Engineered for high-precision internal threading, Carmex's Solid Carbide Thread Mills with Through-Coolant deliver reliable, consistent threads in metric M20 x 2.5 holes. Designed for MT7 tooling systems, this tool combines carbide durability with efficient chip management for demanding machining environments.

  • Through-Coolant Bore: coolant is delivered through the bore to the cutting zone, promoting effective chip evacuation and cooler operation for deeper holes and tougher materials.
  • Solid Carbide Construction: premium carbide offers exceptional hardness and wear resistance, supporting precise thread profiles and longer tool life.
  • Metric Thread Size: specifically engineered for M20 x 2.5 internal threads, enabling accurate, repeatable thread geometry in metal parts.
  • MT7 Shank: compatible with standard MT7M/MT7 CNC holders, ensuring broad integration with common milling centers and setups.
  • Optimized Cutting Geometry: designed for stable thread milling performance, delivering clean thread starts, consistent pitch, and reduced burr formation.

This through-coolant thread mill is ideal for production runs and precision shops aiming to improve uptime, reduce rework, and achieve high-quality internal threads in metals ranging from alloys to tougher steels. By combining chip control with durable carbide, it helps you achieve reliable thread integrity, smoother finishes, and longer tool life in challenging drilling and milling applications.
