Learn more about Klarna
Engineered for precision thread milling, the Carmex MTB solid carbide thread mill with through coolant is built for UNC/UNF/UNEF/UNS threads in a 3/8 x 16 size. This MT7-shank tool is designed to deliver consistent, accurate threads while actively flushing chips through the bore for reliable cooling and flow.
- Thread compatibility: UN family (UNC, UNF, UNEF, UNS) for versatile applications
- Size: 3/8 × 16 for standard 3/8-16 threaded holes
- Through coolant: coolant channels run through the bore to the cutting edges, aiding chip evacuation and temperature control
- Material: Solid carbide for high hardness, wear resistance, and long tool life
- Shank: MT7 for rigid, high-performance toolholding
- Geometry: Optimized thread-milling flute design to produce clean, accurate thread profiles
- Construction: Precision-ground, rugged carbide body built to withstand production environments
The through-coolant design reduces heat buildup at the cutting edges, minimizes built-up edge, and keeps chips moving away from the thread path. This translates to smoother thread formation, fewer reworks, and extended tool life—ideal for high-volume production or precision-focused fabrication. Use this tool to achieve reliable thread quality in common metals and alloys, with the confidence that chip control and cooling are integrated into the cutting action. Its robust MT7 shank ensures solid stability in demanding machining setups, making it a practical choice for shops seeking consistency and efficiency in threaded features.
