Description
The Carmex Internal Multiple Threading Insert Holder SR0100E40-4 is a precision mill-thread tool holder designed for internal threading with carbide inserts. Built for CNC milling environments, it enables fast, multi-insert threading with dependable stability.
- Insert capacity: Holds 4–8 carbide threading inserts per holder for efficient, multi-tooth cutting.
- Compatibility: Part of Carmex's Mill-Thread line and designed for internal applications only.
- Model: SR0100E40-4
- Tooling economics: More cost-effective than traditional taps and dies for internal threading operations.
- Machining technique: Supports internal threading via CNC milling with helical interpolation to form precise threads.
The holder is built to maximize productivity by spreading wear across multiple inserts and enabling higher cutting speeds. It’s ideal for shops performing high-volume internal threading on parts like housings and threaded bores, where consistent thread quality and reduced downtime matter most.
