Carmex Thread Mills Multifunction with coolant is a high-efficiency threading solution that combines drilling, chamfering, and thread milling into one tool, designed for shops that need fast, reliable UNC/UNF/UNEF/UNS threading in a single setup. With an MT7 shank and a size range of 5/16" to 7/16" bore at 18 TPI, it delivers precise threads while simplifying your manufacturing process.

• All-in-one operation: Drilling, chamfering, and thread milling are performed in a single pass, eliminating multiple tool changes and reducing cycle time.
• Through-tool coolant: Coolant is delivered through the tool for improved chip evacuation, better surface finish, and longer tool life on tough materials.
• Thread forms supported: Designed for UNC, UNF, UNEF, and UNS thread forms to cover a wide range of applications.
• Size range: Compatible with 5/16" to 7/16" holes and 18 threads per inch, enabling versatile use in common fastener sizes.
• Bi-directional threading: Works seamlessly for both right-hand and left-hand threads using the same tool, simplifying inventory and setup.
• Full profile thread: Produces a complete, accurate thread profile with strong engagement and consistent depth across productions.
• Hole compatibility: Suitable for both blind and through holes, making it adaptable to various component geometries.

This tool is engineered to reduce machining costs by minimizing tool changes and shortening cycle times without compromising thread quality. The robust design, combined with coolant-through capability and broad thread-form compatibility, helps maintain precision across a wide range of materials. Ideal for precision threading in aerospace, automotive, and general engineering applications where reliable, single-pass threading is essential.
