Threading die for M35 x 2.5 threads

This Drill America round adjustable die cuts external threads sized M35 x 2.5 with a 2-1/2 inch outer diameter. It is made from high speed steel for extended wear life during threading operations. The die suits maintenance, repair and production work where accurate metric threads are required. Machinists and pipe fitters use it to create or restore threads on rods and pipes.

Chamfered faces and adjustable split

Both faces of the die are chamfered; one side offers a 2 to 3 thread lead for starting, the other a 1 to 1-1/2 thread lead for threading near a shoulder. A fine pitch screw adjusts the split die open or closed for precise fit. The bevelled slot allows the adjusting screw to be removed when the die is held in a machine holder, letting the holder’s screws control adjustment. High speed steel construction resists wear during repeated use.

Replaces worn fixed dies or smaller taps

This adjustable die replaces fixed dies that have lost size accuracy or cannot be tuned for fit. It also supersedes hand tapping when external threads are needed on long stock. The jump is worthwhile when thread diameter must be held within tight tolerance or when the same die must serve both through and shoulder threading. California Proposition 65 warnings apply to this product.

Questions about this item

What thread standard does the M35 x 2.5 die cut, and what diameter does it produce?

The die cuts an M35 metric thread with a 2.5 mm pitch, producing a 35 mm major diameter on the workpiece.

What holder size is required for the 2-1/2 inch outside diameter?

A die stock or machine holder that accepts a 2-1/2 inch round die body is needed to secure and drive this tool.

How do you adjust the thread fit using the fine-pitch screw, and what common step is missed?

Turn the fine-pitch screw to open or close the split die for the desired fit; the step often missed is removing the screw when the die is placed in a machine holder so the holder's own adjusting screws take over.
