1/2"-64 HSS Adjustable Threading Die

This Drill America round adjustable die cuts 1/2"-64 threads using high-speed steel for extended wear life. It is designed for threading pipes, rods or tubing in plumbing and general maintenance tasks. The adjustable mechanism lets the user fine-tune thread fit for different material conditions.

Chamfered Faces for Versatile Threading

Both faces are chamfered: one side offers a 2 to 3 thread lead for standard starts, while the opposite side provides a 1 to 1-1/2 thread lead for work close to shoulders. A fine-pitch adjustment screw expands or closes the die, and the beveled slot allows holder-mounted adjustment without the screw. This flexibility suits both hand and machine use.

Replaces Fixed-Size or Worn Threading Dies

This adjustable die replaces fixed round dies when thread fit must be corrected or when a single tool must cover slight diameter variations. The jump is worth it for shops that cut 1/2"-64 threads regularly and need repeatable fit without stocking multiple fixed sizes. It is not for users who require non-adjustable dies or different thread pitches.

Highlights

  • High Speed Steel construction extends die wear life
  • Adjustable design allows precise thread fit control
  • Chamfered both faces for easier thread starting
  • Fine-pitch screw adjustment enables accurate sizing
  • Beveled slot suits machine holder use
