Value Collection 262-4127 Expanding Lathe Arbor 2in Face 4in Oal

Product Description

The VALUE COLLECTION 262-4127 is an expanding lathe arbor designed to hold workpieces securely on a lathe during turning, boring, and finishing operations. With a 2-inch face diameter and a 1-inch shank diameter, this arbor mounts to the lathe spindle and expands radially to grip the bore of a workpiece from the inside. The 4-inch overall length provides clearance for a range of part geometries. It weighs 3.1 pounds and is suited for shop machinists and toolroom professionals who need reliable, repeatable workholding without external clamping fixtures.

This expanding lathe arbor is used in machine shop environments for both production and toolroom applications. It is well suited for turning operations where a workpiece must be held by its internal bore rather than its outer diameter. Typical installations include finishing turned rings, bushings, sleeves, and similar cylindrical parts. The expanding design centers the workpiece concentrically on the arbor axis, which is critical for maintaining runout tolerances during finish passes.

Key Features

• 2-inch face diameter provides a broad contact surface for stable workpiece engagement
• Expanding design grips workpiece bores from the inside for concentric, repeatable holding
• 4-inch overall length accommodates a variety of part geometries and clearance requirements
• 1-inch shank diameter for direct mounting to compatible lathe spindle tooling
• 3.1-pound construction reflects solid material mass suited for rigid turning operations

Compatibility

Designed as a general-purpose expanding lathe arbor compatible with lathes accepting a 1-inch shank diameter tooling interface. Verify spindle bore and collet or chuck capacity before installation.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with lathe workholding procedures. Power down and lock out the lathe before mounting or removing the arbor. Confirm that the shank seats fully and is secured in the spindle before engaging the drive. Inspect the expanding mechanism for wear or debris before each use to ensure consistent grip and runout performance.
