Value Collection 262-4024 Expanding Lathe Arbor 0.375in Face 3in Oal

Product Description

The VALUE COLLECTION 262-4024 is an expanding lathe arbor designed to hold workpieces securely on a lathe spindle during turning, boring, and finishing operations. The arbor features a 0.375 inch face diameter and a 3 inch overall length, making it suited for light-duty workholding applications where a positive, centered grip is required. The expanding design allows the arbor to grip from the inside of a bore, providing accurate, repeatable workholding without the need for external clamping fixtures. Machinists and toolroom technicians install this type of arbor when working with parts that require internal mounting to maintain concentricity throughout the operation.

This expanding lathe arbor is used in manual and CNC lathe setups for machining small-diameter parts that require internal bore mounting. Typical applications include finishing turned components, holding thin-walled rings, bushings, or sleeves, and any operation where an external chuck jaw would interfere with the workpiece geometry. The compact 3 inch overall length keeps the setup close to the spindle nose, reducing overhang and minimizing vibration during cuts.

Key Features

• 0.375 inch face diameter for small-bore internal workholding
• 3 inch overall length minimizes spindle overhang and vibration
• Expanding design centers and grips from inside the bore for accurate, repeatable setups
• Compact form suits tight-clearance turning and finishing operations
• Single-piece packaging for individual toolroom or shop use

Compatibility

Designed as a standard expanding lathe arbor for use with manual and CNC lathes accepting workpieces with a bore sized to accept a 0.375 inch face diameter arbor.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before mounting the arbor, ensure the lathe spindle is fully stopped and the machine is locked out per shop lockout/tagout procedures. Verify the workpiece bore is clean and free of burrs before seating the arbor to ensure proper expansion and concentricity. Do not exceed the arbor's rated holding capacity, and inspect the expanding mechanism for wear or damage before each use.
