This carbide insert is designed for cutting internal threads when mounted on the required threading tool bar * An internal thread, also known as a female thread, undergoes machining using a single-lip threading tool. * Aside from this single-lip tool, a traditional threading cap could also help cut CNC internal threading * It is important to note that cutting internal threads occur only on concave surfaces.
