The Carmex Steel Toolholder With Internal Coolant For CMT Inserts (SRC2525J) is a precision toolholder designed for vertical milling with CMT inserts. It supports a wide range of operations—from threads to grooves and chamfers—delivering repeatable, high-quality results in demanding workpieces.

Built for engineers, shop floors, and hobbyists alike, this toolholder combines a robust weldon shank with an integrated coolant bore and compatibility with CMT’s ground-profile inserts. It’s engineered to perform at higher cutting parameters while delivering excellent surface finish, and the same insert can be used for right- or left-hand threads, simplifying inventory and setup.

• Internal coolant bore: Delivers coolant directly to the cutting edge for cooler operation, improved chip control, and longer tool life with consistent results.
• Rigid weldon shank and repeatable clamp: Provides secure mounting and minimal runout, enabling fast, precise index changes and reliable repeatability across production runs.
• Ground-profile CMT inserts for precision: Enables high-precision threading, grooving, and chamfering with excellent surface finish even at elevated machining parameters.

This toolholder is designed to streamline your vertical milling workflows. By combining direct cooling, solid clamping, and high-precision inserts, it helps you achieve consistent part quality, reduce downtime, and shorten cycle times across a range of common milling tasks.
