The ones our customers buy most.Description
The Carmex SRC1618G Steel Toolholder with Internal Coolant is a precision mounting solution for vertical milling that uses CMT inserts. It’s designed for engineers, machinists, and shops tackling threads, grooves, chamfers, and more with a single, reliable tool system. The internal coolant bore delivers coolant directly to the cutting edge, helping control heat and improve surface finish on demanding jobs.
Engineered for high-parameter machining, this toolholder uses ground-profile CMT inserts for high precision and dependable performance. A solid, accurate clamping method ensures full repeatability across runs, and the same insert can be used for both right- and left-hand threads, simplifying setup and inventory.
- Internal coolant bore for direct edge cooling: Delivers coolant through the toolholder to the insert, reducing heat, extending tool life, and improving surface finish during high-speed milling.
- Solid weldon shank with precise, repeatable clamping: Ensures secure seating with minimal runout, delivering consistent performance across multiple parts and cycles.
- One insert for right- or left-hand threads: Streamlines setup and inventory, enabling quick changes between threading directions without swapping inserts.
This toolholder simplifies demanding vertical milling tasks by pairing reliable clamping, targeted cooling, and threading flexibility in a single assembly. Expect longer tool life, smoother finishes, fewer delays from tool changes, and consistent results across parts, whether you’re producing threads, grooves, or chamfers.
