Carmex MT line solid carbide thread mills are engineered for precise internal threading, delivering reliable UNC/UNF/UNEF/UNS threads in a single setup. Designed for machinists who value efficiency and consistency, this 1/2 x 13 internal thread mill with MT7 shank is ready to elevate your threading workflow.

• Solid carbide construction: Built for rigidity and wear resistance to maintain thread accuracy through tough materials and high-speed machining.
• Internal thread milling: Specifically designed to cut internal threads in cavities and pre-assembled holes with clean, defined profiles.
• Universal thread compatibility: Supports UN/UNC, UNF, UNEF, and UNS thread standards for versatile applications.
• Thread size: Precisely features 1/2 x 13 internal thread capability for common connector and fastener applications.
• MT7 shank: Compatible with standard MT7 toolholders for secure, repeatable tool seating and easy integration into existing rigs.
• 3–5 flute design: Optimizes cutting action and chip evacuation, balancing speed, accuracy, and surface finish in a range of materials.
• Efficient and cost-conscious: Aimed at delivering reliable threading performance with economical tooling costs per part.

This internal thread mill is ideal for machine shops and job shops tackling medium to high-volume threaded holes in metal parts. Its combination of carbide hardness, multi-flute geometry, and MT7 compatibility helps you achieve consistent thread quality, reduce cycle times, and simplify tooling inventory without sacrificing precision.
