Carmex Thread Mills Carbide Mini Type - Metric - M1.6, M1.8, M2, M2.5 x 0.35 - MT7

Carmex Mini Thread Mills in carbide deliver precise metric threading in small-diameter holes, built for high-speed performance and long tool life. Designed for machinists and shops that need reliable internal and external threads in tight spaces, these mini mills excel where traditional taps struggle.

• Diameter range: Metric thread mills in M1.6, M1.8, M2, and M2.5 with a consistent 0.35 mm pitch.
• Material & coating: Sub-micron MT7 carbide with a Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for durability at elevated speeds.
• Tool geometry: Mini type with spiral flutes for smooth cutting action and efficient chip evacuation.
• Through-coolant: Coolant through the flutes enhances heat removal, especially in deep-hole threading.
• Cutting performance: Short profile reduces cutting forces and enables medium to high cutting speeds with shorter cycle times.
• Versatility: One tool capable of producing both internal and external threads across a wide range of pitches and materials, including hardened steels up to 45 HRc.
• Durability: Multi-layer coating and optimized geometry extend tool life in challenging materials and demanding cycles.

These carbide mini thread mills are purpose-built to cut clean, accurate threads quickly in deep holes, with coolant-assisted efficiency that minimizes wear. The combination of a rigid MT7 carbide, TiAlN coating, and a short, multi-flute design translates into reliable performance across a variety of materials—from softer alloys to hardened steels—while reducing the need for tool changes and lowering the risk of tap breakage. Ideal for aerospace, automotive, mold making, and precision assembly where compact tools and trustworthy thread profiles matter.
