Threading die for 11/16"-40 pipe

This HSS round adjustable die cuts 11/16"-40 threads on pipe and tubing. It is made from high-speed steel for improved wear life during manual or machine threading operations. The die suits plumbers, maintenance technicians and fabricators who need to create or repair external threads to this specific size.

Chamfered faces for smooth starts

Both faces of the die are chamfered to reduce cutting force and heat during initial engagement. One side has a 2 to 3 thread chamfer for general threading, while the other has a 1 to 1-1/2 thread chamfer for work close to a shoulder. The fine-pitch adjustment screw allows the die to be opened or closed for precise thread fit without excessive power draw.

Adjustable for sustained production

The slotted, beveled design lets the die be locked in a machine holder where the holder's own screws control adjustment. This arrangement maintains consistent thread dimensions over long runs without the die shifting under load. High-speed steel construction resists dulling during repeated cuts, keeping thread quality steady across multiple pieces.

Questions about this item

How do I install the 11/16"-40 HSS round adjustable die in a die stock, and what step is often missed?

Insert the die with the 2 to 3 thread chamfer facing outward for starting threads; the beveled slot must align with the holder's adjusting screws so the fine-pitch screw can be removed for machine use.

What maintenance or replacement will the 11/16"-40 HSS round adjustable die need over time?

Cutting edges dull with use; apply cutting oil each session and store dry to maximise high-speed steel wear life, replacing the die when threads become undersized or torn.

What limit appears first when using the 11/16"-40 HSS round adjustable die continuously on tough material?

Heat buildup in the high-speed steel cutting faces reduces hardness and accelerates wear, so frequent cooling pauses and lubrication are essential to maintain thread quality.
