The Carmex Thread Mills Multifunction with Coolant is a precision threading solution designed for machining shops that want to streamline production. It combines drilling, chamfering, and thread milling in one tool, delivering fast cycles and reliable results for metric threads.

  • All-in-one threading tool: Drills, chamfers, and mills threads in a single operation—eliminating multiple tool changes.
  • Coolant-through design: Built-in coolant capability protects cutting edges and improves chip evacuation for longer tool life.
  • Metric thread options: Supports common profiles including M16, M17, and M23 x 2 for versatile applications.
  • MT7 shank: Sturdy Morse Taper 7 shank delivers solid rigidity and stability in demanding machining conditions.
  • Full-profile threads: Produces complete thread geometry for accurate engagement and smooth assembly.
  • Bidirectional compatibility: One tool handles right-hand and left-hand threads without changing tooling.
  • Material versatility: Suitable for a wide range of materials, from common steels to tougher alloys, expanding its use across applications.

By enabling drilling, chamfering, and thread milling in a single operation, this tool reduces cycle times and machining costs while maintaining high performance. Its coolant-assisted design helps extend tool life and deliver consistent thread quality, making it ideal for high-volume production, assemblies with blind or through holes, and setups that require fast changeovers between thread sizes or directions. Designed for professionals who value accuracy, efficiency, and reliability in metric threading tasks.
