The Carmex Steel Toolholder With Internal Coolant For CMT Inserts – SRC1210F is a precision vertical milling toolholder designed to house CMT inserts for threads, grooves, chamfers and more. Built for engineers, buyers, tradespeople and hobbyists alike, it provides reliable performance with direct coolant delivery and a solid clamping method that ensures repeatable results across multiple jobs. This toolholder pairs with Weldon shanks and includes a coolant bore to support demanding milling operations.

• Internal coolant bore for direct cooling: Delivers coolant straight to the insert during high-speed milling, helping control heat, improve surface finish, and extend tool life while simplifying chip evacuation.
• Weldon shank with rigid, repeatable clamping: The solid clamping mechanism minimizes runout and delivers consistent seating, reducing setup time and ensuring dependable performance job after job.
• Ground-profile inserts with universal threading: Provides high precision and excellent surface quality at demanding parameters, with one insert usable for both right- and left-hand threads and compatibility with chamfer inserts for broader applications.

Together, the SRC1210F toolholder delivers a dependable, versatile milling solution that helps you finish parts to spec, reduce downtime, and maintain consistent results across threaded, grooved, and chamfered features. The combination of direct coolant delivery, rigid clamping, and precision inserts supports efficient setups, longer tool life, and high-quality finishes on a wide range of components.
