The global demand for high-precision 0.87" (22mm) drilling tools has reached an all-time high, driven by the expansion of infrastructure projects and the intensifying search for mineral resources. As a critical specification in rock fragmentation, 0.87" components—particularly tapered drill rods and shank adapters—are the backbone of light-duty to medium-duty drilling operations. These tools provide the necessary balance between portability and structural integrity, making them indispensable for pneumatic and hydraulic rock drills used across Europe, North America, and emerging markets in Asia.
Modern mining is shifting towards precision and automation. The trend involves integrating high-grade tungsten carbide with superior fatigue-resistant steel to extend the lifespan of 0.87" tools, reducing downtime in remote quarry sites.
Global enterprises now prioritize E-E-A-T compliant manufacturers. Reliability isn't just a buzzword; it’s a requirement. Suppliers must provide consistent metallurgical quality and precise threading to ensure compatibility with rigs like Atlas Copco or Sandvik.
From the granite quarries of Norway to the gold mines of South Africa, 0.87" drilling tools are applied in specialized tunneling, bolting, and dimensional stone cutting, where accuracy is paramount to project safety.

SHANDONG KAT DRILLING TOOLS stands as a titan in the Chinese industrial landscape. As one of the most professional manufacturers of rock drilling tools, our overall strength leads the industry nationwide. We specialize in the R&D and production of over 500 varieties of tools, ranging from 0.87" tapered systems to heavy-duty DTH bits.
Our facility integrates advanced heat treatment processes and CNC machining, ensuring that every shank adapter and button bit meets rigorous international standards. We are not just a factory; we are a strategic partner for mining operations worldwide, providing the reliability required for the world's toughest environments.
Special drilling tool equipped with polycrystalline diamond compact (PDC) cutters for mineral exploration.
Internal combustion engine rock drill featuring drilling, cleavage, bruising, and tamping functions.
Reliable power transmission components engineered for the most demanding mining and quarrying environments.
As we look toward the 2030 industrial horizon, the role of China 0.87" drilling tool manufacturers is evolving from simple component suppliers to integrated solution providers. The incorporation of IoT sensors in larger rigs requires that even the smallest consumable—the drill rod or bit—performs with absolute predictability. Our factory is at the forefront of this shift, utilizing vacuum-heat treatment and specialized surface hardening to ensure that our tools withstand the extreme percussive forces of modern high-frequency hydraulic drifters.
For global procurement officers, the decision to source from China is no longer just about cost-efficiency. It is about accessing a robust supply chain that can deliver high-quality R32, T38, and T45 threaded tools with shorter lead times than traditional European counterparts. By choosing Shandong KAT, you are investing in 40 years of metallurgical expertise and a commitment to excellence that powers infrastructure projects from the deepest tunnels to the highest quarries.
