Applications
Due to its massive build, the tool holder is particularly well-suited for roughing operations, where high cutting forces are standard. The 95-degree geometry supports the reliable turning of cylindrical inner contours as well as facing tasks. This makes the boring bar an excellent choice for manufacturing workshops relying on consistent material removal and high process stability in heavy-duty machining.
Special features
The defining characteristic of this turning tool is its solid claw clamping system. This design guarantees that the WN insert is held firmly in the pocket, eliminating torsional movement. Even under varying cutting loads during roughing, the exact positioning is maintained, which promotes uniform machining results and can positively support insert tool life.
