7/16"-48 HSS Round Adjustable Die

This 7/16"-48 high-speed steel round adjustable die cuts external threads on pipe, rod or tubing. Machinists, plumbers and maintenance technicians use it where a precise, wear-resistant thread form is required. The die suits manual die stocks and powered threading machines alike.

Compatibility check before ordering

Verify the workpiece diameter matches the 7/16" major thread size and that the thread pitch required is 48 threads per inch. Confirm your die stock or machine holder accepts a 1-1/2" outside-diameter round die. Ensure the material being threaded is compatible with high-speed steel cutting edges.

Sustained-load behaviour

High-speed steel construction provides improved wear life during extended threading runs compared with carbon-steel alternatives. Chamfered faces on both sides — 2 to 3 threads on one face, 1 to 1-1/2 on the other — ease starting and allow threading close to a shoulder without binding. The fine-pitch adjustment screw lets the operator open or close the die gradually, maintaining consistent thread quality over long production batches.
