Value Collection 262-3064 Expanding Lathe Mandrel

Product Description

The VALUE COLLECTION 262-3064 is an expanding lathe mandrel designed to hold workpieces from the inside during turning, grinding, or finishing operations on a lathe. The mandrel expands to grip bores ranging from 1-1/2 inches to 2 inches, providing a secure, centered hold without requiring external clamping. The 1-1/2-inch shank diameter fits standard lathe spindle bores and tool holders, while the 5-inch sleeve length and 11-1/2-inch arbor length accommodate a range of workpiece depths. Machinists and toolroom technicians use this type of mandrel when concentricity between the bore and the outer diameter is critical.

This expanding lathe mandrel is suited for production and toolroom environments where inside-diameter workholding is required. Typical applications include turning the OD of bushings, sleeves, rings, and other cylindrical parts that must run true to a bored center. The 1-1/2- to 2-inch grip range covers a common bore size class found in medium-scale machined components. It is intended for use on manual engine lathes and compatible CNC turning centers that accept the corresponding shank diameter.

Key Features

• Expanding grip range of 1-1/2 inches to 2 inches suits a wide variety of bored workpieces
• 1-1/2-inch shank diameter for secure mounting in standard lathe spindle or tool holder
• 5-inch sleeve length provides stable workpiece support along the bore
• 11-1/2-inch overall arbor length accommodates deeper or longer workpieces
• Inside-diameter workholding maintains concentricity between bore and OD during turning

Compatibility

Designed as an OEM-style expanding mandrel for use on manual engine lathes and turning centers that accept a 1-1/2-inch shank, with a bore grip range of 1-1/2 inches to 2 inches.

Installation Notes

Installation and use of lathe mandrels should be performed by qualified machinists familiar with lathe workholding practices. Power down and lock out the lathe spindle before mounting or removing the mandrel. Ensure the shank is clean and fully seated in the spindle or holder before engaging the workpiece. Do not exceed the mandrel grip range, as over-expansion can damage the sleeve or the workpiece bore.
