The Hardinge R8 round smooth stepped collet is a useful tool for holding metals, plastics, carbide, graphite, and ceramics in industrial manufacturing applications. These cone-shaped sleeves have one or more slots along their length to allow expansion and contraction and have a center hole that is cylindrical, square, or hexagonal. They are typically made of spring steel and feature a tapered collar that tightens the collet to provide a fast and strong clamping action that ensures accurate centering of the workpiece resulting in low runout. This makes it ideal for high-volume production of precision parts. Hardinge Inc. is a well-known manufacturer of turning, milling, grinding, and workholding products.
