View Impactors PricelistThe global mining and excavation landscape is undergoing a massive transformation driven by deeper ore extraction, increasingly abrasive rock formations (ranging from 150 to over 300 MPa unconfined compressive strength), and tight cost-per-meter operating constraints. In top hammer drilling, down-the-hole (DTH) impacts, and rotary blast hole operations, the wear performance of consumables determines site profitability.
Standard commercial drill bits suffer catastrophic insert shear or rapid gauge wear when drilling ultra-hard strata like quartzite, iron ore, and basalt. High-performance rock tools leverage vacuum-sintered YK05 / YK08 grade Tungsten Carbide (WC-Co) button inserts integrated into alloy steel bodies (such as 23CrNi3Mo or 42CrMo4) subjected to precision carburizing and multi-stage shot peening.
Tungsten carbide buttons serve as the primary interface transferring kinetic energy from pneumatic or hydraulic rock drills into the rock matrix. Modern manufacturing utilizes coarse-grained Cobalt matrix structures (6% to 10% Co content by weight) to strike an optimal balance between fracture toughness ($K_{IC} \ge 14.5 \text{ MPa}\cdot\text{m}^{1/2}$) and abrasive wear resistance (Rockwell Hardness 88.5–90.5 HRA).
The structural body of a drill bit or shank adapter must withstand high-frequency tensile and compressive shockwaves. Shandong KAT Drilling Tools utilizes continuous atmosphere-controlled gas carburizing furnaces to generate a deep, controlled surface case hardness (HRC 58-62) while maintaining a resilient, shock-absorbing core (HRC 38-42). This prevents micro-cracking and thread galling under extreme torque.
| Material Component | Alloy Grade | Heat Treatment Process | Tensile Strength (MPa) | Core Toughness (J) |
|---|---|---|---|---|
| Threaded Button Bits | 23CrNi3Mo / 40CrNiMoA | Gas Carburizing & Vacuum Quench | ≥ 1,470 | ≥ 78 |
| Shank Adapters / Striking Bars | 35CrMo / 42CrMo4 High-Alloy | Induction Hardening & Deep Tempering | ≥ 1,580 | ≥ 85 |
| DTH Impactor Cylinders | 20CrNi2Mo Precision Tube | Liquid Nitriding & Shot Peening | ≥ 1,250 | ≥ 90 |
| Tapered Drill Rods | 55SiMnMo Spring Steel | Full-Length Carburization & Anti-Corrosion Oil | ≥ 1,350 | ≥ 70 |
The centralization of tungsten raw material refining, raw steel mills, and automated 5-axis CNC machining centers in Shandong, China has created a world-class manufacturing cluster. Shandong KAT Drilling Tools leverages 40+ years of industrial heritage to deliver tier-1 OEM specification tools at a fraction of Western brand costs, drastically reducing total cost of ownership (TCO).

Inquire NowIn underground gold, copper, and nickel extraction, space constraints necessitate high-speed hydraulic drifters operating at power ratings between 18 kW and 35 kW. Top hammer thread systems like R32, T38, and T51 must endure percussive frequencies of 50 Hz to 70 Hz. Shandong KAT’s YK05 button bits and Hex25 drifter rods maintain structural integrity against hole deviation, ensuring precise blast hole alignment and reduced overbreak.
Surface quarries require large-hole productivity to maximize blast efficiency. DTH impactors such as the Mission40 and DHD360 paired with 102mm–165mm button bits operating under high wind pressure (1.8–2.5 MPa) provide rapid penetration through granite, limestone, and iron ore. High air volume flushing prevents re-crushing of rock cuttings, extending bit life by up to 25%.
The mining sector is actively transitioning toward zero-carbon site operations and autonomous drilling fleets. Key advancements defining next-generation consumables include:
YK05 is a premium grade cemented carbide engineered specifically for rock percussive drilling. It combines a refined grain size with an optimized cobalt binder matrix that increases bending strength by over 15% compared to standard grades. This significantly minimizes micro-fracturing and button popping when hitting unpredictable quartz veins or high-stress rock strata.
Shank adapter failures typically result from excessive fatigue stress, thread galling, or improper alignment with the drifter piston. Shandong KAT uses forged 35CrMo / 42CrMo4 high-alloy steel treated with specialized induction hardening and deep carburization. This ensures a surface hardness of HRC 58-62 while retaining a tough core that absorbs percussive shockwaves without cracking.
Top Hammer drilling transfers percussive energy from the drifter machine through the drill steel to the bit. It is highly efficient for smaller hole diameters (32mm to 127mm) up to 20 meters deep. DTH drilling places the impactor directly behind the bit down in the hole, eliminating impact energy loss over depth. DTH is ideal for larger hole diameters (100mm to 300mm+) and deep blast holes or water wells.
