T515 grade, with cemented carbide substrate and coating, is versatile and suitable for cast iron turning. The adhesion between the substrate and the coating enables it to deliver strong resistance to chipping and flaking, thus offering more stable machining.

By thickening the alumina (Al2O3) layer by 1.7 times, it has improved the wear resistance in high-speed machining.

PremiumTec, Tungaloy’s original surface treatment technology, improves the surface smoothness of the coating for resistance to chipping and built-up edge.
