Threading die for M28×1.5 pipe

This high-speed steel round adjustable die cuts M28×1.5 threads on pipe and tubing. The 2-inch outside diameter fits standard die stocks and machine holders. It is suited for maintenance, repair and fabrication work where precise pipe threads are required.

Wear life and adjustment

High-speed steel construction provides improved wear life during threading operations. Both faces are chamfered: one side has a 2 to 3 thread chamfer for starting, the other a 1 to 1-1/2 thread chamfer for threading close to a shoulder. A fine-pitch screw adjusts the die opening, or the screw can be removed for holder-based adjustment.

Safety notice

The product carries a California Proposition 65 warning for a chemical known to cause cancer and a chemical known to cause birth defects or other reproductive harm. No bundled accessories or software are included with this die.

Questions about this item

How do I install the M28x1.5 die in a 2" holder and which chamfer faces the workpiece?

Place the die with the 2 to 3 thread chamfer toward the workpiece for starting threads; the 1 to 1-1/2 thread chamfer goes toward the shoulder. Secure the die in the holder and use the holder's adjusting screws for fine alignment.

What maintenance or replacement will the HSS round adjustable die need after extended threading?

The high-speed steel cutting edges will dull with use; resharpen or replace the die when thread quality degrades or cutting force increases noticeably.

What limit appears first when cutting M28x1.5 threads continuously in tough material?

Heat buildup at the cutting edges reduces tool life fastest; use cutting fluid and moderate speed to delay wear on the HSS die.
