Bullet teeth are specialized cutting tools utilized primarily in auger operations for drilling through tough soil, rock, and other challenging materials. Characterized by their streamlined, conical design, these teeth are engineered to penetrate efficiently and minimize the required drilling force. Their unique shape allows for optimal cutting performance while maintaining durability in demanding conditions.

(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.

Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.

Drilling rig is a tool used to directly mine stone. It drills through rock layers to extract stone or other stone works.
