PDC drillbits

PDC drillbits;
Application: applying to the anchor-net work support hole drilling in coal mine, transportation, water and electricity, and so on.

Features:
   1. The wings are higher wear resistance and impact toughness;

  2. To repeat repair and grind are not necessary;

  3. Long life drill;

  4. Drilling efficiency could be promoted sharply in penetration of high –medium hard rock formation and labor intensity could be reduced.

  5. It is suitable for drilling in the rock formation from four to twelve.

 

Cemented carbide anchor-shank drill bit

Application:

Applying to the anchor-net work support medium coal and soft drill in coal mine, transportation, water, electricity and so on.

 

Features:

1.   Use high strength import alloy;

2.   High toughness and rigidity;

3.   Owning to the differences in cutting wings, it overcomes the weakness of PDC anchor-shank bits witch is easy to be pasted during its drilling in coal seam;

4.   Its drilling speed is faster twice to three times than PDC anchor-shank bits;

5.   It is suitable for drilling in the rock formation from one to six.

PDC non- core drill bits

Application:  Applying to the penetration of geological exploration hole, gas hole, water discharging hole and grouting hole under coal mine.

Features:

1.     The knife edge is sharp; more cutting free faces;

2.     High drilling efficiency.

3.     We can choose different labial structure in accordance with the features of rock.

4.     Owning to high utilization rate of pure drilling time and short auxiliary time, we can reduce labor intensity effectively and make good comprehensive benefits
