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.
Frequently Asked Questions
Q1: Is the Y26 compatible with European standard spare parts?
A: Y26 follows the classic industrial standard. While unique in design, our parts are fully compatible with most standard Y26 models globally.
Q2: Why is water leaking from the exhaust port?
A: This indicates a damaged internal water tube or O-ring. We recommend immediate replacement to protect cylinder lubrication.
Q3: Why choose Y26 over Y24 for heavy-duty demolition?
A: The 26kg weight provides more stable vertical thrust, while the ≥30J energy ensures faster penetration in hard concrete and demolition sites.
