SKU CH-PAM8-M1462

High-speed steel round adjustable die cuts external threads with chamfered faces and fine-pitch screw adjustment for precise fit

  • High-speed steel construction extends die life
  • Adjustable fine-pitch screw enables precise thread fit
  • Chamfered both sides for standard and shoulder threading
  • Beveled slot allows holder adjustment without removing screw
  • California Proposition 65 warning for cancer and reproductive harm

Threading Tool Application

This 2-1/2 inch HSS round adjustable die cuts external threads on pipe and rod. Machinists and plumbers use it to create or repair M31x1 threads in maintenance and fabrication work. High-speed steel construction resists wear during repeated threading operations. The die suits professional workshops and field repair kits.

Build Integration

The die fits standard 2-1/2 inch die stocks and machine holders for hand or powered threading. Its adjustable screw expands or contracts the cutting edges to achieve precise thread fit. Chamfered faces on both sides allow starting threads and threading close to shoulders without additional tooling. The beveled slot permits holder-mounted adjustment when the screw is removed.

Sustained Load Behaviour

High-speed steel retains cutting geometry under the heat generated by extended threading passes. The fine-pitch adjustment screw maintains consistent die tension throughout a production run. California Proposition 65 warnings indicate the product contains chemicals linked to cancer and reproductive harm. Proper lubrication and chip clearance preserve edge life during continuous operation.
