The Carmex Steel Toolholder With Internal Coolant For CMT Inserts - SRC1612H is a robust vertical milling toolholding solution designed to securely hold CMT inserts and deliver consistent, high-quality results in threads, grooves, chamfers and more. It’s built for engineers, machinists, and maintenance teams who need reliable performance in demanding milling operations.

Vertical milling indexable inserts and toolholders enable a wide range of operations—from threads and grooves to chamfers. Ground-profile inserts provide high precision and excellent performance, even when pushing parameters to achieve high surface quality. The toolholder uses a solid, accurate clamping method to enable full repeatability, and the same insert can be used for right- or left-hand threads. The assembly includes a Weldon shank and an internal coolant bore, and chamfer inserts are also available.

• Ground-profile inserts for high precision: Precise geometry delivers accurate threads, grooves and chamfers with excellent surface finish, even at higher machining parameters.
• Solid, accurate clamping for full repeatability: Reduces runout and ensures consistent results across parts; the same insert works for right- or left-hand threads.
• Weldon shank with internal coolant bore: Easy mounting with reliable coolant delivery to the cutting edge, improving tool life and cutting performance.

This toolholder provides a dependable, easy-to-integrate solution for vertical milling with CMT inserts. By combining precise inserts, secure clamping, and integrated cooling, it helps you maintain tight tolerances, achieve cleaner finishes, and reduce downtime across production runs.
