The increase of productivity is the major bottleneck in the automotive industries, as well as the constant demand for innovations and new technologies in order to perpetuate its business. In this way, the engineers are always seeking for alternatives to improve their manufacturing processes making them more competitive. However, the increase in productivity must be related not only to the quality of the products but also to the social and environmental issues. The machining area is always launching new cutting tools with new geometries and better tool coatings. This research focus on the investigation of new cutting tools applied on the manufacturing process of safety systems for the automotive industry. The sleeve machining sector of pinion & valve assembly for steering system was investigated to compare the old tools with the new ones with Penta geometry considering the lean manufacturing concept. In 2009 the data showed a percentage increase of 185% for the valve sector productivity. It was verified that the sleeve machining time were reduced providing a 100% of productivity demanded. In addition, despite of the investments in new tools, there was a cost reduction for each sleeve, consequently increasing the annual gain for the installed capacity.
