UN Long Reach Thread Mill (TMLR)
Machines 2A/2B and 3A/3B Unified National threads
Long reach design supports threading in deep cavities and complex part features
Solid carbide construction provides rigidity, stability, and accuracy in extended applications
Available uncoated or with AlTiN+ or Versa (AlCrN) for application-specific performance
The UN Long Reach Thread Mill (TMLR) is engineered for precision threading in deep or hard-to-reach areas where standard tools can’t reach. Designed for extended-reach applications, it helps produce clean, consistent Unified National threads while maintaining rigidity and stability in challenging parts.
