PDC drill bits
PDC drill bits are mainly used for drilling soft and medium hard formation. Such as mud stone, limestone, shale, sandstone and granite etc.
PDC drill bits used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy and hydropower, road construction, bridge and building.
Operating condition :
PDC drill bits work under low drilling pressure, midium-low drive speed ,big drainage .
50mm, 56mm, 60mm, 65mm, 75mm, 94mm, 98mm, 113mm, 120mm, 120.5mm, 124mm, 143mm, 149mm, 152mm, 173mm, 190.5mm, 203mm, 254mm
Wireline core bit : A gauge, B guage, N gauge, H gauge , P gauge.
Aftersales service :
If any of the following occur , we will responsible for replace . And we will afford the shipping cost of replace.
1.Thread can not fit customers' rod or barrels.
2.Matrix or PDC cutters falling not caused by drilling.
3. Size, Cutters , or other technical parameters are different from the requirement of customers.
4. working life obviously short caused by manufacture.
Our Advantage :
1. We choose the best PDC cutters with excellent wearability and impact toughness, make the working life of our PDC drill bits are much longer than the other’s,
2. We built our own factory of drill bits. All our goods pass through our rigid quality control before shipment .
3. We have rich experience in the field of large engineering projects such as dam construction, road and railway construction , We have our own construction team.
