Alloy Steel Drilling Rig Tools , Rotary Drilling Rig Components Long Service Life
The impregnated diamond bits are typically used in the drilling of hard earth layers (hard stratum or formations), and it is quite suitable for breaking and non-breaking of 5-10-level stratum and a variety of abrasive formations.
Core Bits are used for drilling materials like the rock, concrete, limestone, granite, marble, clay, basalt, schist, quartz etc.
The bit mainly consists of diamond, steel body, carbide powder and polycrystalline diamond.
To select the right bit for the job, assess the speed and power of your drill for the size and depths of the holes to be drilled and assess ground conditions such as rock type/formation and down-hole conditions.
