The Carmex SRH Toolholder with Internal Coolant Bore is designed to house spiral mill-thread inserts, delivering reliable performance across a broad range of milling tasks. Ideal for shops that run everything from small-part work on compact machines to heavy-duty milling on high-power equipment, this toolholder keeps your threading and end-milling operations efficient and consistent.

Its spiral flute design supports 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures optimal indexability and repeatable positioning. The internal coolant bore helps keep tools cooler during heavy cuts, contributing to longer insert life and steadier performance. Inerts are available in MT7 Sub-Micron Grade with a Titanium Nitride multi-layer coating (ISO K10‑K20), a versatile general-purpose option that suits a wide range of materials.

• Flexible insert capacity with precise indexability: Spiral toolholders accommodate 1 to 9 inserts in a compact diameter, while the unique clamping method ensures quick, repeatable indexing for consistent results.
• Smooth cutting at high feed rates with reduced downtime: The spiral design enables fast, efficient cutting and minimizes vibration and chatter, helping you complete jobs faster with a cleaner finish.
• Durable, versatile inserts with proven coating: MT7 Sub-Micron Grade inserts with TiN multi-layer coating (ISO K10‑K20) provide reliable performance across materials for threading, roughing, and finishing.

The SRH32P-5 toolholder is built to streamline your workflow: it supports high-efficiency cutting, maintains stable indexing, and pairs with robust TiN-coated inserts to deliver consistent, high-quality finishes on threaded and milled features. This combination helps reduce downtime, improve throughput, and provide confident, repeatable results across a wide range of applications.
