How to choice the taper degree?
 
Different rock formations and rock drills require different taper angles. When drilling with high impact hydraulic rock drills in medium-hard to hard and abrasive rock formations, a wide taper angle is normally used. Taper angles of 11 and 12-degrees are normally used on modern drill rigs.
 
For low impact rock drills and softer rock formations, a narrow taper angle of 7 degrees is used. A 7-degree angle can also be used if bit spinning is a problem when using 11 and 12-degree equipment.
 
In addition, a 4,46 degree angle is ideal for soft rock when you're using pneumatic or hydraulic drill rigs - to prevent bits from spinning or becoming detached.
 
Generally, the light-duty rock drill uses 7 taper or smaller taper angle, the heavy-duty rock drill mainly uses 12 taper angle.
