Value Collection 315-1302 Round Die 3/4-20 2 Inch Od Hss

Product Description

The VALUE COLLECTION 315-1302 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. Built from high-speed steel (HSS), it holds a sharp cutting edge under friction and heat, making it well suited for repetitive threading tasks in shop or field environments. The die cuts a 3/4-20 UNEF right-hand thread profile and features an adjustable design that allows the operator to fine-tune thread fit. The 2-inch outside diameter fits standard round die stocks of that size. Machinists, pipefitters, maintenance technicians, and tool-and-die tradespeople are the primary users.

This die is used wherever a 3/4-20 UNEF external thread must be cut or chased on metal stock. UNEF (Unified National Extra Fine) thread form is common in precision mechanical assemblies, instrumentation fittings, and applications requiring fine thread engagement in thin-walled or hardened materials. The adjustable split design lets the user make a first pass at a slightly oversized diameter, then close the die to finish the thread to final tolerance. Typical settings include machine shops, maintenance facilities, and fabrication benches.

Key Features

• High-speed steel construction retains cutting edge at elevated operating temperatures
• Cuts 3/4-20 UNEF right-hand external threads to standard thread form
• Adjustable split design allows thread diameter fine-tuning for proper fit and tolerance
• 2-inch OD fits standard round die stocks sized for 2-inch dies
• Right-hand thread direction matches the most common fastener and fitting convention

Compatibility

Designed as an OEM-style replacement or standard round die for use in any 2-inch round die stock that accepts a 2-inch OD die.

Installation Notes

A licensed machinist or experienced tradesperson should seat the die squarely in the die stock before beginning a threading pass to avoid cross-threading or bell-mouthing. Apply cutting oil liberally to the workpiece and die during use to reduce heat buildup and extend tool life. Back off the die periodically to clear chips when threading longer lengths of stock. Inspect the die for chipped or worn cutting teeth before each use.
