Discover Carmex's MTSB Mini Type through-coolant thread mills—the compact, solid carbide cutters built for precise threading in pre-drilled holes. Designed for UNC, UNF, UNEF, and UNS threads, these tools deliver reliable performance in tight tolerances and challenging materials.

• No. 10 x 32 thread size: miniature threading capability tailored for small-diameter holes while maintaining accurate thread profiles.
• Through coolant bore: internal coolant channel feeds high-pressure coolant through the tool into the pre-hole, washing chips away during the threading circle and cooling the cutting edge.
• Solid carbide construction: rigid, wear-resistant material for long tool life and consistent dimensional accuracy across multiple passes.
• MT7 shank: robust, stable interface for dependable performance on CNC machines.
• Mini MTSB design: compact geometry optimized for tight pockets and limited radial clearance without sacrificing threading quality.
• Thread type compatibility: suitable for UNC, UNF, UNEF, and UNS thread forms, covering common metric and imperial applications in metalworking.

The integrated through-coolant system not only improves chip evacuation but also significantly enhances heat management at the cutting edge. Expect cleaner thread surfaces, reduced thermal distortion, and extended tool life in production environments where repeatability and precision matter. Ideal for precision threading tasks in pre-drilled holes across a range of materials where coolant-assisted cutting is advantageous.
