The Carmex Steel Toolholder With Internal Coolant For CMT Inserts - SRC1618H is a versatile vertical milling toolholding solution designed to work with indexable CMT inserts. It enables threading, grooving, chamfering, and more with consistent accuracy, making it a reliable choice for shops, engineers, and technicians who demand dependable performance on demanding milling tasks.

The combination of ground-profile inserts and a solid clamping system delivers high precision and excellent surface quality, even at higher cutting parameters. Built to accommodate right- or left-hand threads with a single insert, the toolholder also includes a Weldon shank and an internal coolant bore to support efficient coolant delivery and stable operation across multiple cycles.

• Internal coolant bore for direct cooling: Delivers coolant precisely where it’s needed at the cutting edge, helping control heat, extend insert life, and improve finish on vertical milling operations with CMT inserts.
• Solid, accurate clamping for repeatable results: Rigid, repeatable engagement keeps tool position consistent from part to part, reducing setup time and ensuring reliable performance across runs.
• One insert for both right- and left-hand threads: Provides flexible threading capability with fewer tool changes, simplifying setups and lowering inventory needs.

This toolholder helps streamline milling workflows by delivering stable, repeatable performance with minimal setup effort. With internal coolant, a robust Weldon shank, and compatibility with CMT inserts, it supports longer tool life, cleaner machining, and precise generation of threads, grooves, and chamfers—across both right- and left-hand operations—while maintaining high surface quality on demanding parts.
