The Carmex SRH Toolholder With Internal Coolant Bore (SRH23M-2) is a precision mounting solution designed for spiral mill-thread inserts. It’s built for engineers, machinists, and production shops that demand consistent threading and milling performance with direct coolant delivery to the cutting edge.

Whether you’re finishing small components on compact machining centers or tackling demanding milling on high-power machines, the SRH23M-2 keeps cutting efficient, cool, and stable for reliable results across a wide range of parts.

• Internal coolant bore for direct edge cooling: Delivers coolant straight to the cutting edge, improving chip control, reducing heat buildup, and extending insert life for more consistent threading and milling performance.
• Spiral flute design for high-speed, smooth cutting: Enables higher feed rates and shorter cycle times while minimizing vibration and chatter, helping you achieve clean threads and better surface finishes.
• Unique clamp for optimal indexability: Ensures precise, repeatable insert positioning and secure seating, with compatibility for MT7 Sub-Micron TiN-coated inserts (ISO K10–K20) to cover a broad range of materials.

By combining direct coolant delivery, efficient spiral cutting, and dependable indexing, the SRH23M-2 streamlines production, reduces cycle times, and delivers repeatable threading results across varied workloads—from small-batch parts to heavier milling tasks—without sacrificing accuracy or finish.
