The Carmex MTZ carbide thread mill with through-coolant is designed for through-hole threading, delivering coolant directly to the cutting edge for cleaner, more efficient performance. Built for reliability in UNC/UNF/UNEF/UNS thread forms, it combines rugged carbide durability with innovative cooling to keep threads precise from start to finish.

• Thread form compatibility: Supports 1/2 x 13 UNC/UNF/UNEF/UNS thread standards for versatile through-hole applications.
• Through-flute coolant delivery: Coolant is channeled through the tool’s flutes to the cutting edge, enhancing cooling and chip evacuation.
• Carbide construction: High-hardness carbide body provides long tool life and maintains accuracy under demanding cutting conditions.
• MT7 shank: Standard MT7 interface for secure toolholding and broad machine compatibility.
• Designed for through-hole threading: Optimized geometry supports direct chip removal, improving throughput and reducing finishing passes.
• Machine versatility: Ideal for setups without external coolant systems, expanding where and how you can machine threaded holes.

This thread mill enables higher internal threading efficiency with dependable surface finish and burr control. Use it for through-hole components in steel, stainless, or other alloy workpieces where clean, accurate UNC/UNF threads matter—whether in aerospace, automotive, or general precision machining. Its through-coolant design helps manage heat and chip flow, delivering consistent results across multiple parts and setups.
