Built with a cast iron body, it delivers consistent centering performance with an axial runout of 0.0010 inches and a radial runout of 0.0016 inches. The chuck measures 8 inches in diameter and supports a maximum spindle speed of 2,500 RPM. Jaws are reversible, giving machinists flexibility to grip both small-diameter and large-diameter stock without a full jaw swap. It weighs 44.5 pounds and is sized for industrial lathe setups in machine shops, toolrooms, and production environments.\u003c\/p\u003e\n\u003cp\u003eThis chuck suits manual lathe operations in both job shop and production machining settings. The 8-inch diameter and jaw capacity range of 5\/32 inches minimum to 7-7\/8 inches maximum covers a wide variety of round, hex, and bar stock diameters. It is intended for machinists and machine tool operators working on metal-turning applications where repeatable centering and rigid workholding are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-centering 3-jaw design for fast, repeatable workholding setup\u003c\/li\u003e\n  \u003cli\u003eReversible jaws accommodate jaw capacity from 5\/32 inches to 7-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003eAxial runout of 0.0010 inches and radial runout of 0.0016 inches for precision turning\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 2,500 RPM\u003c\/li\u003e\n  \u003cli\u003eCast iron body construction for rigidity and vibration damping\u003c\/li\u003e\n  \u003cli\u003eThrough-hole diameter of 2.1654 inches supports bar-feed and through-spindle work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style manual lathe chuck for metal lathes accepting an 8-inch 3-jaw self-centering chuck configuration.
