Abstract:
The flute terminus or carry out of a microdrill is located spaced from cross-sectional changes of the drill and away from such areas of stress concentration and permits a slight flexing of the drill to compensate for standard production environment in efficiencies such as spindle runout, nonperpendicularity of drill to workpiece and workpiece material which is not homogeneous.
