Value Collection 262-2120 Standard Lathe Mandrel

Product Description

The VALUE COLLECTION 262-2120 is a standard lathe mandrel used to hold workpieces between centers during turning, grinding, or finishing operations. The mandrel features a 1-5/16 inch face diameter and an overall length of 8-1/4 inches, making it suited for mid-range workpiece bores that require accurate concentricity during machining. Machinists and tool room technicians use this type of mandrel when a part must be rotated on a fixed axis to achieve consistent outside-diameter accuracy relative to an existing bore. It installs between lathe centers and is driven by a lathe dog secured to the flanged end.

This mandrel is appropriate for use on manual engine lathes and toolroom lathes in job shop, production, or maintenance machining environments. It is designed for workpieces that have a pre-machined bore matching the 1-5/16 inch face diameter. Typical applications include finishing turned parts, grinding ODs to a bore, and general concentric turning work where the bore serves as the datum surface. The part ships individually and is sold as a single unit.

Key Features

• 1-5/16 inch face diameter for accurate workpiece mounting through a matching bore
• 8-1/4 inch overall length provides sufficient span for stable center-to-center support
• Standard mandrel design compatible with lathe-dog drive for positive rotation
• Single-piece unit — no assembly required before use
• Weighs 3.31 pounds for solid, vibration-resistant performance during cuts

Compatibility

Designed as an OEM-style replacement and standard toolroom mandrel suitable for use on manual engine lathes and toolroom lathes that accept between-center workholding with a 1-5/16 inch bore workpiece.

Installation Notes

Installation is performed by qualified machinists familiar with between-center lathe work. Before mounting, ensure the lathe is powered off and the spindle is locked. Press or tap the mandrel into the workpiece bore with appropriate force — never use impact methods that could damage the taper or bore finish. Secure the lathe dog to the drive flange and confirm center engagement before initiating any cutting pass.
