Description
Tapered Drill Rod
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 seven 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.

Describtion
Our factory can offer many kinds of drill bits, including chisel type bits, cross type bits, tapered drill rods and integral drill rods, mainly used for mining, coal cutting, tunneling, rock cutting in quarrying.
Integral Drill Steel is used by a hand held drill machine in Underground mining and for small hole drilling, equipped with small power rock drills, like Air leg rock drills, hand held rock drills, etc. It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Regarding Integral drill steels, the quality of a steel material and a tungsten carbide is very important to get good drilling performance.
According to different application, different lengths are available from 400mm to 5000mm usually.
