getting to know the lead angle | cutting tool engineering

2019-12-13 · The lead angle is an angular dimension measured parallel to the cutting edge of the tool and to the face of the part being produced (Figure 1). The angle affects the way the tool performs, how it should be applied and how the finished part looks. Typical lead angles available in standard tools are 90°, 60°, 45° and 15°
