Value Collection 262-3062 Expanding Lathe Mandrel

Product Description

The VALUE COLLECTION 262-3062 is an expanding lathe mandrel designed to grip workpieces from 1.25 inches to 1.5 inches in diameter. The expanding sleeve mechanism applies uniform radial pressure to hold a part securely on the arbor during turning operations. With a 1.25-inch shank diameter, a 4-inch sleeve length, and a 9-inch overall arbor length, this mandrel fits a range of manual and CNC lathe setups. At 3.9 pounds, it provides solid mass for stable workholding. Machinists and toolroom operators use this type of mandrel when center-holding a bore is required for accurate outside-diameter turning or finishing.

This expanding lathe mandrel is suited for general metalworking and toolroom applications where a workpiece must be held by its bore rather than its outside diameter. It is appropriate for use on manual engine lathes and CNC turning centers capable of accepting a 1.25-inch shank. Typical applications include finishing turned components, truing outside diameters concentric to a drilled or bored hole, and repeat production runs requiring consistent workpiece location.

Key Features

• Expanding grip range of 1.25 inches to 1.5 inches accommodates a range of bore sizes
• 1.25-inch shank diameter for secure spindle or tailstock mounting
• 4-inch sleeve length distributes clamping force along the bore
• 9-inch arbor length provides clearance for a variety of workpiece depths
• 3.9-pound construction adds stability during turning operations

Compatibility

Designed as a standard expanding mandrel for use on manual engine lathes and CNC turning centers that accept a 1.25-inch diameter shank, where workpiece bore sizes fall between 1.25 inches and 1.5 inches.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The lathe spindle and any power feeds must be fully de-energized before mounting or removing the mandrel. Verify shank-to-spindle bore fit and taper cleanliness before seating. Do not exceed the stated grip range, as overextension of the expanding sleeve can damage the mandrel or the workpiece bore.
