Carmex Thread Mills Multifunction - With Coolant - UN (UNC UNF UNEF UNS) - 1/4 - 3/8 x 20 - MT7

The Carmex Thread Mills Multifunction with coolant is a precision CNC tool engineered to form internal threads in a single, streamlined operation. Designed for machinists and job shops, it replaces separate drilling, chamfering, and threading steps with one versatile tool, delivering faster cycles and lower manufacturing costs.

• Tool Type: Multifunction thread mill that combines drilling, chamfering, and thread milling in one pass for reduced setup and cycle times.
• Thread Forms Supported: Compatible with UNC, UNF, UNEF, and UNS thread patterns, and usable for both right-hand and left-hand threads.
• Size and Pitch: Cutting diameter range from 1/4" to 3/8"; thread pitch 20 TPI (1/4-3/8 x 20).
• Shank: MT7 shank for rigid tooling and compatibility with a wide range of CNC centers.
• Full Profile Thread: Delivers complete thread geometry in a single toolpath, ensuring consistent engagement and thread quality.
• Coolant Through: Integrated coolant capability enhances chip evacuation, heat control, and tool life during demanding operations.
• Applications: Suitable for both blind and through holes, and capable across a broad range of materials.

This multifunction approach helps you eliminate drilling-only operations and minimizes tool changes, translating to shorter cycle times and reduced machining costs per part. With support for multiple thread standards and the ability to handle both hand directions, it’s a versatile choice for complex assemblies, prototypes, and high-mix production. The coolant-enabled design further improves finish quality and tool longevity on tougher materials, making it a reliable all-in-one solution for precise internal threads.
