The Carmex SRH Toolholder With Internal Coolant Bore (SRH17-2) is designed for spiral mill-threading inserts. It covers a wide range of milling tasks—from precision work on small components in compact machining centers to heavy-duty production on high-power mills.

Its spiral design enables smooth cutting at high feed rates, helping to reduce machining time while delivering consistent results. The toolholder accommodates 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability and repeatable performance in threading, end milling, roughing, and finishing.

• High-efficiency spiral cutting: Smooth cutting at high feed rates, reducing machining time and boosting productivity across both small-component work and heavy-duty milling.
• Flexible insert capacity and precise indexing: Holds 1 to 9 inserts in a compact diameter with a unique clamping method that ensures reliable index positioning for repeatable threading and milling results.
• Durable MT7 TiN-coated inserts for broad material support: Sub-Micron MT7 inserts with Titanium Nitride multi-layer coating (ISO K10-K20) provide versatile performance across a wide range of materials.

This toolholder supports efficient, repeatable threading and milling operations across materials and job sizes, helping you maintain consistent finishes and reliable results. The spiral design reduces vibration and chatter, improving surface quality and reducing rework, while the flexible insert configuration streamlines setup and changeovers for smoother, more productive workflows.
