1/4"-27 HSS Round Adjustable Die

This High Speed Steel round adjustable die cuts 1/4"-27 threads on pipe or rod. It is designed for plumbing and mechanical threading tasks where improved wear life is required. The die suits professional mechanics and maintenance technicians who need reliable thread cutting.

Replaces worn or fixed-size dies

A fixed die cannot compensate for wear, so thread accuracy drops over time. This adjustable die uses a fine-pitch screw to open or close the cutting edges, restoring size without replacing the tool. The jump is worth it when repeatable thread fit matters across multiple jobs.

Sustained threading performance

High Speed Steel construction resists heat buildup during extended cutting sessions. Chamfered faces on both sides — 2 to 3 threads on one side and 1 to 1-1/2 threads on the other — allow smooth starts and threading close to shoulders. The beveled slot permits holder-based adjustment for machine use.

Questions about this item

What size die stock or holder does the 1-1/2" OD round die require?

The die has a 1-1/2 inch outside diameter, so it fits a die stock or machine holder made for that size. The holder's internal adjusting screws take over once the die's own screw is removed.

Which side of the chamfered die faces the workpiece when starting a new thread?

Use the side with the 2 to 3 thread chamfer for normal threading; the 1 to 1-1/2 thread chamfer side is for threading close to a shoulder.

How often should cutting fluid be applied to this high-speed steel die during use?

Apply cutting fluid continuously while threading to reduce heat and extend the high-speed steel die's wear life.
