In production, cutting tool is necessity tool for machining Process. It gives accuracy and surface finish by doing cutting action. The tool must be strong and having withstand wear resistance and produced more component for long period. During production of metal, machining is an important process which helps to gain good accuracy and shape. The life of carbide cutting tool is increased by giving coating. Coatings like TiN, Al2O3, TiN/ Al2O3 and TiC/ Al2O3 /TiN respectively.
