Full Profile - NPT

Solid carbide full profile thread mills for pipe threads
Emuge SHUR-THREAD  solid carbide thread mills are manufactured to the most exacting tolerances to provide maximum tool performance and part quality. The full profile thread design is the most stable form of thread milling and  can reduce cycle times when compared to single point tooling. Thread milling provides the highest level of threading process security, which is especially important in high value parts where tap breakage is a possible issue. SHUR-THREAD thread mills are available in a wide range of options, solid and coolant fed which allows for the maximum amount of flexibility when developing an efficient manufacturing process.

EMUGE offers 3 styles of NPT pipe thread mills:

  1. GFI-ECO - the economically priced solution
  2. GFI NPT - for production threading 
  3. GFI-API LP - high performance design for critical parts manufacturing


  • Designed for the production of internal and external threads
  • SHUR-THREAD thread mills are available for different thread sizes with standard thread profile (but for one pitch only)
  • A pre-drilled thread hole is necessary, including chamfer if needed
  • In order to avoid serious profile deviation in internal threads, the cutter diameter should not exceed 2/3 (with fine threads, 3/4) of the thread to be produced
  • With external threads, the cutter diameter should not exceed the diameter of the thread to be produced
