what is a backhammer?

A backhammer, particularly in the context of Down-The-Hole (DTH) drilling, is a specialized percussion tool designed to help free drilling components that have become stuck or jammed in a borehole. It is mounted directly into the drill string, typically between the rotation unit and the drill pipes.

Unlike the primary DTH hammer, which impacts the drill bit downwards to break rock, the backhammer is engineered to direct its impact force backwards or upwards. When a drill string or DTH hammer gets jammed—a common issue in challenging rock or fractured ground—the backhammer is activated by compressed air to deliver powerful, rapid, reverse-impact energy, often combined with vibrations and right-hand rotation, to loosen and retrieve the stuck equipment, thereby saving significant time and expense.

what is backhammer made of?

A backhammer is constructed from high-strength alloy steels, meticulously chosen to withstand the intense, repetitive percussive forces and torsional stress encountered during drilling, particularly when freeing stuck tools. The components that deliver the impact, like the piston and impactor, are typically subjected to specialized heat treatment processes, such as case hardening. This treatment creates an extremely hard and wear-resistant outer surface while maintaining a tough, shock-absorbing core to prevent brittle fracture and fatigue failures in demanding downhole conditions.

Key Components and Materials

Protective Barrel/Housing: This outer shell is generally made from high-quality steel alloys to contain the internal components and provide structural integrity under high pressure. This steel must possess high yield strength and resistance to external abrasion as it rotates within the borehole. Its durability is essential for protecting the sophisticated internal mechanism from the demanding operational environment, ensuring a long service life.
Piston and Impactor: These are the core elements that generate the powerful backward impact force, requiring them to be crafted from advanced, case-hardened alloy steels. The careful heat treatment yields a component with maximum wear resistance on the surface to handle rapid striking, combined with a tough interior structure to absorb the considerable shock loads without breaking.
Spindle and Connecting Threads: The parts that connect the backhammer to the drill string and rotation unit are made of strong, high-grade steel with precisely machined threads, often to API (American Petroleum Institute) specifications. This robust construction ensures that the hammer can effectively transmit not only the powerful reverse impact energy but also the high rotational torque required to loosen a jammed drill string.
Seals and Casing: Internal O-rings and high-performance seals are crucial for maintaining the necessary compressed air pressure to drive the piston and for preventing air leakage. The main hammer assembly may also include a plastic or metal casing that serves as a guide for exhaust air, often acting as a muffler to reduce operational noise while ensuring a clean exit for the air.

what is backhammer used for?

A backhammer, or DTH (Down-The-Hole) Backhammer, is a specialized percussion tool primarily used in drilling to free a jammed or stuck drill string . It is mounted above the main DTH hammer and works by delivering powerful, backward-directed impact energy and vibration up the drill string. This reverse impact helps loosen the tool and drill pipes from the borehole wall or from surrounding debris, saving time and preventing costly equipment damage and downtime on the job site.

Primary Uses

Freeing Stuck Drill Tools: The main function is to deliver powerful, reverse-directed impact blows to the top of the stuck drill string. This action effectively combines with upward pulling force and rotation to successfully break loose a down-the-hole hammer or drill pipes that have become tightly lodged in the borehole, which frequently happens in unstable or fractured rock formations.
Drilling/Withdrawing Casing: The tool can be mounted upside down in the drill string to direct impact downwards to drive casing or, conversely, used in its standard orientation to provide upward impact force. This versatility allows the backhammer to effectively withdraw casings that have become tightly seated or hammered down into the hole, proving invaluable for overburden drilling systems and for efficient casing recovery.
Breaking Up Obstacles: The combined effect of reverse percussion and vibration can be used to pulverize or break apart a small obstacle that may have caused the initial sticking of the drill bit. By repeatedly impacting the rear end of the drill string, the energy propagates down to the bit, helping to clear the obstruction, which allows drilling to continue and greatly reduces the risk of serious equipment damage.

why Choose our Backhammers?

Choosing our backhammers is an investment in minimizing costly downtime and maximizing your drilling productivity. Our tools are engineered with superior materials and design features to ensure you can quickly and reliably rescue your jammed drill string, keeping your project on schedule and protecting your valuable equipment from damage.

Key Reasons to Choose Our Backhammers

Unmatched Retrieval Power: Our backhammers feature a meticulously designed piston mechanism that delivers maximum reverse impact force on demand. This powerful upward blow, combined with necessary rotation, is the most reliable method for dislodging deeply stuck DTH hammers and drill pipes from complex or collapsing borehole formations.
Superior Durability and Service Life: Each unit is constructed from high-strength alloy steel that has been expertly heat-treated to resist extreme impact and abrasive wear. This robust design minimizes premature failure and wear and tear, ensuring the backhammer maintains its peak performance through countless operations, resulting in lower replacement costs over time.
Ease of Installation and Operation: The backhammer is designed for simple, quick installation directly into the drill string, typically between the rotation unit and the drill pipe. Its straightforward operation integrates with your existing air supply, offering an immediate, effective solution to a stuck-tool situation without requiring complex modifications or extensive on-site training.
Versatile Casing Applications: Beyond freeing stuck tools, our backhammers are functionally reversible, allowing them to be mounted in the drill string to provide powerful downward percussion for driving casing. This dual utility makes the tool essential for both emergency retrieval and planned overburden drilling projects, adding significant value and flexibility to your drilling operations.
