Blackrush Cast Iron Turning Grade
Ingersoll has applied innovative and creative technologies in developing BLACK-RUSH, a new series of cast iron ISO turning grades. CVD-coated grades TT7005 and TT7015 feature a stable substrate, strengthened coating layer and special post-coat treatment. The result is exceptional chipping resistance thanks to the superior bond between the substrate and the coating layer.
All BLACK-RUSH inserts feature a new coating technology which contains a special Al2O3 outer layer that maximizes hardness while providing thermal stability, an important consideration when machining cast iron especially at high cutting speeds. Following this coating process, a special surface treatment is applied that greatly reduces friction, cutting force and build-up on the insert cutting edge. The result is stable and consistent tool life and an excellent surface finish on the work piece.
TT7005 provides maximum wear resistance making it the ideal choice for both gray and ductile cast iron in high speed applications, while TT7015 delivers excellent all-around performance in these same materials while adding additional toughness for continuous to interrupted turning applications. Together, these grades provide a perfect combination of mechanical shock and heat/wear resistance in high speed machining of gray cast iron or ductile cast iron, allowing customers to achieve remarkable tool life and productivity in turning and boring applications.
