Carmex Steel Toolholder With Internal Coolant For CMT Inserts — SRC2018H is a rugged, steel toolholder designed for vertical milling with CMT inserts. It supports a wide range of operations, including threads, grooves, chamfers, and more, making it a versatile choice for production shops, job shops, and on-site maintenance. The assembly includes a Weldon shank and an internal coolant bore to help manage heat and deliver cleaner cuts.

Built around ground-profile CMT inserts, this holder delivers high precision and reliable performance even at demanding machining parameters. Its solid, accurate clamping method enables repeatable results across multiple parts, while the design supports the same insert for both right-hand and left-hand threads. Chamfer inserts are available to expand capabilities without changing tooling setups.

• Precise, repeatable clamping: Solid and accurate clamping method enables full repeatability across jobs, helping maintain tight tolerances and consistent results.
• Integrated coolant bore: Internal coolant improves heat management and surface finish, reduces tool wear, and simplifies chip control for longer tool life in tough milling and threading tasks.
• Versatile threading with right-/left-hand capability: A single insert handles both right- and left-hand threads, while ground-profile inserts deliver high precision and performance at higher machining parameters.

This toolholder is designed to streamline your vertical milling workflow: quick, dependable tool changes, consistent thread and groove quality, and reduced downtime thanks to reliable clamping and effective cooling. With the Weldon shank and internal coolant bore, you can push higher cutting parameters with confidence, achieving repeatable results across parts while protecting tool life and finish quality.
