Carmex SRH Toolholder With Internal Coolant Bore - For Spiral Mill Threading Inserts - SRH15-1

The Carmex SRH Toolholder with Internal Coolant Bore is engineered for spiral mill-threading inserts, delivering smooth, high-efficiency cutting across a wide range of milling tasks. It’s a reliable choice for engineers, buyers, tradespeople, and shop-floor machinists who demand consistent results—from threading small components on compact mills to heavy-duty milling on high-power machines.

This spiral-fluted toolholder supports 1 to 9 inserts in a compact cutting diameter and uses a unique clamping method for optimal indexability, helping you minimize downtime during insert changes. Inserts are available in MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), providing a general-purpose option that works with all materials.

• Smooth high-feed cutting with spiral design: The spiral geometry enables a smooth cutting operation at high feed rates, reducing machining time and enabling versatile performance from small components to heavy-duty milling.
• Flexible insert capacity with reliable indexability: Spiral toolholders hold 1 to 9 inserts in a compact diameter, and the unique clamping method ensures optimal indexability for fast, repeatable insert changes and consistent results.
• Internal coolant bore for efficient cooling and chip control: The built-in coolant path helps keep inserts cooler during heavy cuts and improves chip evacuation, contributing to longer tool life and better finishes across threading, end milling roughing, and finishing.

By combining spiral cutting efficiency, flexible insert capacity, precise indexing, and an efficient coolant bore, the SRH15-1 helps you shorten cycle times, reduce vibration, and maintain tight tolerances. This translates to less machine downtime, fewer reworks, and more consistent parts—whether you're running precision threading on small parts or rugged milling on larger components.
