Value Collection 262-4116 Expanding Lathe Arbor 1.25in Face

Product Description

The VALUE COLLECTION 262-4116 is an expanding lathe arbor designed to hold workpieces securely on a lathe during turning, boring, or finishing operations. The arbor features a 1.25-inch face diameter and a 4-inch overall length, providing a stable, centered grip on bored or through-hole workpieces. The expanding design allows the arbor to seat firmly inside the workpiece bore, transmitting rotational force without slippage. This type of tooling is standard in machine shops and production environments where machinists need repeatable, concentric workholding for medium-diameter parts.

Expanding lathe arbors are used in manual and CNC lathe setups where outside-diameter turning or facing must be performed on a part held from its internal bore. Typical applications include finishing turned rings, bushings, sleeves, and similar cylindrical components. The 4-inch overall length suits standard toolpost and tailstock setups on bench lathes and mid-size engine lathes. Machinists and toolroom technicians working in general metalworking, automotive, and light industrial maintenance environments are the primary users of this arbor style.

Key Features

• Expanding grip design centers and locks workpieces by their internal bore for concentric outside-diameter operations
• 1.25-inch face diameter accommodates medium-range bore sizes
• 4-inch overall length fits standard lathe setups without extended reach
• Shank diameter of 0.1285 inches sized for compatible lathe spindle or chuck mounting
• Compact 1.2-pound weight keeps rotational mass low during operation

Compatibility

Designed as an OEM-style workholding accessory for use on manual and CNC lathes accepting arbors with a 0.1285-inch shank diameter and a 1.25-inch face diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe workholding procedures. Power down and lock out the lathe spindle before mounting or removing the arbor. Confirm that the workpiece bore is clean and within the arbors expansion range before tightening to avoid damaging the bore or the arbor body. Follow shop safety practices and applicable OSHA machine-guarding requirements when operating rotating tooling.
