Osg 2707500 Round Threading Die 9/16-18 Unf Hss

Product Description

The OSG 2707500 is a round threading die designed to cut external threads on iron and steel workpieces. Built from high-speed steel (HSS), this die delivers the hardness and heat resistance needed for production and maintenance threading operations. It cuts a 9/16-18 UNF right-hand thread profile and features an adjustable design that allows minor diameter compensation to achieve a precise thread fit. With a 1.5 inch outside diameter and 0.5 inch thickness, it fits standard die stocks and die handles sized for 1.5 inch round dies. Machinists, toolmakers, and maintenance mechanics use this die for fabrication, repair, and replacement of threaded fasteners and fittings.

This die is suited for threading operations on iron and steel in job shop, manufacturing, and MRO maintenance environments. The 9/16-18 UNF designation makes it appropriate for applications requiring a fine unified thread, common in automotive, hydraulic, and precision mechanical assemblies where a finer thread pitch improves clamping force and vibration resistance. The adjustable feature is particularly useful when cutting threads to a specific class of fit or when compensating for tool wear over time.

Key Features

• High-speed steel construction for hardness and heat resistance during threading operations
• Adjustable design allows diameter compensation for precise thread class control
• Cuts 9/16-18 UNF right-hand external threads
• 1.5 inch outside diameter fits standard round die stocks
• Rated for use on iron and steel workpieces
• OSG Series 134 construction for consistent thread geometry

Compatibility

Designed for use on iron and steel workpieces requiring a 9/16-18 UNF right-hand external thread. Fits die stocks and die handles accepting a 1.5 inch round die.

Installation Notes

Install this die securely in a properly sized 1.5 inch round die stock before use. Apply cutting oil or threading fluid generously to the workpiece and die to reduce friction and extend tool life. Ensure the workpiece is securely fixtured or held in a vise before applying torque. Periodically back off the die during threading to clear chips and prevent galling, especially in deeper threading operations.
