Shank adaptors - carburized and manufactured with tight tolerances and controlled straightness.

characteristic:

Button bits with 6tips, 7tips, 8tips 

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.
