High Performance Water Well Drill Bits / 3 Wings Drill Bit Constructio
High quality polycrystalline diamond compact (PDC) cutters as the cutting teeth, the bits have stable quality, high drilling efficiency, long service life.You can select different types of PDC bits according to the characteristics of formations,and improve the overall drilling efficiency.PDC drilling drag bit is made by PDC cutters and steel. It is one of the steel body PDC bit and belong to non core diamond pdc bit. Having the feature of long service life and wear resistance. Widely used in coal mining and water well drilling.
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 three wings drill bits
1.This is diamond drill bit for metal gauge,the material is cemented carbide,it is high hardness, wear resistance ,and good toughness.Under the 500 degree remain the same,also under 1000 degrees as the very high hardness .so it is good choose for hard formation,you can reduce your cost .
2.This is diamond drill bit for metal side water hole,there are three water holes,they can cool the pdc cutter and washout the head mudstone.To reduce off the field.
3.This is three wings drill bits two pillar,and the material is 1308 pdc cutter and cemented carbide,and there are two middle water hole,its function is cool pdc cutter and blow the mudstone.Prevent damage to the compact(pdc cutter).
4.This is three wings drill bits pdc cutter.Material is diamond and tungsten carbide,so it is apply for hard rock ,1308 pdc cutter the mainly feature is high durability.
