Tungaloy has announced the expansion of TungThread indexable threading tool series to include full profile threading inserts with the UN and UNJ profiles in AH8015 grade.
TungThread offers high-performance indexable threading tool solutions, extending over a broad range of threading applications from general parts that are machined in CNC lathes and small precision parts in Swiss-type automatic lathes to premium threading of oil-country tubular goods.
A physical vapor deposition-coated (PVD) cemented carbide grade, AH8015 features a hard, high-aluminum content multi-layer coating that is combined with a dedicated carbide substrate. The grade is said to provide the insert with a well-balanced wear and chipping resistance.
New AH8015 grade threading inserts now offer the UN and UNJ profiles. The UN, or unified thread, is most commonly used on bolts, nuts and a wide variety of other fasteners, while UNJ was developed to meet aerospace requirements for fatigue resistance. This expansion provides threading applications with long, predictable tool life, while keeping machining costs down, in not only steel and stainless steel, but also difficult heat-resistant superalloys.
