The Carmex Thread Mills Carbide Mini Type MJ 8 x 1.25 MT7 is a high‑precision thread milling tool designed for fast, reliable internal and external threading across a wide range of materials, including hardened alloys. Built for deep‑hole work, it delivers steady performance at elevated speeds with a compact, efficient profile.

• Tool Grade & Coating: MT7 sub‑micron carbide with Titanium Aluminum Nitride (TiAlN) multi‑layer coating (ISO K10‑K20) for superior wear resistance and high‑speed cutting.
• Through‑Coolant Ready: Coolant through the flutes provides excellent heat management and chip evacuation, especially beneficial in deep holes.
• Flute Design: Spiral flutes offer smooth cutting action; 3–5 flutes shorten machining time while maintaining rigidity and control.
• Threading Versatility: The same tool can produce a wide range of thread sizes and pitches, and perform both external and internal threading with accuracy.
• Depth Capability: Engineered to enable threading in deep holes, reducing setup changes and improving cycle efficiency.
• Material Range: General‑purpose performance across materials, including hardened workpieces up to 45 HRc.
• Durability & Life: Triple coating and advanced geometry contribute to longer tool life and consistent performance in demanding jobs.
• Size & Compatibility: MJ 8 x 1.25 with MT7 shank, designed for compatibility with MT7 holders and standard milling setups.

Ideal for shops that require versatile, high‑speed threading with minimal downtime. Use this tool for precision thread milling in automotive components, aerospace fasteners, hydraulic fittings, and other assemblies where deep‑hole threading, both internal and external, is common. The combination of high cutting speeds, effective cooling, and a rugged carbide design translates to shorter cycle times, reliable results, and fewer tool injuries during heavy‑duty threading tasks.
