The Carmex Thread Mills Carbide Mini Type is a compact, MT7-coated thread milling tool engineered for metric threading. It’s ideal for machinists who need fast, accurate internal and external threads (notably M4 x 0.7) in deep holes and across hardened materials.

• Grade and coating: MT7 sub‑micron carbide with a Titanium Aluminium Nitride multi‑layer coating (ISO K10–K20) for exceptional wear resistance and heat tolerance.
• Speed and efficiency: Optimized for medium to high cutting speeds, delivering shorter cycle times without compromising thread quality.
• Threading versatility: Produces a wide range of metric threads, both external and internal, including M4 x 0.7 and adjacent pitches.
• Deep‑hole capability: Through‑coolant design and short profile support reliable threading in long, deep cavities and narrow bores.
• Flute geometry: Spiral flutes provide smooth cutting action with efficient chip evacuation; multi‑flute configuration (3–5 flutes) reduces machining time.
• Profile and durability: Short tool profile lowers cutting forces and minimizes the risk of breakage, enhanced by a durable triple coating for extended life.
• Material compatibility: Capable of machining hardened materials up to 45 HRc, widening its use across demanding applications.

This mini thread mill is a versatile solution for producing precise metric threads in challenging setups—deep holes, hardened workpieces, and tight tolerances—without the need for tapping. Its combination of high-speed performance, deep‑hole capability, and durability helps maintain consistent thread quality while reducing tool changes and cycle times. Ideal for engineers and machinists working on hydraulic, automotive, and aerospace components where reliable thread milling matters most.
