Threading Grades
Grade SP4066 has the perfect balance between wear resistance and toughness, which means one insert can cover multiple applications. This new grade also enables longer tool life and is ideal for machining a variety of materials at elevated cutting speeds. See inch and metric grade descriptions.
Full Profile Threading Inserts
Full profile threading inserts will cut the complete thread form, including the crest. A separate insert is needed for every thread pitch and standard form. See our inch index and metric index to see our complete offering of thread forms.
Partial Profile Threading Inserts
Partial profile threading inserts are available in these two styles and thread angles: 60° Type (ISO and Unified) and 55° Type (British Standard Whitworth). Partial profile inserts cut wihtout machining the crest of the thread. The same insert can be used for a wide range of different thread pitches.
