    Lead angle is 90° to the helix angle between the helical tooth face and an equivalent spur tooth face. For the same lead, the lead angle is larger for smaller gear diameters. It is understood to be measured at the standard pitch diameter unless otherwise specified. A spur gear tooth has a lead angle of 90°, and a helix angle of 0°. See ...
