Y26 Hand Held Rock Drill: Heavy-Duty Wet Drilling Solution for Quarry & Demolition
What makes the Y26 different? The Y26 Hand Held Rock Drill is a heavier (26 kg), more powerful pneumatic jackhammer specifically optimized for Wet Drilling (Water-flushing). It is the preferred choice for drilling blastholes in medium-hard and hard rock (f=8-18) where silica dust suppression is strictly required for environmental demolition and mining.
🌍 Industrial Grade Performance: Delivering an impressive impact energy of ≥ 30 J, the Y26 offers robust performance comparable to premium heavy-duty hand-held drills, but with extreme cost-effectiveness.

⚡ Air & Water Requirements for Y26
Air Consumption: ≤ 47 L/s (≈ 100 CFM) @ 0.4 MPa.
Required Water Pressure: 0.2–0.3 MPa.
Recommended Water Flow: 4–8 L/min (depends on hole depth & bit size).
Note: Constant water pressure and flow are required to flush out rock cuttings and cool the bit during heavy demolition.
Key Features & Applications
✔️ Dust Suppression: Eliminates hazardous silica rock dust, meeting strict demolition site environmental standards.
✔️ High Impact Penetration: Generates ≥ 30 Joules of impact force, penetrating hard rock faster than standard 24kg drills.
✔️ Typical Rock Types: Highly effective in granite, basalt, hard limestone, and marble formations.
✔️ Typical Jobs: Ideal for bench drilling, plug & feather hole drilling, small blast hole drilling, and concrete demolition.

Y26 Spare Parts & Accessories
| Core Spare Part | Function / Role |
|---|---|
| 1. Piston (Y26) | Main impact component, providing strong ≥30J energy. |
| 2. Coaxial Water Tube | Crucial for wet drilling and dust flushing at demolition sites. |
| 3. Rifle Bar & Nut | Controls the rotation mechanism for the bit. |
| 4. Pawl / Ratchet | Ensures stable unidirectional rotation. |
| 5. Pawl Spring Set | Maintains tension for the ratchet mechanism. |
| 6. Valve Chest | The core of air flow distribution. |
| 7. Front Head | Secures the drill rod safely. |
| 8. Shank Bushing | Protects the 22x108mm hex shank contact area. |
| 9. Handle & Throttle | Ergonomic operator control trigger system. |
| 10. Muffler Assembly | Reduces exhaust noise to protect operators. |
| 11. Connector | Provides air and water hose connections. |
| 12. O-Ring & Seal Kit | Consumables that prevent air and water leakage. |
Safety Guidelines
1. Pre-Drilling: Check integrity of all parts and hose connections. Use a line oiler to prevent cylinder wear.
2. Wet Drilling Only: Turn on water before air. When stopping, turn off air before water. Avoid dry drilling.
3. Correct Posture: Let the 26kg weight do the work; do not use body weight to force the drill.
Heavy-Duty Y26 Pneumatic Rock Drill & Demolition FAQ
Q: Is the Y26 compatible with European standard spare parts?
A: The Y26 is built on the classic industrial standard. While different from European designs, our Y26 parts are fully compatible with most standard Y26 models globally.
Q: What causes water to leak from the exhaust port?
A: This usually indicates a damaged internal water tube or O-ring seals. Check the central water tube and replace the O-ring seal immediately to prevent water from entering the cylinder.
Q: Why is Y26 better than Y24 for heavy-duty demolition?
A: The Y26 weighs 26kg and delivers higher impact energy (≥30J), providing better downward stability and faster penetration for concrete demolition and hard granite quarrying.
Q: What is the average drilling speed of the Y26 in hard granite?
A: In hard granite (f=8-12), the Y26 achieves a drilling speed of approximately 250mm to 350mm per minute depending on the air pressure (0.5MPa recommended) and bit sharpness.
Q: What size air compressor is required to run a Y26 rock drill?
A: You need an air compressor with a minimum capacity of 3.5 m³/min (125 CFM) to ensure stable 0.5 MPa pressure for one drill. For optimal performance in deep-hole quarrying, a 4 m³/min compressor is recommended.
Q: Can the Y26 be used for dry drilling instead of wet?
A: The Y26 is optimized for wet drilling to suppress silica dust and cool the drill bit. If dry drilling is necessary, ensure you have a high-capacity air flushing system, though we strongly recommend our Y24 model specifically for dry applications.
Q: How often should I lubricate the pneumatic rock drill during shifts?
A: Continuous lubrication is critical. You must use a line oiler (FY200B) filled with specialized rock drill oil. Check the oil level every 2-3 hours of operation to prevent the piston from seizing due to high impact heat.
Q: Do you supply Y26 pistons and rifle nuts for international projects?
A: Yes. We maintain a full stock of Y26 spare parts, including pistons, rifle bars, pawls, and valve chests. We offer fast express shipping to mining hubs in India, the Middle East, and Africa.
Q: What is the maximum borehole diameter for the Y26 jackhammer?
A: The Y26 is most efficient for borehole diameters between 34mm and 42mm. For quarrying, we recommend using tapered button bits with 7° or 11° tapers for the best penetration rates in hard rock.
