ROCK DRILL TYPES & MODELS
Choose the right rock drill for your project based on power source, drilling requirements, and working conditions. Explore our range of rock drills designed for mining, quarrying, construction, and rock excavation.
Gasoline Rock Drills
Powered by gasoline engines, these rock drills offer excellent mobility and independence from external power sources. They suit for remote locations, outdoor construction, quarrying, and field operations where portability and flexibility are essential.
Hydraulic Rock Drills
Designed for demanding drilling operations, hydraulic rock drills deliver high impact energy, efficient rock penetration, and reliable performance. Ideal for large-scale mining, quarrying, and tunneling projects that require high productivity and consistent drilling results.
Pneumatic Rock Drills
Using compressed air to generate powerful percussive action, pneumatic rock drills provide robust performance and dependable operation in tough working environments. Commonly used in underground mining, quarrying, and construction, they are valued for their durability and straightforward maintenance.
Electric Rock Drills
Electric rock drills provide stable power delivery and convenient operation for drilling tasks where a reliable electricity supply is available. They are suitable for construction, quarrying, and selected mining applications, offering efficient performance with no direct exhaust emissions at the point of use.
Handheld Rock Drills
Compact and easy to maneuver, handheld rock drills are designed for small-scale drilling, confined spaces, and jobs that require precise positioning. Their portable design makes them a practical choice for maintenance, secondary breaking, small quarries, and general rock drilling work.
Pneumatic rock drills, hand-held rock drills, gasoline rock drills, electric rock drills, and upward (stoper) drills — compare the core models below.

ROCK DRILLS APPLICATIONS & WORKING CONDITIONS
Drifting, stoping and blast-hole drilling in confined headings with leg-supported pneumatic drills.
Bench drilling, boulder breaking and dimension-stone splitting on surface sites.
Road, rail and hydropower tunnel faces, plus slope and foundation works.
Consistent, straight blast holes for controlled fragmentation and lower explosive cost.
RECOMMENDED SOLUTIONS BY ROCK TYPE
f 12–18
Granite, quartzite, basalt. Choose higher-frequency leg drills (YT28 / YSP45) with carbide button bits.

FREQUENTLY ASKED QUESTIONS
How do I choose the right rock drill?
Start from rock hardness, required hole diameter and depth, drilling direction, and available power (compressed air or not). Send these to our engineers for a model recommendation.
Which rock drill is suitable for my rock type?
For hard rock (f 12–18) we generally recommend high-frequency leg drills; for medium-hard rock, lighter models offer better efficiency. Final selection depends on your site conditions.
What are the required air pressure or power specifications?
Pneumatic models typically operate at 0.4–0.63 MPa with a matching compressor capacity. Gasoline models need no air supply. Exact figures are confirmed per model datasheet.
Which drill bits and spare parts are compatible?
Most models use H22 × 108 mm shanks with chisel, cross or button bits Ø34–45 mm. We supply matching rods, bits and wear parts.
What is the expected service life?
Service life varies with rock abrasiveness, maintenance and lubrication. We provide guidance per model once verified for your application.
What are the delivery time and warranty terms?
Delivery time and warranty depend on model, quantity and destination. They are confirmed in your project-specific quotation.
