Value Collection 429-69101 10 Inch 6 Jaw Lathe Chuck

Product Description

The VALUE COLLECTION 429-69101 is a 10-inch diameter manual lathe chuck designed for self-centering workholding on metal lathes. It features six reversible, two-piece jaws that adapt to both standard and reversed gripping positions, making it suitable for a wide range of workpiece diameters and geometries. The cast iron body measures 3.492 inches in length and includes a plain back mount for direct adaptation to compatible lathe spindles. With a through-hole diameter of 2.835 inches, the chuck accommodates bar stock and shaft work efficiently. Machinists and tool room technicians rely on this style of chuck for general turning, facing, and boring operations where repeatable jaw positioning is required.

This chuck is intended for manual lathe applications in machine shops, maintenance facilities, and production environments. The adjustable, self-centering jaw design simplifies setup when changing between workpieces of varying diameters. The reversible two-piece jaws extend the effective gripping range without requiring separate jaw sets. Typical installations include engine lathes and toolroom lathes where a plain back chuck mount is the standard spindle interface. At 80 pounds, this is a heavy-duty unit that typically requires two-person handling or a hoist during mounting.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe spindle interfaces and chuck mounting procedures. Disconnect and lock out power to the lathe before removing or installing any chuck. At 80 pounds, use a hoist or two-person lift to prevent injury and protect the spindle bearings during mounting. Verify the backplate or spindle nose is clean, undamaged, and properly fitted before torquing the chuck to the spindle.
