Product Description

Hot Sale 3 Wing PDC Concave Drill Bit for Water Well Drilling 

PDC Drill Bit Introduction

1. About the PDC drill bit 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 choice for hard formation.
2. About our PDC drill bit side water hole,there are three water holes,and they can cool the pdc cutter and wash out the head mudstone.
3.About our PDC drill bit two pillars, the material is 1308/1304 pdc cutter and cemented carbide,and there are two middle water holes. Its function is cooling pdc cutter, blowing the mudstone and damage to the compact(pdc cutter).
4.About our pdc cutter, the material is 13x08/13x04mm PDC with diamond and tungsten carbide,so it applys for hard rock.

Shape of PDC Insert	Features	Applied Rock Formation
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.

Main Features

1.Suitable for soft, medium and hard formations
2.Super strong material promotes gauge wear resistance to provide long bit life
3.The cutter's back rake has been unique design, reducing the bit torque and increasing aggressiveness
4.Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow.

-PRODUCT BRIEF -

Product Introduction:
PDC non coring drill bit is mainly used for water injection and drainage in coal mine geology, rotary drilling for underground gas drainage in coal mine and drilling for anchor net support in coal mine. Its service life is 10 to 30 times longer than that of a normal carbide drill. Different structure of the drill body welding different positions of the composite pieces, so that the functional properties of the bit is also different.So there are many different types of PDC non coring drill bits on the market.
PDC non coring drill bit is highly adaptable to drilling in complex rock formations, with good stability and hardness, strong wear resistance, blade strength and impact resistance, high drilling efficiency. The PDC non coring drill bit is a super-hard geological diamond that can be directly connected to the drill pipe. Speedmade Industries Co., Ltd. 's PDC non coring drill bit not only has the above advantages, but also has high Drilling verticality.
1. General specification:75#,90#,113#,133#,153#,171#,219#
2. Enhanced specification:75#,90#,113#,133#,153#,171#(Dual water ball),171#(Three water ball)
3. Special type specification:65#,153#(4 wing),3 wing(It can be directly connected with the drill pipe)Specifications are 32#,42#,50#,60#,76#,89#(Routine for 50#)
4. Composite sheet reinforced:There are mainly 1304,1308,1313,1613,1906,1908,Routine for1304,Enhanced1308 Specifications are75#,91#,110#,130#,150#,170#.

In general, conventional 1304 is the most common, and the dosage is also the largest. According to the formation conditions, it can be matched with the geological sheet/petroleum sheet to achieve reasonable use.
Applicable stratum: clay stratum, sand stratum, gravel stratum and weathered stratum.
