Carmex Thread Mills Multifunction with coolant is a single, high-efficiency threading solution designed for machinists who want to streamline hole-making. It combines drilling, chamfering, and thread milling in one pass, making it ideal for production environments that demand fast cycle times and reliable threads in both blind and through holes.

• Thread forms supported: UN (UNC, UNF, UNEF, UNS) threads are accommodated, giving you broad compatibility across common standards.
• Size / pitch: 5/16 - 1/2 x 24 with MT7 shank for versatile use on standard milling machines.
• Multifunction capability: Drilling, chamfering, and full-profile thread milling are performed with a single tool, eliminating separate operations and tool changes.
• Coolant through tooling: Integrated coolant capability enhances chip evacuation, reduces heat, and extends tool life for demanding materials.
• Hole versatility: Suitable for both blind and through holes, with a consistent thread profile from the first cut to the last.
• Left- and right-hand threads: One tool handles both right-hand and left-hand threaded parts without changing tooling.
• Material range: Designed to cut a wide range of materials, supporting various alloys and grades encountered in production.

This multifunction thread mill is built for efficiency and accuracy in busy shops. By delivering drilling, chamfering, and threading in a single pass, it minimizes downtime, reduces tooling inventory, and helps you maintain tight tolerances on every part. The combination of coolant through the tool, full-profile threads, and compatibility with multiple UN thread forms translates to predictable performance, improved surface finish, and lower overall machining costs—especially in high-volume applications like automotive, aerospace, and general precision manufacturing.
