Meet the Carmex MTB Solid Carbide Through-Coolant Thread Mill—engineered for precise threading in UNC, UNF, UNEF, and UNS standards. Designed for machinists and shops handling demanding thread milling, it combines robust carbide performance with a smart through-bore coolant design for cleaner, longer-lasting results.

• Through coolant bore: Coolant is delivered through the tool body to flush chips and cool the cutting edges, improving throughput and extending tool life.
• Solid carbide construction: Hardened carbide core for exceptional wear resistance and reliable performance at higher speeds and feeds.
• MT7 shank: Precise, rigid MT7 connection for stable milling and repeatable tool engagement on standard machines.
• UN thread compatibility: Optimized to produce UNC, UNF, UNEF, and UNS threads with consistent geometry and finish.
• Cutting diameters: Available in 3/8" and 9/16" cutting diameters to suit common thread sizes and reach requirements.
• Threading capacity: Capable of producing threads up to 5/8"-24, enabling a wide range of fastener styles with a single tool.
• Precision geometry: Carefully engineered flute shape and edge prep designed for clean thread profiles and smooth chip evacuation at high speeds.

The MTB through-coolant thread mill helps you maintain consistent thread quality across parts and reduces downtime from chip buildup and heat-related wear. Its durable carbide construction and through-bore cooling deliver reliable performance in production runs, deep holes, and tight pockets, making it a practical choice for precision engineering and high-accuracy threaded features.
