Value Collection 315-1165 Round Die 1/2-27 1 Inch Od Hss

Product Description

The VALUE COLLECTION 315-1165 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. It is ground from high-speed steel for wear resistance across a range of materials including mild steel, aluminum, and brass. This die cuts a 1/2-27 right-hand thread to the UNS thread standard and measures 1 inch in outside diameter, fitting standard 1-inch die stocks and holders. The adjustable design allows the operator to fine-tune thread fit by opening or closing the die slightly, useful for achieving a proper class of fit without scrapping the workpiece. Machinists, tool-and-die technicians, and maintenance mechanics are the typical users.

This die is suited for production and maintenance applications where a 1/2-27 UNS thread is required. Common use cases include threading barrel components, hydraulic fittings, and specialty fasteners that call for the 27-threads-per-inch pitch on a half-inch nominal diameter. It is compatible with any standard 1-inch OD die stock or ratchet handle that accepts a round die of this diameter. The right-hand thread direction is the conventional orientation for most threaded assemblies.

Key Features

• 1/2-27 UNS thread form, right-hand direction
• 1 inch outside diameter fits standard 1-inch die stocks
• High-speed steel construction for extended tool life
• Adjustable design allows fine-tuning of thread fit and class
• Single-piece round die profile for consistent thread geometry

Compatibility

Designed for use in any standard 1-inch round die stock or ratchet die holder that accepts a 1-inch OD round die. Suitable for cutting 1/2-27 UNS right-hand external threads on compatible workpiece materials.

Installation Notes

Secure the die in a properly sized die stock before use and confirm the set screw or adjustment screw is tightened to hold the die without cracking it. Apply cutting oil or threading fluid to the workpiece before and during threading to reduce heat and extend die life. Back off the die periodically to break chips and prevent galling, particularly on steel stock. Inspect the die for chipping or wear before each use and replace if cutting edges show visible damage.
