The Carmex carbide thread mill is a full‑profile internal threading tool designed for precision in miniature parts. Ideal for machinists and manufacturers working with tight tolerances, it delivers clean, accurate internal threads at small sizes, including ISO M1 x 0.25 and 0‑80 UNF.

  • Tool type: Full‑profile carbide thread mill for internal thread milling, optimized for precise engagement inside holes.
  • Size / shank: No. 0 x 80 with MT11 shank for compatible, rigid mounting in standard holders.
  • Flutes: 3–4 flutes chosen to balance strength, cut quality, and chip evacuation in tight pockets.
  • Coating: Ultra‑fine triple blue PVD coating for wear resistance and reduced edge build‑up during threading.
  • Material: Solid carbide construction provides stiffness and long life in hard metals.
  • Threads supported: Internal threads, including ISO M1 x 0.25 and 0‑80 UNF threading capabilities.
  • Depth capability: Can cut thread depths up to 3.5 times the thread diameter depending on profile and hole geometry.

This tool is engineered to maximize stability and surface finish when threading from the inside of components. The carbide composition and advanced coating help maintain sharpness under challenging alloys, while the multi‑flute geometry promotes efficient material removal and smooth thread surfaces. Its compact No. 0 size is ideal for miniature assemblies found in precision instruments, small automotive components, and compact electronics housings, where reliable internal threads are critical for performance and assembly integrity. Use this tool to replace tapping in small bores, achieve consistent thread fits, and extend tool life in high‑demand production environments.
