The Carmex MTZ carbide thread mill with through-coolant is crafted for precise threading in through-holes, delivering coolant directly to the cutting edge for smoother, cooler, and more consistent results. Designed for shops that may not have external coolant systems, it provides reliable performance on 3/8-16 UNC threads using MT7 tool holders.

• Through-Coolant Flute Delivery: Coolant travels through the tool’s flutes directly to the cutting edge for superior heat management and chip control.
• Solid Carbide Construction: Tough, wear-resistant carbide body that maintains accurate thread profiles under demanding cutting conditions.
• Thread Size & Standards: 3/8-16 UNC threading with support for UNC/UNF/UNEF/UNS thread forms in through-hole applications.
• MT7 Morse Taper Shank: Robust MT7 shank provides secure seating and broad machine compatibility across CNC setups.
• Flute Geometry for Direct Chip Removal: Optimized flute design enables efficient chip evacuation in through-holes, reducing downtime and rework.
• Machine-Centric Versatility: Effective on machines without dedicated external coolant systems, expanding where and how you can produce precise threads.

By delivering coolant precisely where it’s needed, this thread mill helps achieve consistent 3/8-16 UNC threads with improved surface finish and tighter tolerances in through-holes. The carbide construction delivers reliable performance across tough materials, while the through-hole optimized design with direct chip removal minimizes chip buildup and cycle times. The MT7 shank ensures dependable tool seating on a wide range of CNC machines, making this Carmex thread mill a dependable choice for automotive, aerospace, and general engineering applications that rely on durable, accurate threaded features inside through-holes.
