WHY CHOOSE PULANKA

Top Hammer Drilling

Top Hammer Drilling is a widely used technique in rock drilling, known for its efficiency and versatility. This method relies on a hammer mechanism positioned at the top of the drill string to deliver rapid, high-frequency impacts. These forces are transferred through the drill rods to the bit, which breaks the rock while rotating to ensure smooth and effective cutting. It’s commonly applied in industries such as construction, mining, quarrying, and tunneling and a ideal for tasks like blast hole drilling, rock bolting, and ground stabilization. Its modular design offers adaptability, making it suitable for a range of drilling environments, whether on the surface or underground. This flexibility has made it a popular choice for professionals in the field.

Down The Hole Drilling

Down-the-Hole (DTH) Drilling is a percussive drilling method used primarily in mining, quarrying, and construction for drilling hard rock formations. It is known for its efficiency and accuracy in creating deep, straight holes.

Down The Hole drilling: Hammer is at the bottom (near the bit), reducing energy loss (better for deep holes).

Jack Hammer Drilling

Jack hammer drilling is widely used in mining, tunnel excavation, and construction. Optimizing the transmission of impact and rotational force through taper design to improve drilling efficiency. Under different rock conditions, our tapered drilling tools exhibit good adaptability, can significantly reduce energy loss. Besides, cutting picks are widely used in coal and mineral mining, infrastructure construction, and other fields. Our cutting picks have outstanding wear resistance and impact resistance, which can improve the efficiency of coal and rock crushing and operation, shorten the construction period, and reduce production costs. Overall, tapered drilling tools are an ideal choice for modern engineering operations due to their excellent performance in facilitating efficient and high-quality drilling operations.
