Carmex MTB Solid Carbide Thread Mills with Through Coolant are built for professionals who demand precise, reliable internal threading in through-holes. Designed for metric applications, these MT7-taper tools deliver cleaner threads, longer tool life, and smoother production runs.

• Through-coolant bore: coolant is delivered through the tool’s bore to flush chips from the threading hole and keep cutting edges cool for stable, consistent cuts.
• Solid carbide construction: high rigidity and wear resistance ensure precise thread form and repeatable results in demanding materials.
• Metric threading options: available for internal M24 and M28 × 3 threads, enabling accurate fits in metric components.
• MT7 shank: compatible with standard Morse Taper 7 holders for secure mounting and reliable cutting performance.
• Internal thread milling capability: ideal for replacing tapping in through-holes, delivering accurate threads with reduced tapping steps and less vibration.
• Durability and life extension: the combination of through-coolant cooling and robust carbide enhances tool longevity and lowers replacement frequency in high-volume production.

These thread mills are engineered to deliver dependable, high-quality internal threads with minimal post-processing. The through-coolant design improves chip evacuation and heat management, supporting higher cutting data and more consistent thread finishes. With the MT7 shank, you get solid alignment and compatibility across a range of milling centers, making these tools a reliable choice for precision engineering tasks that require durable, metric thread milling in metal parts.
