Carmex Thread Mills Solid Carbide - Fast Type - With Internal Coolant Bore - UN (UNC UNF UNEF UNS) - 3/8, 9/16, 5/8, 11/16 x 24 - MT8

The Carmex FMT/Fast MT solid carbide thread mills are designed for high-speed internal threading, delivering precise, repeatable threads with a focus on productivity. Built to handle UN family thread forms (UNC, UNF, UNEF, UNS) and offered with an MT8 shank, they’re ideal for shops tackling volume production and demanding materials.

• Multi-flute design: Large flute counts (5–8) reduce cutting times and improve chip evacuation for faster, smoother thread milling.
• Internal coolant bore: Integrated coolant channel enhances cooling and chip removal during deep or aggressive threading operations.
• Solid carbide construction: Rigid, wear-resistant substrate provides long tool life and consistent thread quality in tough materials.
• UN thread compatibility: Supports a range of thread standards (UNC, UNF, UNEF, UNS) for versatile applications.
• MT8 shank: Standard milling machine interface that fits a wide array of CNC centers and holders.
• Size offerings: Available in 3/8 x 24, 9/16 x 24, 5/8 x 24, and 11/16 x 24 to match common threaded needs.

These tools excel in high-production environments where fast cycle times and reliable thread accuracy matter. The combination of a high-flute count and an internal coolant bore translates to cooler cutting, reduced tool wear, and cleaner chips, enabling longer runs between tool changes. Whether you’re threading through steel, alloy, or other challenging materials, the Carmex Fast MT thread mills help you maintain tight tolerances and consistent thread profiles while boosting throughput.
