  • Adjustable design allows precise thread sizing
  • Dual chamfers enable threading near shoulders
  • Fine-pitch screw gives smooth adjustment control
  • Complies with California Proposition 65 requirements

Thread size and application

This HSS round adjustable die cuts M39 x 4.5 threads with a 3-inch outside diameter. It is intended for machinists and maintenance technicians who need to produce or repair external threads on pipe, rod or fastener stock. The die suits manual or machine-held threading operations where adjustable fit is required.

Setup requirements

Verify that the workpiece diameter matches the M39 major diameter before cutting. Ensure the holder or die stock accommodates a 3-inch OD die and that the fine-pitch adjusting screw can be accessed or removed for holder-based adjustment. Confirm the material being threaded is compatible with high-speed steel tooling.

Upgrade path

Replaces fixed-size or carbon-steel dies when longer wear life and adjustable thread fit are needed. The jump is worthwhile for shops cutting repeated batches or threading close to shoulders where the dual chamfer (2 to 3 threads one side, 1 to 1-1/2 threads the other) reduces setup time.

Highlights

  • High-speed steel construction extends die life
  • Adjustable design allows precise thread sizing
  • Dual chamfers enable threading near shoulders
  • Fine-pitch screw gives smooth adjustment control
  • Complies with California Proposition 65 requirements
