1) Button bits with 6tips, 7tips, 8tips, we do them according to customers' requirement. We can manufacture the following types AC 
2) 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 angle is normally used. Taper angles of 11 and 12-degrees are always used on modern drill rigs. For low impact rock drills and softer rock formations, and a narrow taper angle of seven degrees is used of. A 7-degree angle can also be used if button 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.
