Product Description
The down-the-hole drilling rig uses the impactor and the drill bit that dive into the bottom of the hole to impact and break the rock, so it is called a down-the-hole drilling rig. Widely used in metal mines, hydropower, transportation, building materials, harbors and national defense projects. Down-the-hole drilling rigs can drill holes in rocks above medium hardness (f≥8).
The down-the-hole drilling rig can be used for drilling rock anchor holes, bolt holes, blast holes, grouting holes, etc. in urban construction, railway, highway, river, hydropower and other projects.

The down-the-hole drilling rig is suitable for various types of drill bits suitable for various projects to choose from!

1. The down-the-hole drilling rig uses the motor as the rotary power through the high-performance reducer; the cylinder is used as the propulsion power. The hydraulic system is omitted, so the mechanical efficiency is high, the cost is low, and the performance is stable.
2. With anti-jamming protection, when the drilling tool is stuck, the motor is not easy to be burned, and the reducer is not easy to be damaged.
3. It is light and easy to move. The weight of the whole down-the-hole drilling rig is less than 500Kg, and it can be broken down into three pieces, which is convenient for moving and putting on shelves.
4. The rolling carriage is adopted, and the track is not easy to wear.
5. The down-the-hole drilling rig adopts semi-automatic dismantling of drill pipes, which has high working efficiency.

1. It is designed for drilling 90-127mm.
2. Diesel powered down-the-hole (DTH) rigs have excellent maneuverability, smaller footprint and the ability to serve multiple locations.
3. HW-916 is a trusted machine for mining and construction companies and contractors engaged in presplitting and conventional production blasthole drilling.

The down-the-hole drilling rig can be used for drilling rock anchor holes, bolt holes, blast holes, grouting holes, etc. in urban construction, railway, highway, river, hydropower and other projects.
