Carmex Thread Mills Solid Carbide - Internal Thread - UN (UNC UNF UNEF UNS) - No.5 x 40 - MT7

The Carmex MT line delivers a precise, cost-conscious solution for internal thread milling. Designed for professionals who need reliable UN-threading capabilities in a single, streamlined operation, this solid carbide tool excels where accuracy and efficiency matter most.

• Tool Material: Solid carbide construction for rigidity, wear resistance, and long tool life in a variety of materials.
• Threading Standards: Internal thread milling for Unified Thread Standards (UNC, UNF, UNEF, UNS) to cover a wide range of applications with one tool.
• Flute Configuration: 3–5 flutes that enhance cutting efficiency, improve chip evacuation, and support stable thread formation.
• Size and Interface: No.5 x 40 with MT7 shank, enabling compatibility with common milling centers and MT7 tool holders.
• Cutting Geometry: Optimized geometry for clean thread profiles, reduced burrs, and consistent hole-to-hole tolerances.
• Applications: Ideal for threading through-holes and blind-holes in aluminum, steel, and other machinable materials where cost per thread matters.

With the MT line, you can replace multiple tapping operations and achieve reliable internal threads in fewer passes. The solid carbide body provides stiffness for precise thread formation, while the multi-flute design supports efficient material removal and smooth finishes. This makes it a practical choice for shops aiming to lower cycle times and tooling costs without compromising thread quality. For best results, pair with appropriate feeds and speeds for your material, and use coolant to maintain tool life and thread integrity.
