MRING-XD integral multi-use symmetric caisng drilling ringbit is designed to case a hole simultaneously through unstable ground conditions. It is the economical pneumatic ring bit system.
MRING-XD integral multi-use symmetric caisng drilling ringbit are made up of:
1. A pilot bits with large internal flushing holes and external flushing grooves
2. Symmetrical ring bit (reamer) with internal bayonet coupling
3. Casing shoe for driving of casing.
The Pilot bits is attached to any common DTH hammer shank.

FAQ:
1. What is Symmetrix drilling?
Previously known in our industry as Concentrix, the updated Symmetrix system allows for the simultaneous casing and drilling of a hole. The system consists of three main components: pilot bit, ring bit (reamer) and casing shoe
2. What is drill casing in mining?
In underground mining, steel casing or steel pipe is used to line holes that have been bored or drilled for rising mains water, utility lines and paste fill, protecting the contents from damage and loss into open voids or broken ground.
3. Why is overburden important?
In a petroleum system, the overburden rock overlies the source rock and contributes to its thermal maturation because of higher temperatures at greater depths. The age and thickness of the overburden rock determines the burial rate and thereby influences the heating rat.
4. Where does overburden go during a mining operation?
Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant.
