SKU CH-HH4C-ZAR7T

A high-speed steel round adjustable die cuts M4 x 0.8 threads with a 1" outside diameter for improved wear life

  • High-speed steel construction for extended wear life
  • Adjustable fine-pitch screw allows precise thread sizing
  • Dual chamfer design handles through-holes and shoulder threading
  • 1-inch outside diameter fits standard die stocks
  • California Proposition 65 warning applies to this product

Threading Application

The Drill America M4 x 0.8 High Speed Steel Round Adjustable Die cuts external threads on rods or pipes. It suits maintenance technicians and metalworkers who need to create or repair metric threads in a workshop or field setting.

Die Selection

This die replaces a worn or fixed-size cutting tool when adjustable thread fit is required. The fine-pitch adjustment screw lets the user open or close the die for precise class-of-fit control, making the switch worthwhile when standard solid dies cannot achieve the needed tolerance.

Sustained Cutting Behavior

High Speed Steel construction provides improved wear life during repeated threading operations. Chamfered faces on both sides — 2 to 3 threads on one face and 1 to 1-1/2 on the other — support consistent chip flow and allow threading close to shoulders without binding during extended use.

Questions about this item

What is the outside diameter of this M4 x 0.8 adjustable die?

The die has a 1 inch outside diameter and fits standard die stocks or machine holders made for that size.

How do you adjust the thread size on this round die?

A fine-pitch adjusting screw forces the die halves apart or lets them spring together; the screw can be removed so the holder's own screws make the adjustment.

What maintenance does this high-speed steel die need over time?

Keep the cutting edges clean and lightly oiled; re-sharpen or replace the die when threads become rough or undersized from wear.
