Carmex MTB Solid Carbide Thread Mills with Through Coolant are precision tools built for professionals who demand consistent, high-quality threads in unified thread forms (UNC, UNF, UNEF, UNS). Designed for machines set up with MT7 tooling, this 1 in diameter, 8 TPI mill delivers reliable performance in demanding materials.

• Through-Coolant Bore: Internal coolant channels help flush chips out of the hole as you thread, reducing clogging and heat buildup for smoother cutting.
• Solid Carbide Construction: Rugged, wear-resistant carbide geometry provides longer tool life and stable performance in hard metals and stainless steels.
• MT7 Shank: Robust Morse Taper 7 shank ensures rigid seating in compatible CNC spindles for accurate, repeatable threading.
• UN Thread Form Compatibility: Specifically engineered to produce UNC, UNF, UNEF, and UNS threads with precision and consistency.
• Size and Pitch: 1 in diameter with an 8 TPI thread pitch, optimized for standard Unified thread specifications.
• Thread Milling Versatility: Ideal for internal thread creation in both through-holes and deep blind holes, minimizing tapping-related issues.

The MTB design targets two core benefits: superior chip control and extended tool life. By delivering coolant directly through the bore, it helps keep cutting temperatures down, preserves thread geometry, and reduces the need for multiple passes. The result is cleaner threads, smoother finishes, and lower tooling costs over time—especially in recurring production runs or when working with tougher alloys. This tool is well-suited for precision engineering applications where accuracy, repeatability, and reliability matter most.
