Product features and application fields
Product features
Independent rotation design: The impact and drill bit structures are separate, allowing for individual adjustment of impact energy and drill rod speed, making it less likely to get stuck, suitable for medium-hard to hard rock (F=8-18), with a hole diameter of 65-89mm.
The structure is compact: the gear-type air motor is installed at the top of the rock drill to shorten the total length of the rock drill and lower its center height, making it more suitable for operations in narrow underground mining sites.
High-efficiency energy saving: The impact structure adopts valveless air distribution technology, with high utilization of compressed air, saving energy.
Reliable and durable: made of alloy steel, with a gear air motor driving the drill head system, and a two-stage helical gear reduction design to extend service life.
Application fields:
- Underground mining: drilling fan-shaped or ring-shaped blast holes (such as in metallurgical ore extraction)
- Open-pit engineering: operations for medium-depth holes such as anchor rod holes and slope protection holes.
- Special operating conditions: high stability drilling in fractured and karst formations.
Product details
Independent impact and rotation rock drill design: Utilizes a structure where impact and rotation are separate, allowing the impact force and drill rod speed to be adjusted independently based on the characteristics of the rock being drilled, effectively reducing drill jamming.
Forging and heat treatment: Forging and heat treatment techniques enhance the hardness and toughness of core components.
Structural optimization: The gear-type air motor is positioned at the top of the rock drill to reduce the overall length of the rock drill and lower its center height, making it more suitable for operations in the narrow mining areas underground.
why choose us?
High-performance rock drilling, suitable for complex geological conditions
Powerful impact: Utilizes valveless air distribution technology to optimize the utilization of compressed air, ensuring high-efficiency rock drilling even in F8-18 grade hard rock.
Independent rotation anti-sticking bit design: The torque of the rotating bit is large, and when encountering fractured or karst strata, it can quickly escape from difficult situations through weak impact and strong rotation, reducing downtime.
Adapt flexibly to various job scenarios
Suitable for both underground and open-pit mining: can be used for drilling upward fan-shaped or ring-shaped blast holes in underground mining sites, and can also be paired with open-pit rigs to complete horizontal or downward drilling (such as anchor bolt holes, slope protection projects)
Compact structure: exterior dimensions of 890×310×310, weighing only 100 kg, suitable for narrow alleys, and seamlessly compatible with FJY27 or FJY27A type disc drilling frames.
Reliability and low maintenance costs
Durable material: The alloy steel body is paired with a gear air motor drive, featuring a two-stage speed reduction design to extend its lifespan.
User reviews: Leading annual sales, low failure rate according to customer feedback, especially suitable for long-term high-intensity operations.

1.The length of the drill tail is unqualified. 2. The piston end face has excessive indentation. |
1. Replace with a qualified drill tail. |
Q: What precautions should be taken when using YGZ100 Drifter Drill?
A: For different rock types, the impact energy, drill bit speed, and axial thrust of the rock drill must be adjusted according to the dust removal situation to achieve better drilling results.
When encountering rock layers with numerous fissures and well-developed caves, the impact energy should be reduced, the rotation speed of the drill bit increased, and if necessary, the impact can be stopped entirely, relying solely on rotation to pass through the stuck drill section, thereby eliminating the stuck drill problem.
The operating pressure should not be less than 0.5 MPa, and it is recommended that the flushing water pressure be 0.5 MPa lower than the operating pressure.
To ensure normal lubrication during machine operation, lubricating oils and greases should be selected reasonably based on the working environmental temperature. The table below introduces several lubricants for reference：

The pipeline connected to the rock drill must be equipped with an oil injector with a capacity of more than (or equal to) 5 liters, which can adjust the oil supply. Before operation, check the oil amount and replenish sufficient lubricating oil in time. The method to check the oil supply is: place your hand at the exhaust port of the machine, if there are uniform and fine oil droplets sticking to your hand in the exhaust, it indicates that the lubrication is normal and the oil amount is appropriate.
The drill string used should meet quality requirements.
When drilling, the drill rod and drill tail, as well as the connection ends of the drill rods, must be tightly joined to ensure the efficiency of energy transmission and the service life of the drill rods.
Q: How to maintain YGZ100 Drifter Drill?
A: 1,A rock drill that is in normal operation must undergo regular inspections and maintenance, timely replacement of failed parts, and ensure the reliability of its operation.
2,During maintenance, apply the specified lubricant to the gears and bearings.
Apart from regular maintenance, each shift should check if all fasteners are loose and secure before use. After a trial run to ensure everything is functioning normally, work can commence. If any abnormalities are detected, operations should be stopped immediately for inspection. Before ending the task, water should be closed first, and the machine should be run lightly for a short period to drain any remaining water inside, preventing rust on the internal parts.
For long-term storage or maintenance of machinery, disassemble and clean the components before storage, apply anti-rust oil, and then reassemble. The equipment must be stored in a dry place.
