Value Collection 262-3052 Expanding Lathe Mandrel

Product Description

The VALUE COLLECTION 262-3052 is an expanding lathe mandrel designed to hold workpieces from the inside diameter during turning operations. It accepts grip ranges from 9/16 inches to 21/32 inches, making it suitable for a range of bored or drilled workpieces that need to be held concentrically on a lathe. The arbor measures 6 inches in length, and the sleeve length is 2-3/4 inches. The shank diameter is 19/32 inches. Machinists and toolroom technicians use this type of mandrel when outside-diameter turning or finishing of a workpiece requires a secure, centered internal grip without marring the bore surface.

This expanding lathe mandrel is used in metalworking shops, production machining environments, and toolroom applications where accurate OD turning of bored workpieces is required. It is well suited for single-piece jobs and small-batch runs where quick setup and repeatable concentricity matter. The expanding design allows it to seat firmly within a range of internal diameters, reducing the need for multiple fixed mandrels when working with parts that fall within its grip range.

Key Features

• Grip range of 9/16 inches to 21/32 inches accommodates a variety of internal bore sizes
• Expanding design grips the workpiece bore internally for concentric OD turning
• 6-inch arbor length provides clearance and support for workpieces during turning
• 2-3/4-inch sleeve length engages the bore over a substantial contact area for stability
• 19/32-inch shank diameter for mounting in standard lathe tailstock or headstock setups

Compatibility

Designed as an OEM-style replacement and standard toolroom component for lathes accepting a 19/32-inch shank mandrel with a grip range of 9/16 inches to 21/32 inches.

Installation Notes

Installation is performed by qualified machinists familiar with lathe tooling setup. Before mounting the mandrel, ensure the lathe is fully powered down and all rotating components have stopped. Verify that the workpiece bore is clean and within the specified grip range before expanding the mandrel to avoid damage to the sleeve or bore surface. Follow standard shop safety practices and applicable OSHA machining guidelines when setting up and operating lathe tooling.
