Value Collection 315-1550 Round Die 1-5/16-12 Uns Hss

Product Description

The VALUE COLLECTION 315-1550 is a round threading die designed to cut external threads on bolts, studs, and round stock. It cuts a 1-5/16-12 thread profile to the UNS (Unified National Special) standard with a right-hand thread direction. Manufactured from high-speed steel (HSS), the die retains cutting hardness through heat generated during threading operations. An adjustable design allows the operator to fine-tune thread fit by slightly expanding or compressing the die body. Machinists, tool-and-die workers, and maintenance mechanics use this die with a standard round die stock to chase worn threads or cut new ones from bar stock.

This die is suited for production and maintenance applications where a 1-5/16-12 UNS thread is required. Common scenarios include repair of hydraulic cylinder rods, custom fastener fabrication, and restoration of damaged external threads on industrial equipment. The right-hand thread direction covers the vast majority of standard fastener applications. It is sized for use in a round die holder that accepts the corresponding die outside diameter.

Key Features

• 1-5/16-12 UNS thread profile for a coarser-than-standard pitch in this diameter range
• High-speed steel construction maintains cutting edge hardness under heat and friction
• Adjustable die body allows thread fit to be dialed in for proper tolerance
• Right-hand thread direction suits standard fastener and component applications
• Single-piece die ships individually, ready for use in a compatible round die stock

Compatibility

Designed for use in a standard round die holder sized to accept this die's outside diameter. Verify the die holder bore matches the die OD before use.

Installation Notes

This die is installed and operated by a machinist or maintenance technician using a round die stock (die wrench) of the correct size. Secure the die in the stock using the set screws before threading begins, and apply cutting oil generously to the workpiece to reduce heat and extend die life. Back the die off periodically to clear chips and prevent thread damage. Never attempt to force the die through material harder than what the HSS cutting edges are rated to handle.
