Carmex MTB solid carbide thread mills with through coolant are engineered for precise internal threading in DIN 40430 applications. Designed for high-precision shops, these tools deliver clean chips, consistent thread quality, and extended tool life thanks to coolant flowing through the bore.

• Through coolant bore: coolant is delivered directly through the cutter to flood the cutting zone, enhancing chip evacuation and reducing thermal stress during threading.
• Solid carbide construction: rigid, wear-resistant tooling that maintains thread accuracy under demanding production conditions.
• DIN 40430 compatibility: supports common PG sizes (PG9, PG11, PG13.5, PG16) for versatile internal threading in a single tool family.
• MT7 shank: robust mounting interface that provides secure, high-torque performance in standard milling equipment.
• MTB line innovation: part of the MTB thread milling family with bore-through cooling to boost reliability, reduce downtime, and improve surface finish over multiple runs.

By delivering coolant through the bore, these thread mills help prevent chip clogging, lower cutting temperatures, and sustain tighter tolerances. This means fewer reworks, longer intervals between tool changes, and a smoother production flow—ideal for medical, aerospace, and automotive components where precision threads and dependable performance matter most.
