Description
Carmex MTB Thread Mills are solid carbide tools engineered for precision internal threading with through coolant, designed for NPTF threads and MT7 machines. Built for shops that demand reliable chip evacuation, temperature control, and long tool life in tight, critical holes.
- Thread Size & Pitch: NPTF threads in the 1/4" to 3/8" range with 18 TPI, crafted for accurate, repeatable thread profiles in metal parts.
- Through-Coolant Bore: coolant is delivered through the bore to the cutting edge and routed through the hole, enhancing chip removal and regulating cutting temperatures for cleaner threads.
- Solid Carbide Construction: hard-wearing, rigid substrate that maintains tolerances under high-speed milling and demanding materials.
- MT7 Shank: compatible with a wide range of MT7 tool holders for stable performance and quick tool changes on compatible CNC machines.
- MTB Innovation Benefit: built on Carmex MTB tooling advances to maximize cutting efficiency, chip management, and tool longevity in through-coolant applications.
This combination delivers tangible advantages: smoother thread formation with consistent dimensions, fewer interruptions from chip buildup, and reduced tooling costs due to extended tool life. Ideal for manufacturing hydraulic fittings, piping connections, and other precision NPTF components, the Carmex MTB thread mills provide dependable performance, better surface finishes, and improved process reliability in demanding fabrication environments.
