GRINDING Solutions

High-Quality Tungsten Carbide Shaping & Grinding Tools

Tunco Manufacturing specializes in high-quality grinding tools designed to shape difficult materials, like fiberglass, rubber, plastic, and more. Manufacturing with abrasive crushed Tungsten Carbide coatings or our patented Di-Carb coating, the lifetime of our tools will approach the life of diamond-coated shaping tools at a fraction of the cost.
