Carmex SRH Toolholder With Internal Coolant Bore - For Spiral Mill Threading Inserts - SRH45-6M

The Carmex SRH Toolholder with Internal Coolant Bore (SRH45-6M) is a precision mounting solution designed for spiral mill-threading inserts. Built for reliability on today’s shop floors, it enables smooth cutting, high feed rates, and reduced cycle times across a wide range of threading and milling tasks.

Whether you’re machining small components on a compact center or tackling demanding operations on a high‑power milling machine, this toolholder delivers consistent, workload-friendly performance. The internal coolant bore directs coolant through the holder to manage heat, minimize tool wear, and maintain outstanding surface finishes even on long, heavy cuts.

• Internal Coolant Bore for Efficient Cooling: Delivers coolant directly to the cutting zone, lowering temperatures, reducing built-up edges, and extending insert life for cleaner finishes.
• Spiral Fluted Design for Smooth Cutting: Enables high feed rates with reduced vibration and chatter, boosting productivity and achieving steadier, more accurate cuts.
• 1–9 Insert Capacity with Precise Indexing: Accommodates multiple inserts in a compact diameter and uses a robust clamping system for quick, repeatable index changes with minimal downtime.

When paired with MT7 sub-micron grade inserts with Titanium Nitride multi-layer coating (ISO K10–K20), the SRH45-6M system combines durability with precision across threading, end milling roughing, and finishing. This thoughtful combination helps you shorten setup times, reduce downtime, and consistently achieve high-quality results across materials and applications.
