ETS82 High-Speed Air-Leg Rock Drill (Tunneling & Mining Beast)
Why upgrade to the ETS82? The ETS82 Air-Leg Rock Drill is a new generation of high-speed pneumatic drilling machinery. Engineered specifically for railway, highway, and underground mine tunnel excavation, it is designed for one primary goal: Extreme Penetration Speed in medium-hard to hard rock (f=8-18).
🌍 The Next Generation Standard: Delivering a massive impact energy of ≥ 78 Joules, the ETS82 drills significantly faster than legacy models. Among air-leg drills of its class, it stands out for its optimized valve system, high efficiency, and deep hole drilling capability. It operates seamlessly with the FT160A pusher leg.

⚡ Compressor & Setup Requirements
Air Consumption: ≤ 88 L/s (approx. 186 CFM) @ 0.5 MPa
Recommended Compressor: Minimum 200–250 CFM per drill to unleash its massive 78J impact power.
Required Air-Leg: Must be paired with the FT160A telescopic air-leg for horizontal and inclined tunnel drilling.
Note: The ETS82 consumes more air than standard drills, but converts it into unparalleled drilling speed, dramatically increasing tunnel advance rates.

Operation & Safety Guidelines
1. Pre-Check: Ensure air/water lines are clear, the FY250 oiler is filled, and connections are firm before starting.
2. Roof Safety: Always check for and scale down loose rocks on the tunnel roof near the working face.
3. Wet Drilling Only: Strictly forbid dry drilling underground. Turn on water first, then air. Turn off air first, then water.
4. Starting: Run at low speed (partial throttle) to open the hole collar, then switch to full speed.
5. Posture: Maintain a safe standing posture beside the drill. Never apply your body weight; let the FT160A air-leg provide the thrust.
Frequently Asked Questions (FAQ) & Troubleshooting
Q: Can I use the ETS82 as a hand-held drill without the air-leg?
A: No. The ETS82 weighs 26.5kg and generates massive 78J recoil. It is specifically designed to be mounted on the FT160A pusher leg for horizontal or inclined tunnel drilling.
Troubleshooting: The drill penetrates slowly despite high air pressure.
A: If the compressor is delivering sufficient volume (≥ 200 CFM) but penetration is slow, check the pusher leg thrust. If the air-leg isn't pushing hard enough against the rock face, the impact energy is wasted. Also, check if the button bit is dull and needs grinding.
