Tungaloy Corp. introduces T515, the new CVD-coated grade for cast iron turning.

T515, with specially designed substrate and coating structure, is a highly versatile CVD-coated grade most suitable for machining cast iron. The adhesion strength between the substrate and coating layer has been drastically improved in T515, which will strengthen chipping and peeling resistance, and offer stable machining. Excellent wear resistance in high-speed machining is another strength of this new grade.

The thickness of the alumina (Al₂O₃) layer has been increased by 1.7 times compared to our conventional products which provide remarkably long tool life. Also, Tungaloy's special surface technology, PremiumTec, plays an important role to improve surface finish, leading to strong resistance to chipping and edge-buildup.

To simplify the chipbreaker selection, 2 main types will be stocked: all-round type and flat-top type.

The new CVD-coated grade, T515, for cast iron turning delivers reliability and stability in the application area ranging from general to high-speed machining. Together with Tungaloy's existing T5100 series, T515 will complement all operations of cast iron turning and provide manufacturers in various industries with outstanding productivity.
