5/16"-48 HSS Round Adjustable Die

The Drill America DWTSR112-51648 is a high-speed steel threading die with a 5/16"-48 thread specification and 1-1/2 inch outside diameter. It is designed for cutting external threads on rods, bolts or pipe sections in maintenance, repair and fabrication work.

Suited for thread cutting and repair tasks

Machinists and maintenance technicians who need to create or restore 5/16"-48 threads will find this die appropriate. It is not intended for users who require a different thread pitch, diameter or internal thread tapping capability.

Adjustable design with dual chamfers

The fine-pitch adjusting screw allows the die halves to expand or contract for precise fit control. Chamfers on both faces — 2 to 3 threads on one side and 1 to 1-1/2 threads on the other — support both standard threading and threading close to a shoulder. The bevelled slot permits holder-based adjustment when the screw is removed.
