High Hardness Water Well Drill Bits 3 Blades Steel Body Abrasion Resistance
Water Well Drill Bit introduction
PDC concave drill bits is made from high quality steel and PDC cutter. Combining wear-resistance of PDC cutter and toughness of carbon steel makes the drill bit has a long service life and high drilling speed.PDC concave bit is suitable for drilling soft to medium hard rock formation. They are often use with underground drilling rig.
Selection of differnt types PDC cutters:
| Sharp kind PDC insert | Are suitable for soft & medium rock.Sharp ones faster than flat ones in these rocks | Mudstone, shale, soft sand, peat, rock, mudstone, tuff,Hard marl, marl and other hard sandy clay, Limestone, marble, dolomite, rhyolite, limonite, etc |
|
Flat kind PDC insert | Are suitable for medium & hard rock.Flat ones more wear-resisting than sharp ones in hard rock. |
Limestone, marble, dolomite, rhyolite, limonite, Basalt, gneiss, granodiorite, hornfels, pegmatite, diabase,etc |
|
Spherical PDC insert | Drilling fast , good wear-resistance | Soft, medium hard rock are best choose. |
Details of PDC drill bit:
1. PDC bit is mainly used for drilling soft and medium formation, it work under low drilling pressure,midium-low speed,big drainage. PDC drill bits are mainly used for drilling soft and medium - hard formation,it’s the preferred choice in general non-coring drilling in soft and middle hard formation, such as mud stone, limestone, shale, sandstone and granite etc, very high cost -effective.But easy to wear when drilling abasive formations.
2. We can supply all kinds of PDC Coring and non-coring bits, PDC sintering matrix bits and PDC anchoring bits. PDC bit can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway.
3. We also can design PDC bits according to customer requirements, such as different geological condition, special strata and so on.
Production technology of water well bit
Before production, the bit body has been tested many times for the density and hardness, and so on. Pure silver solder for welding, in the case of ensuring that the internal structure of the diamond composite piece is not destroyed, the most solid welding, not to drop the piece, not broken teeth. The bit will be designed for inside and outside diameter keeping, so as to enhance the wear resistance of the bit and prolong the service life of the bit. For Different Rock strata, we can provide various diamond composite bits and special diamond composite bits to overcome special strata according
to the customer's requirements and geological conditions.
