Its tool tip is designed with an R-angle structure, which reduces local wear by increasing the contact area of the cutting edge. It combines the advantages of ball cutter surface machining and end mill flat machining. Suitable for rough cutting of molds, precision machining of flat surfaces, and milling of flat areas of large workpieces.
