Thread inserts – are used for turning internal and external threads. The inserts are manufactured in geometry for a specific type and outline of the thread. Parameters determining the type of threading insert: Plate 16 ER 3 ISO Side length: 16mm | Insert type: external metric thread | Thread Pitch: 3mm | Thread profile: full ISO Inserts, apart from the division into internal and external threads, can be divided into those with: full profile – they precisely shape the entire outline of the thread, including the crests. area on which the thread to be cut does not have to be precisely prepared for machining. Incomplete profile – they do not machine the crests of the thread, therefore the surface for the thread must be performed accurately.
