YO18 Pneumatic Rock Drill Lightweight 18kg Handheld Rock Drill High Frequency Impacts Corrosion Resistant Alloys
The YO18 Pneumatic Rock Drill is a highly efficient , 18kg lightweight drilling equipment engineered for professional excavation. This compact 550mm jackhammer excels in boring blast holes across small scale mines , construction sites , and stone quarries. With a standard H22x108mm shank size , it delivers high frequency impacts required to penetrate medium to ultra hard rock formations.
When paired with the FT - 100 Air Leg attachment , the YO18 transitions seamlessly into a versatile multi angle drilling rig, enabling operators to drill vertical , horizontal, or inclined blast holes with absolute precision.

Performance Advantages
- Advanced Flanged Control Valve : Optimizes internal airflow, ensuring instant startup, faster penetration rates, and reduced air consumption.
- Ergonomic Vibration Damping : Integrated heavy duty rubber shock absorbing handles significantly mitigate operational fatigue and protect workers from Hand Arm Vibration Syndrome (HAVS).
- High Economic ROI : Manufactured with premium wear resistant alloys, guaranteeing long component lifespans, minimal failure rates, and low maintenance costs.
Primary Industrial Applications
- Mining Industry : Ideal for small scale coal mines, gold mining, and limestone extraction.
- Infrastructure Projects : Widely utilized in mountain road construction, highway building, and water conservancy capital projects.
- Secondary Blasting : Perfect for boulder breaking, clearing rocky lands, and foundational excavation in larger open pit mines.
Operation Guidelines
Pre Operation Preparation
- Initial Cleaning : Factory applied anti rust oil must be thoroughly flushed before the first use. Disassemble, clean, and relubricate all mating surfaces.
- Line Purging : Always blow out debris from air and water hoses before connecting them to prevent internal cylinder contamination.
- Pressure Balancing : Maintain the flushing water pressure at 0.1 to 0.15 MPa lower than the working air pressure to prevent water backflow into the motor.
Safety Lubrication Guidelines
- Constant Lubrication : Fill the line oiler before starting. Running the drill dry is strictly prohibited and will void the component warranty.
- Oiler Inspection : Check the oiler housing frequently. Replace immediately if any structural cracks appear. Refill the oil reservoir every hour during continuous shifts.
- Explosion Prevention : In underground environments with combustible gas hazards, never use low flashpoint lubricants. Avoid idling the machine to eliminate friction spark risks.
Operator Safety Storage
- PPE Requirements : Pneumatic drilling generates high noise, vibration, and dust. Operators must wear certified hearing protection, anti vibration gloves, and dust masks.
- Pinch Breakage Alert : Stay alert to sudden drill rod breakages. Avoid positioning body parts between the rock face, the drill body, and the pneumatic air leg.
- Shutdown Routine: Always shut off the water supply first, letting the machine run dry for 30 seconds to purge remaining moisture and prevent internal rust.
- Long-term Storage : For extended storage, dismantle the unit, wash all components, apply a thick layer of protective oil, and store in a dry, temperature controlled environment.
