Value Collection 314-1166 Round Die 14-20 Unc 1 in Hss

Product Description

The VALUE COLLECTION 314-1166 is a round threading die machined from high-speed steel for cutting external 14-20 UNC threads. It features a 1-inch outside diameter and a right-hand thread direction, making it compatible with standard die stocks and holders of that size. The adjustable design allows the user to dial in thread fit by tightening or loosening the set screw in the die stock, giving machinists and trades workers control over thread tolerance. At 0.5 pounds, it is a compact, purpose-built cutting tool suited for production threading and field repair work.

This die is used wherever a 14-20 Unified National Coarse external thread needs to be cut or re-chased. Typical applications include machine shops, maintenance facilities, and field service work involving threaded fastener repair or custom bolt fabrication. It is well suited for use by machinists, industrial mechanics, and maintenance technicians working with mild steel, aluminum, and other materials that fall within the cutting range of high-speed steel tooling.

Compatibility

Designed to fit standard round die stocks with a 1-inch bore. Suitable for cutting 14-20 UNC external threads on compatible workpiece materials within the cutting range of high-speed steel.

Installation Notes

Round dies are installed and used by machinists and maintenance technicians. Secure the die firmly in the appropriate 1-inch die stock before use and ensure the set screw is tightened to prevent rotation during the cut. Apply cutting fluid appropriate for the workpiece material to extend die life and improve thread quality. Inspect the die for wear or chipping before each use and replace if cutting edges are damaged.
