Import 20490 Round Die M12 X 1.25 1 Inch Od Hss

Product Description

The IMPORT 20490 is a round threading die designed to cut external metric threads on rod, bolts, and fastener stock. It produces M12 x 1.25 threads — a fine-pitch metric profile — and is manufactured from high speed steel (HSS) for durability across repeated use on ferrous and non-ferrous materials. The die measures 1 inch in outside diameter, fits standard 1-inch die stocks and holders, and features an adjustable design that allows slight thread diameter variation for fit tuning. Right-hand thread direction conforms to standard metric fastener convention. Machinists, tool and die workers, and maintenance technicians use this die for thread repair and new thread cutting in shop and field environments.

This die is suited for threading M12 x 1.25 fine-pitch metric applications in general machining, maintenance repair, and manufacturing settings. The 1-inch OD fits widely available round die holders and stocks used in both manual hand threading and bench-mounted operations. Typical applications include threading steel rod, stainless, aluminum, and brass stock where an M12 fine-pitch thread form is required. It is a single-piece unit sold individually.

Key Features

• M12 x 1.25 fine-pitch metric thread profile for precision threading applications
• High speed steel construction resists heat and wear during cutting
• Adjustable design allows minor diameter tuning for fit and thread class
• Right-hand thread direction — standard orientation for metric fasteners
• 1 inch outside diameter fits standard round die stocks and holders

Compatibility

Designed as a replacement or supplemental round die for use in standard 1-inch OD round die holders and die stocks configured for metric threading operations.

Installation Notes

Round threading dies are installed and used by machinists and maintenance technicians using a matching round die stock or holder. Secure the die firmly in the holder using the set screws before applying cutting pressure. Apply appropriate cutting fluid to the workpiece before threading 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.
