Beschreibung
Zusammenfassung:	A combination cutting and burnishing orbital drilling tool may include an elongate tool body including a cutting end and extending along a longitudinal axis. The tool body may include a burnishing portion spaced from the cutting end and configured to induce residual stress in a side wall of a hole without removing material. The tool body may further include a cutting portion interposed between the cutting end and the burnishing portion. The cutting portion may be configured to remove material from a workpiece, thereby creating the hole, during an orbital drilling process.
