In modern high-impact infrastructure construction, geotechnical exploration, and global mining operations, the efficacy of extraction machinery relies heavily on the wear-resistance of down-the-hole (DTH) and top-hammer drilling interfaces. Carbide Tipped Drill Bits represent the baseline of structural resistance, engineering performance, and mechanical uptime. Designed with premium tungsten carbide (WC-Co) composite matrices, these bits operate under extreme shear, impact, and high-frequency compressive stresses.
Currently, the international industrial demand for rock drilling tools is experiencing a major transition towards high-durability, smart-alloy tools. Driven by infrastructure expansion, green mining initiatives, and deep geological exploration projects across North America, the Middle East, and Sub-Saharan Africa, procurement divisions are shifting away from cheap alternatives. They are choosing partners that display deep metallurgical control and vertical manufacturing capability.
We boast over 40 years of specialized drilling tool manufacturing experience. Every structural development and metallurgical insight is directly built into our tools to ensure maximum field performance.
We optimize each tooling component to deliver exceptional penetration rates. For our clients, this translates directly to superior hole quality, reduced fuel consumption, and lower drilling costs.
Operating as a leading rock drilling tool manufacturer in China, our state-of-the-art sintering and CNC machining technologies give you a decisive advantage over standard market offerings.
Our catalog features complete systems for both tophammer and DTH operations, supporting projects from underground tunneling and surface mining to water well drilling and civil works.
Our factories control WC grain growth during the sintering phase. Utilizing vacuum furnace systems, we ensure a uniform cobalt distribution, balancing toughness (to resist chipping) and hardness (to resist abrasive wear).
We subject shank adapters and rod joints to carbonitriding and surface blast treatments. This builds high residual compressive stresses that counter high-frequency cyclical bending waves from hydraulic hammer impacts.
To reduce wear on the bit face, we configure flushing holes using fluid dynamics models. This ensures rapid debris clearance, preventing regrinding of rock dust and significantly extending the bit's operational life.
Our technological development roadmap focuses on zero-defect automated forging and the integration of cobalt-free binders to address raw material supply shifts and environmental regulations. By using advanced laser cladding and automated CNC machining center arrays, Shandong Kat ensures our tooling dimensions stay well within precision tolerances (+/-0.02mm), ensuring total compatibility with global drilling platforms like Epiroc, Sandvik, and Furukawa.
In challenging formations like quartz-rich granite and abrasive hard ores, our button bits and integral rods deliver reliable cutting paths. This reduces the risk of in-hole tool shearing and protects high-value drilling equipment.
For bridge foundations, high-rise piling, and highway excavations, our shank adapters and large-diameter reaming bits provide the stability and straightness required for precise deep drilling.
Designed to handle changing geological layers, our DTH hammers and DHD series button bits maintain high penetration rates in soft soil, clay, and hard stone strata alike.
Designed with high-quality polycrystalline diamond compact cutters to deliver fast penetration and clean core extraction in challenging exploration targets.
A self-powered system ideal for remote field environments. Performs drilling, cleavage, tamping, and chiseling without requiring an external compressor.
High-performance, vertical, water-cooled, 4-cycle turbocharged diesel engine. Built for reliable power delivery on modern rig chassis.
Featuring advanced screw element technology and high-torque engine configurations. Engineered for steady pressure supply during deep pneumatic DTH drilling operations.
Precision-manufactured couplings that maintain alignment and prevent thread damage, ensuring efficient power transfer through the drill string.
A critical component optimized for self-drilling anchor systems, designed to handle demanding geological consolidation processes.
Premium R32 connection interface equipped with strategically arranged carbide buttons for consistent penetration and reliable hole straightness.
High-precision spline designs that protect drifter components and reduce wear, ensuring smooth operation in challenging conditions.
Operating from Shandong, the center of China's premium metallurgical industries, our production facility benefits from integrated supply chains. With local access to high-purity tungsten reserves and specialized heat-treatment processing, we maintain steady, high-quality production even during volatile global market shifts.
Our integrated approach controls the entire manufacturing journey: from raw tungsten ore processing and alloy sintering to precision CNC machining and carbonitriding. This vertical integration allows us to keep lead times short, maintain consistent quality, and support custom tooling runs for specialized mining operations.

SHANDONG KAT DRILLING TOOLS is a leading manufacturer of rock drilling machinery and accessories in China. Recognized for our comprehensive technical capabilities, we lead the domestic industry in research, development, and production capacity.
Our state-of-the-art facility produces over 500 varieties of premium drilling tools, specializing in high-performance rock drilling equipment, specialized mining bits, and down-the-hole accessories. Serving exploration, water well, quarrying, and mining sectors worldwide, KAT is committed to field safety, operational efficiency, and long tool life.
Our factories implement strict quality control systems that meet global standards. We focus on structural integrity, material traceability, and thorough inspection processes:
We select premium tungsten carbide grades (typically YG11C or YG15C depending on application) featuring a fine-to-medium grain structure. This configuration balances abrasive wear resistance with impact strength, helping prevent premature button shear or thermal fatigue under load.
Spherical buttons are suited for very hard, abrasive formations to minimize chipping. Ballistic buttons offer faster penetration rates in soft to medium-hard rock. Conical buttons are ideal for medium-hard formations where cutting speed and tool life must be balanced.
Yes, all our shank adapters—such as the Epiroc Cop 1032, Furukawa HD 709, and other model numbers—are designed to meet exact OEM specifications, ensuring reliable fitment and power transmission inside the power head.
We use high-grade structural alloy steels (like 23CrNi3Mo) and employ high-precision hot-pressing or brazing methods. This establishes a tight press-fit, preventing inserts from loosening even under heavy loads.
For standard catalog configurations, we maintain stock to support prompt shipment. Custom specifications or large volume orders generally require 30 to 45 days for forging, machining, heat-treatment, and final quality assurance.
