The Carmex 22IR12UN3MBMA is a right-hand laydown triangular insert made for internal thread turning on lathes and CNC machines. It covers UN thread standards including UNC, UNF, UNEF, and UNS, giving machinists and engineers a single reliable solution for creating internal threads in pipes, fittings, valves, and precision components across many industries.
- Wide thread compatibility: Handles multiple UN thread forms in one insert, reducing the need to change tools between different jobs and keeping production moving smoothly.
- Precision cutting geometry: Creates clean, accurate thread profiles with consistent pitch and depth, helping you achieve proper thread engagement and fewer rejected parts.
- Long-lasting insert construction: Maintains edge sharpness through extended runs in both everyday and high-demand materials, lowering overall tooling costs.
This insert supports reliable internal threading from routine maintenance work to more challenging production jobs. Its consistent performance helps minimize downtime, reduce rework, and deliver threads that meet specifications on the first pass.
