Carmex MTB solid carbide thread mills with through coolant are engineered for precise metric internal threading. Designed for production environments and MT7 spindles, they deliver reliable chip control and extended tool life through coolant-assisted threading.

• Through-coolant bore: Delivers coolant directly to the cutting edges, improving heat management and flushing chips from deep or blind holes for cleaner, more reliable threads.
• Solid carbide construction: Rigid, wear-resistant material that maintains dimensional accuracy at high speeds and across long production runs.
• Metric thread sizes: Optimized for M12 and M14 × 0.75 pitches, enabling precise, standard-form internal threads for common fasteners.
• MT7 shank: Robust drive with broad compatibility to common CNC tool holders, ensuring stable milling performance.
• Optimized cutting geometry: Carefully engineered flute arrangement and cutting angles to minimize chatter and produce consistent thread profiles with smooth breakout.

The through-coolant design not only keeps temperatures lower at the cutting edge but also enhances chip evacuation, reducing the risk of built-up edge and extending tool life. This translates to more reliable thread quality, less rework, and higher productivity in high-speed machining or serial production. Ideal for internal threading tasks where coolant access and stable, repeatable results matter, these tools help you achieve accurate M12 and M14 threads with greater process efficiency and lower cost per thread over time.
