Exploration Mining Diamond Tip Core Drill Bits for Concrete 122 mm
Description:
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.
It mainly consists of diamond, steel body, carbide powder and polycrystalline diamond. The polycrystalline diamond is utilized to avoid too much abrasion of drill bits. The impregnated diamond is synthetic diamond (also called artificial diamond), which costs less but is more suitable to be used in drilling hard formations.
As to the packing, it is first packaged by cartons, and then put into the plywood case.
Specifications:1. available in all standard drilling sizes (A,B,N,P,H).
2. various waterways design.
3. long bit life and good performance.
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.
Non-standard also can be made as your requirement.
