Carmex Carbide Thread Mills are single‑point, full‑profile tools designed for precise internal threading. Built for reliability, these trapezoidal (TR) thread mills deliver consistent, high‑quality threads in metal parts and housings.

• Profile: Trapezoidal (TR) full‑profile, single‑point internal thread mills for robust thread engagement.
• Sizes: TR12 and TR14 with MT11 shank for compatibility with standard holders.
• Thread range: Capable of cutting internal threads from ISO M1 x 0.25 up to 0-80 UNF.
• Flutes: Multi‑flute design (3–4 flutes) for improved rigidity and efficient chip evacuation.
• Depth capability: Thread depth up to 3.5 × the thread diameter (profile dependent).
• Material: Carbide construction for exceptional wear resistance and long tool life.
• Coating/Grade: Triple blue PVD coating with an ultra‑fine sub‑micron grade for smoother cutting and reduced wear.
• Shank: MT11 shank compatibility for secure, precise tool engagement in CNC milling setups.

These thread mills enable precise internal threading with reliable surface finishes, reducing secondary operations and cycle times. The carbide composition and specialized coating are chosen to withstand demanding materials and higher cutting speeds, while the TR profile provides strong thread engagement in trapezoidal threads. Ideal for manufacturing small to mid‑sized internal threads in fasteners, housings, and mechanical components, they offer predictable performance and long service life when used in proper CNC conditions.
