Two wings Φ27 Φ28 Φ32 Φ42(full piece and half piece
|
|
Characteristic:
|
This kind of new PDC has a high impact resistance, stand wear and tear, drill faster, capable of improving well boring with much greater efficiency, and at the same time, it has also much longer life.
|
|
Service application:
|
It is suitable for PDC drill-bits used in the rock stratum with hard quality.
|
|
Application:
|
Medium to hard rock, that is, the rate of drilling <10(f<10)
|
PDC diamond drill bit for anchoring drill machine is made by with premium PDC cutter, with high abrasion resistance, impact resistance and drilling efficiency. Their life is 10—30 times of alloy bits, usually the blade has 2 or 3 wings.
PDC anchor bits are mainly used in mining, coal picking, tunneling, water conservation and so on for soft and medium formation drilling, they work under low drilling pressure, medium-low speed, heavy drainage
