Grand high wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts
Grand high wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts.
Core Barrels are used to cut an annular ring in rock or concrete or reinforced concrete. The center core of the rock or concrete is usually crushed with rock auger. The most important advantage of a core barrel is that it assists to concentrate the torque and crowd force on a small ring of cutting teeth.
These Grand tungsten carbide insert bits are used to drill soft formation with low compressive strength and high drill ability, such as shale, clay, sandstone and soft limestone, etc.
