bench type or portable disc sanders, or circular saws. All of our tungsten-carbide grit products are designed for use on composites, fiberglass, reinforced plastics, rubber, and similarly abrading nonmetallic materials. Tunco tools will outlast traditional abrasives and high-speed steel-cutting tools.
