The Carmex CRC1618L48R Carbide Shank Toolholder with Internal Coolant is a precision vertical milling solution designed for use with CMT inserts. It targets shops that need accurate threads, grooves, and chamfers with repeatable results.

• Carbide shank: Rigid carbide core for enhanced stiffness and dependable tool positioning during demanding milling operations.
• Internal coolant bore: Integrated coolant channel delivers coolant directly to the cutting edge, improving chip control, surface finish, and insert life.
• Weldon shank mounting: Includes a Weldon-style shank for secure, repeatable clamping in milling setups.
• Ground-profile CMT inserts compatibility: Optimized for high-precision, ground-profile CMT vertical mill-thread inserts that deliver consistent performance at elevated machining parameters.
• One insert, dual thread direction: The same insert supports both right-hand and left-hand threads, reducing inventory and simplifying setups.
• Solid, accurate clamping: Robust clamping mechanism ensures full repeatability and minimal runout across multiple cycles.
• Chamfer insert compatibility: Chamfer inserts are available to extend capabilities without replacing the toolholder.

Designed for precision-focused metalworking, the CRC1618L48R toolholder enables reliable threading, grooving, and chamfering at higher speeds while maintaining tight tolerances and excellent surface quality. Its carbide shank, internal coolant, and secure Weldon mounting translate into longer insert life, improved part finish, and greater process stability—making it a dependable foundation for vertical milling with CMT inserts in professional shops.
