Value Collection 262-4128 Expanding Lathe Arbor

Product Description

The VALUE COLLECTION 262-4128 is an expanding lathe arbor designed to hold workpieces securely on a lathe for boring, turning, and finishing operations. The arbor features a 2.5-inch face diameter and a 4-inch overall length, making it suitable for machining applications that require a stable, centered workholding solution. The 1-inch shank diameter mounts directly into compatible lathe spindles or chucks. Expanding arbors grip from the inside of a bore, distributing clamping force evenly to minimize runout and protect workpiece geometry during cutting passes. Machinists and toolroom operators rely on this style of arbor for repetitive production runs and precision turning work.

This expanding lathe arbor is intended for use in manual and CNC lathe setups across job shops, toolrooms, and production machine shops. It is well suited for turning or facing operations on parts with a pre-bored center hole that needs to be referenced or further machined. The compact overall length of 4 inches keeps the setup rigid and reduces overhang deflection, which is important when working to close tolerances.

Key Features

• 2.5-inch face diameter provides a broad contact surface for secure workpiece engagement
• 4-inch overall length keeps overhang minimal for improved rigidity during cuts
• 1-inch shank diameter for direct mounting in standard lathe spindles or chucks
• Expanding design grips from the interior bore, centering the workpiece with even clamping force
• Single-piece package quantity allows individual purchase for targeted tooling needs

Compatibility

Designed as an OEM-style replacement or direct-fit expanding arbor for lathes accepting a 1-inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe toolholding setups. Before mounting, ensure the lathe spindle is fully stopped and the machine is powered down or locked out per facility lockout/tagout procedures. Insert the shank fully into the spindle or chuck and verify concentricity with a dial indicator before engaging the workpiece. Do not exceed the arbor's rated face diameter range when selecting workpieces, as improper fitment can cause workpiece ejection or damage to the arbor body.
