12 Degree Tapered Tungsten Carbide Mining Rock Spherical Drill Bits Taper Button Drill Mining Bit of 32mm diameter


According to the tungsten carbide insert, button bits can be divided into types of hemispherical, conical and parabolic button, etc.

Button bits with hemispherical button is for high bearing capacity and abrasive resistance while conical button and parabolic button are for high drilling speed and low abrasive resistance.


Product Description:

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 12degree 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.
