6” Down-The-Hole (DTH) hammers

---

The SHANDIKE line of 6” Down-The-Hole (DTH) hammers leverages proven technology to offer exceptional performance at the highest levels compared to other drills available in the market. These tools are versatile and highly suitable for a wide array of drilling applications, encompassing residential geothermal installations, production quarry drilling, seismic exploration drilling, and small-scale construction drilling projects.

Within the SHANDIKE range of 6” hammers, customers can choose from several popular shank options: the QL60 shank, which is widely used and highly regarded; the DHD 360 shank, known for its robustness and reliability; and the SD6 shank, another trusted variant.

SHANDIKE has incorporated patented features into these hammers to maximize energy output while simultaneously minimizing the need for maintenance and service. By reducing the number of internal components, the complexity of service and maintenance requirements is greatly decreased. The valveless, high-frequency design of these hammers ensures a smooth and consistent operation, which further enhances their reliability and durability.

Each hammer features a hardened wear sleeve that provides superior wear resistance, even in the most abrasive and demanding drilling conditions. The multi-start threads on both the backhead and chuck make coupling and uncoupling of the hammer quick and easy, saving time and effort on the job site.

Additionally, the unique internal mount system eliminates the need for wear shims and special assembly tools, simplifying the installation and setup process. All critical internal components have undergone heat treatment under strict control, ensuring they are resilient and capable of withstanding the stresses and rigors of constant use, thereby maximizing the tool’s overall longevity and service life.

In summary, the SHANDIKE range of 6” DTH hammers combines proven technology, versatility, reliability, and advanced design features to deliver outstanding performance across a variety of drilling applications.
