In continuous cutting operation, the use of chip breakers has become virtually important and much effort has been put into the development of a wide range of breakers to suit a wide cutting condition. Unexpected chipping will occur on the minor cutting edge, when as insert that has proper chip breaking performance is under optimum cutting condition. Then, the effect of chip breakers on the wear and chipping of inserts have been experimentaly investigated. The progress of crater wear is studied in details with the contour observation of five different chip breakers. The main results obtained are as follow
