KAT DRILLING
Explore our primary catalog of high-penetration rock drill bits, self-drilling anchor systems, and extension rods manufactured for extreme geological conditions.
The global extraction sector is undergoing a profound paradigm shift driven by deep-level underground excavation, demand for critical transition minerals (copper, lithium, nickel, and cobalt), and rigorous decarbonization targets. In modern rock drilling operations, consumables such as tophammer button bits, down-the-hole (DTH) hammers, extension rods, and self-drilling anchor systems represent more than just operational expenditures; they directly dictate Rate of Penetration (ROP), energy consumption per meter drilled, and overall drill rig uptime.
Procurement teams and mine operations directors no longer evaluate rock tools solely on initial purchase price. The industry key performance metric has shifted decisively toward Total Cost Per Drilled Meter (CPM). Selecting premium-grade carbide inserts and stress-relieved steel alloys reduces frequency of rod changes, minimizes stuck tool hazards, and dramatically lowers carbon intensity per metric ton of fragmented ore body.
Combining four decades of metallurgical mastery with automated CNC manufacturing to deliver world-class drilling consumables.
We have more than 40 years of specialized drilling tool manufacturing experience. All this accumulated engineering expertise is built directly into our rock drilling tools—delivering maximum operational safety and longevity to your site.
We target outstanding mechanical performance in all our tools and accessories. Ultimately, that means excellent hole straightness, optimized air/hydraulic flushing, and minimal cost-per-meter drilling for your project.
As one of the foremost professional rock drilling tool manufacturers in China, Shandong KAT Drilling Tools maintains rigorous ISO quality controls, state-of-the-art heat treatment lines, and premium tungsten carbide selection.
We engineer and manufacture over 500 product types across Top-hammer equipment and DTH impactors for every application: underground mining, tunneling, surface open-pit mining, water well drilling, quarrying, and civil engineering.
Rock conditions vary significantly—from soft, abrasive sandstone to ultra-hard granite with Unconfined Compressive Strength (UCS) exceeding 250 MPa. Shandong KAT provides custom-tailored string configurations optimized for specific drilling dynamics.

At Shandong KAT, manufacturing rock drilling consumables requires strict control over heat treatment and micro-structure alignment. Our button bits utilize YK05 micro-grain tungsten carbide inserts, providing superior resistance against abrasive wear and micro-chipping under high-frequency percussion.
Drill steel bodies are forged from high-tensile chrome-molybdenum alloy steel. Through controlled carburization and shot-peening processes, we induce compressive surface stress that effectively prevents thread fatigue and stress corrosion cracking.
We understand that drill rig downtime costs thousands of dollars per hour. Shandong KAT maintains robust international logistics frameworks, offering expedited air freight, full-container-load (FCL) sea shipping, and localized regional warehousing options.
Our operations comply with global quality and environmental standards:
