Carmex MT line internal thread mills deliver a precise, cost‑efficient solution for forming Unified threads (UNC, UNF, UNEF, UNS) from the inside of holes. Designed for professionals who need dependable internal threading in metal parts, these solid carbide tools combine durability with efficient threading performance on MT7 shank systems.

• Material: Solid carbide core for rigidity, wear resistance, and longer tool life.
• Flute count: 3–5 flutes designed to optimize chip evacuation and thread quality in a single pass.
• Thread forms: Internal threading for UN family standards (UNC, UNF, UNEF, UNS) to cover common engineering needs.
• Sizes and length: No. 8, No. 10, No. 12 thread options with a 32 mm length of cut for versatile applications.
• Shank/interface: MT7 Morse Taper shank for secure, versatile mounting on compatible milling machines.
• Design focus: Engineered to optimize the threading process, delivering consistent engagement and reliable results across materials.
• Cost efficiency: A durable, repeatable threading solution that helps reduce tooling costs and production downtime.

These thread mills are ideal for producing internal threads in housings, bushings, molds, and components where tapping isn’t practical or where through‑hole and blind‑hole threading must be performed in a single operation. The 3–5 flute configuration provides a balance of fast material removal and precise thread formation, while the solid carbide construction ensures wear resistance in demanding environments. With MT7 compatibility, you’ll find a dependable, scalable option for high‑throughput shops and precision tooling setups alike.
