Drill America HSS Round Adjustable Die

This Drill America high-speed steel round adjustable die cuts external threads on pipe or rod. The 1-3/8"-27 thread form suits plumbing and mechanical repair work where a precise, adjustable fit is required. The die is supplied new and ready for use in a compatible die stock or machine holder.

Suited for thread repair and custom threading

Plumbers and maintenance technicians who need to create or restore 1-3/8"-27 threads will find this die effective. It is not intended for internal thread cutting, for metric or other inch thread pitches, or for applications that require a fixed-size die without adjustment capability.

1-3/8"-27 thread specification

The die cuts a 1-3/8"-27 thread form, which is the single specification that determines whether this tool matches the required fastener or pipe size. Verify the thread pitch and diameter against the workpiece before purchase.

Questions about this item

What size die stock or holder do I need for the 2-1/2" OD?

Use a die stock or machine holder that accepts a 2-1/2 inch outside-diameter round die; the beveled slot lets you remove the adjusting screw for holder-based adjustment.

Will this die cut threads on a pipe that already has worn or damaged 1-3/8"-27 threads?

Yes — the 2-to-3-thread chamfer starts new threads cleanly while the 1-to-1-1/2-thread chamfer lets you chase threads close to a shoulder on existing pipe.

How can I verify the die is cutting the correct 27 threads-per-inch pitch after setup?

Measure the thread pitch on the freshly cut section with a thread gauge; it should read 27 TPI matching the die specification.
