The Carmex CRC1625R Carbide Shank Toolholder with Internal Coolant is a precision milling accessory designed for vertical operations that use CMT inserts. It’s built for shops seeking repeatable accuracy, efficient cooling, and versatile threading, grooving, and chamfering capabilities in a single setup.

• Model / Shank: CRC1625R with a rigid carbide shank and integrated coolant bore for through-tool cooling.
• Shank Type: Weldon-style shank provides secure, repeatable seating in the milling spindle.
• Internal Coolant Bore: Through-bore coolant delivers coolant directly to the insert interface, improving heat management and chip evacuation.
• Insert Compatibility: Optimized for CMT Vertical Mill-Thread inserts with ground profiles for high precision and excellent surface finish.
• RH/LH Thread Flexibility: Same insert can be used for both right-hand and left-hand threads, reducing tooling inventory and setup time.
• Clamping & Repeatability: Solid, accurate clamping ensures consistent performance and full repeatability across passes.
• Applications: Ideal for threads, grooves, chamfers, and a broad range of vertical milling tasks when using indexable inserts.
• Chamfer Inserts: Chamfer insert options available to expand capabilities without changing holders.

With the CRC1625R, you gain reliable toolholding that supports higher machining parameters while preserving surface quality. The ground-profile inserts deliver precise geometries for clean threads and sharp chamfers, and the through-coolant design helps extend tool life by minimizing heat and wear. This setup is especially beneficial for shops that need fast changeovers, consistent repeatability, and the flexibility to tackle multiple milling operations with a single, robust toolholder.
