 Different rock formation and rock drills require different taper angles. When drilling with high impact hydraulic rock drills in medium-hard to hard and abrasive rock formation, a wide taper angles is nomally used. Taper angles of 11° and 12° are normally used on modern drill rigs. For low impact rock drills and softer rock formation, a narrow taper angle of 7° is used. A 7° can also be used if bit spinning is a problem when using 11° and 12° equipment.
