Description
Our carbide burr with a 1/8″ (3mm) shank is often used on wood, glass, plastic, and stone sculpture. The various shapes of our rotary files perform an excellent job of carving and engraving. The hardness and durability of solid tungsten carbide burr guarantee the consistency of the project results. The sharpness of the carbide burr bits ensures that all the details are perfectly finished. Our 1/8″ (3mm) carbide burr works on most hobbyist rotary tool brands like Dremel, Wen, and Tacklife.
