The Carmex Thread Mills Solid Carbide - Internal & External Thread - BSPT - RC1/4, RC3/8 x 19 - MT7 is a versatile threading tool designed for precision and efficiency. Built for machinists and shops that need reliable BSPT and RC thread milling, this MT7 shank tool delivers consistent results across both internal and external threads.

• Material: Solid carbide construction for exceptional hardness, wear resistance, and long tool life in demanding threading applications.
• Flute count: 3–5 flutes to balance cutting efficiency with thread accuracy and smooth chip evacuation.
• Threading capability: Internal and external thread milling, enabling you to format both male and female threads with a single tool.
• Thread standards and sizes: Supports BSPT and RC threading profiles, specifically RC1/4 and RC3/8 x 19, with MT7 tooling for broad machine compatibility.
• Economic efficiency: Optimized flute geometry and carbide construction reduce cycle times and tooling costs while maintaining high-quality thread finishes.

Designed to streamline threading workflows, this MT-line tool delivers predictable performance from start to finish. The multi-flute design supports stable, precise thread formation, while the solid carbide body withstands repeated milling cycles. Ideal for small to mid-volume production and shops seeking a reliable, cost-effective solution for BSPT and RC threads, the Carmex MT7 thread mill helps you complete threaded features with fewer tool changes and tighter tolerances.
