>Multiple-Cutting-Edge Tools:
Multiple cutting edge tools have more than one cutting edge and usually achieve their motion relative to the workpart by rotating. Drilling and milling use multiple cutting edge tools. Figure 21.4(b) shows a helical milling cutterused in peripheral milling. Although the shape is quite different from a single point tool, many elements of tool geometry are similar.
