The Carmex CRC1218P Carbide Shank Toolholder with Internal Coolant is a precision milling solution designed for vertical milling with CMT inserts. Built to handle threads, grooves, chamfers, and more, it delivers repeatable accuracy and high-quality finishes in demanding production environments.

• Internal coolant bore: Through-tool cooling supports better heat management, cleaner chips, and extended insert life during high-speed milling.
• Weldon shank mounting: Secure, rigid attachment ensures stable tool seating and consistent performance job after job.
• Designed for CMT inserts: Ground-profile inserts provide high precision and excellent surface quality at elevated machining parameters.
• Right- and left-hand thread compatibility: The same insert can be used for both thread directions, reducing tool inventory and setup time.
• Solid clamping for repeatability: Robust clamping minimizes runout, enabling full repeatability across multiple parts and cycles.
• Chamfer insert options: Chamfer inserts are available to expand finishing capabilities directly within the same tool system.

By combining a carbide shank with an integrated coolant channel and precision CMT insert alignment, this toolholder delivers consistent, high-quality results on threading, grooving, and chamfering operations. The rigid, repeatable clamping and ground-profile inserts help you achieve tight tolerances and smooth surfaces at higher feeds and depths, while the right/left-hand thread compatibility simplifies setup and reduces tooling complexity. Ideal for shops that demand reliability, precision, and efficiency in vertical milling workflows.
