Value Collection 428-7010 10 in 3-jaw Lathe Chuck Plain Back

Product Description

The VALUE COLLECTION 428-7010 is a 10-inch diameter, 3-jaw self-centering manual lathe chuck with a plain back mount, designed for use on manual lathes in machine shops and industrial production environments. 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.

This 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.

Compatibility

Designed 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.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The plain back mount requires that a properly fitted backplate be machined to match the lathe spindle nose before mounting the chuck. Power down and fully lock out the lathe before removing any existing chuck or mounting the new unit. Verify runout with a dial indicator after installation before returning the machine to service.
