Carmex's MTSB Mini Type thread mills with through coolant are precision solid carbide tools designed for tiny, high-accuracy threading in tight pre-holes. Built for engineers and machinists who demand reliable micro-threading performance, these cutters deliver efficient cooling and clean chip control in demanding applications.

• Through coolant bore: Internal coolant channel delivers high-pressure fluid through the tool into the pre-hole, washing chips away during the threading circle and cooling the cutting edge at the source.
• Mini MTSB type: Compact design optimized for small-diameter threads, enabling access in restricted spaces without sacrificing rigidity.
• Metric thread: M1.4 x 0.3 threading with MT7 shank for secure toolholding and compatibility with common CNC systems.
• Solid carbide construction: High rigidity and wear resistance for long tool life and consistent thread quality across materials.
• Internal cooling efficiency: The coolant bore and through-tool delivery maximize heat removal and improve chip control in threading operations.

This combination of through-coolant capability and micro-thread geometry makes these Carmex cutters ideal for mold making, precision fixtures, medical devices, and other applications requiring accurate, clean M1.4 x 0.3 threads. By actively cooling the cutting edge and washing away chips, they help protect delicate materials and deliver dependable performance in high-precision environments.
