  One of the biggest problems of artisans , is notching the high speed steel roller is due to the inability to do this work, become high speed steel roller bearings are disposable. When the roller is placed on the production line, because of the retained austenite make it very hard. High speed roller used in this study is barely above 70 Shc. To notch this rollers, diamond tools, ceramic and CBN were tested. Our goal is to obtain the optimum machining parameters that it requires a high number of tests that are practically impossible. So in order to achieve optimal machining parameters with the lowest test, RSM method in Minitab software was used. After investigation we can say that diamond tools have not the ability to influence the level of high speed roller. Ceramic tools are able to machining HSS rollers, but in terms of time and cost, it is not good. CBN tools performed well in all tests and succeeded with the best cutting speed 25 m/min, 0.05 mm feed and 0.05 mm depth of cut at the time of 1080 seconds, in notching one caliber.
