Carmex MTB solid carbide thread mills with through coolant are engineered for precise ISO metric internal threading in M16, M18, and M20 sizes. Built on the trusted MT platform, these tools deliver reliable thread quality, improved chip evacuation, and longer tool life in demanding production environments.

• Through-Coolant Bore: Coolant flows directly through the tool’s bore to the cutting edges, flushing chips and reducing heat buildup for deeper, consistent threads.
• Solid Carbide MT7 Grade: Sub-micron MT7 carbide with a multi-layer TiAIN coating provides high hardness, wear resistance, and extended tool life.
• Metric ISO Threading: Optimized geometry for metric threads M16, M18, and M20, delivering accurate pitches and clean thread profiles.
• Rugged MTB Design: Enhanced rigidity and durable construction built on Carmex MT technology to handle demanding machining conditions.
• Internal Coolant Delivery: Coolant is delivered through the flute bore for efficient cooling and effective chip removal during heavy material removal.

The combination of coolant-through capability and MT7 carbide delivers lower cutting temperatures, reduced tool wear, and more consistent thread quality—translating to fewer tool changes and shorter cycle times. Ideal for manufacturers tackling precision threaded components in automotive, aerospace, and industrial tooling, where reliable, repeatable threads matter most.
