The MTZ Carbide Thread Mills with Through Coolant from Carmex are precision threading tools designed for internal threads in through-holes. Built for reliability in demanding metalworking environments, these carbide mills deliver clean, accurate threads even when coolant access is limited.

• Through-Coolant Flute Design: coolant travels directly through the flutes to the cutting edge for efficient cooling, improved chip evacuation, and consistent thread quality.
• Carbide Construction: a solid carbide body provides high rigidity, wear resistance, and extended tool life under demanding threading operations.
• MT7 Shank: robust MT7 taper offers secure, repeatable toolholding compatible with standard CNC milling centers.
• Thread Forms Supported: engineered to cut UNC, UNF, UNEF, and UNS thread forms for versatile applications across industries.
• Through-Hole Threading with Direct Chip Removal: optimized geometry enables direct chip removal in through-hole threading, reducing clogging and improving cycle efficiency.
• Compatibility with Limited Coolant Setups: designed to perform effectively on machines without external coolant systems, increasing where and how you can thread.
• Size Options: available in 9/16 in and 5/8 in major diameters, with thread-size capability up to 1-5/8-18 for versatile internal threading needs.

These features translate to tangible benefits: precise, smooth internal threads with reliable repeatability, reduced heat build-up at the cutting edge, and longer tool life thanks to carbide’s wear resistance. The through-coolant delivery minimizes thermal distortion and enhances debris evacuation, leading to cleaner threads and improved surface finish. Whether you’re tackling aerospace-grade fasteners or automotive components, this Carmex MTZ thread mill helps you achieve consistent results, even in setups lacking dedicated coolant infrastructure.
