Carmex MTB Solid Carbide Thread Mills with Through Coolant deliver precise internal threads in metric holes while optimizing chip evacuation and tool longevity. Built for shops that demand reliable, repeatable threading in challenging materials, these tools extend productivity without sacrificing quality.

• Through coolant bore: Delivers coolant directly through the tool to the cutting edge, improving chip removal inside the hole and reducing heat build-up for cleaner threads.
• Solid carbide construction: High-hardness substrate provides exceptional wear resistance and maintains thread form under demanding milling conditions.
• Metric thread sizes: Ready for internal threading in M27, M28, and M30 holes with a 3 mm pitch, aligning with common metric standards in precision components.
• MT7 shank: Compatible with MT7 tool holders for secure engagement, stability, and smooth high-speed milling performance.
• Optimized thread-milling geometry: Purpose-built flute and cutting-edge geometry designed for consistent thread quality, smooth exits, and minimal tool deflection.

The MTB line, leveraging the proven MT platform, advances thread milling by integrating through-bore cooling. This design enhances coolant delivery to the cutting zone, promoting better surface finish, reduced chatter, and longer tool life. Ideal for precision work in medical devices, automotive components, mold and die applications, and aerospace hardware where reliable internal threads and clean finishes matter.
