The Carmex MTB Thread Mills are a solid carbide threading solution designed for professionals who demand precision, durability, and efficient chip evacuation in BSP/BSF applications. This through-coolant variant with MT7 compatibility is built to deliver clean, accurate G (55 Degree) threads in demanding materials.

  • Through-Coolant Bore: Internal coolant channels feed directly to the cutting edges, flushing chips from the hole and helping maintain consistent temperatures for better thread quality.
  • Material: Solid carbide construction provides high rigidity, wear resistance, and long tool life in metals such as steel, stainless steel, and other hard alloys.
  • Thread Geometry: 55-degree cutting profile optimized for G BSF/BSP thread profiles, ensuring precise thread forms with tight tolerances.
  • Thread Size / Interface: G1/4 x 19 threading with MT7 shank compatibility for secure tool seating and stable feed during milling.
  • MTB Line Technology: Built on Carmex’s MTB innovations, offering dependable performance, durability, and predictable results in repetitive manufacturing scenarios.

This through-coolant thread mill not only improves chip clearance and heat management but also contributes to longer tool life, reducing downtime and tooling costs. Whether you're performing internal or external thread milling, this tool is well-suited for production runs, prototypes, or repair work that requires reliable BSP/G-thread accuracy. The combination of carbide hardness, optimized geometry, and coolant-assisted operation translates to consistent thread quality, smoother finishing passes, and better overall machining efficiency.
