The chuck body is constructed from cast iron and ships complete with a chuck wrench and a set of two-piece hard reversible jaws. With an axial runout of 0.0030 inches and an 80 mm (approximately 3.15 inches) through-hole diameter, this chuck suits a wide range of turning operations where repeatable centering and rigid workholding are required. It is installed and serviced by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for manual lathe applications in both job shop and production settings. The self-centering 3-jaw configuration allows for fast workpiece loading and consistent centering without individual jaw adjustment, making it well suited for cylindrical stock and hex material. The plain back mount requires the user to machine or source a backplate matched to the specific lathe spindle. The reversible two-piece jaw design extends the chuck's usable range across both small-bore and larger-diameter workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-inch (254 mm) chuck diameter for large-capacity turning work\u003c\/li\u003e\n\u003cli\u003e3-jaw self-centering design for fast, repeatable workpiece loading\u003c\/li\u003e\n\u003cli\u003eCast iron body provides rigidity and vibration damping during cuts\u003c\/li\u003e\n\u003cli\u003eTwo-piece hard reversible jaws expand gripping range for varied stock sizes\u003c\/li\u003e\n\u003cli\u003eAxial runout of 0.0030 inches for consistent concentricity\u003c\/li\u003e\n\u003cli\u003e80 mm through-hole diameter accommodates bar stock pass-through\u003c\/li\u003e\n\u003cli\u003eIncludes chuck wrench and reversible jaw set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a plain back mount lathe chuck requiring a user-machined or separately sourced backplate matched to the specific lathe spindle nose; no specific lathe model compatibility was provided in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician.
