Rock Drills For Canada Rock Drill Bits Sandvik Hardrock Directional Drilling
High air pressure bit of 140-HD55A, the bit face designs are convex face, for high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, and may reduce the load and wear on gauge buttons, but poor hole deviation control, but poor hole deviation control. The shape of the Carbide button shape gauge buttons and front buttons is domed/round button and parabolic-ballistic button respectively. The quantity both is 7. The domed/round button are usually used as gauge buttons of DTH bits, suitable for very abrasive and very hard formations. The parabolic-ballistic button is usually used as gauge buttons and front buttons of DTH bits, suitable for medium abrasive and hard formations.
High air pressure bit speed and deep depth, it can be used for drilling more complex materials. It can choose higher cutting speed, can drill harder materials, multi-layer geometric cutting end edge, improve drainage performance and maintain small cutting resistance. In addition to the commonly used right angle handles, it is available in a variety of shank types, suitable for a variety of drilling rigs, drilling machines. A high-performance alloy blade for alloy drills is selected to effectively reduce the chipping and maintain good wear resistance.
