Product Overview
PDC Drill Bit With Extremely Fast Penetration Rates And Very Long Working Life
about PDC Drill Bit
Polycrystalline diamond compact (PDC) bits deliver premium performance and durability for a wide range of standard drilling applications. These matrix- and steel-bodied bits incorporate the latest cutter technology, computational fluid dynamics (CFD), enhanced hydraulics, and various structure geometries to maximize ROP.
Mainly used to drill the roof and side supporting hole, the gas drainage, water infusion, geological exploration hole and grouting hole and so on for the coal mine seam, water conservancy and hydro-power, dam and roadway construction of bolt-mesh support.
Product Description
Polycrystalline diamond compact (PDC) drill bits are made with synthetic diamond cutters in either steel
or matrix body material. PDC drill bits revolutionized the drilling industry with a wide application range
and high rate of penetration (ROP) potential. Unlike roller cones, these polycrystalline diamond compact
(PDC) drill bits are one piece bodies with no moving parts. The fixed-cutters shave away the rock, making
it possible to operate with higher rotation speeds more efficiently in consolidated formations.What Does Polycrystalline Diamond Compact Bit Mean?A polycrystalline diamond compact (PDC) bit is a bit that uses synthetic diamond disks, called "cutters." to
shear its way through rock with an ongoing scraping motion. The PDC bit is particularly suited to drilling
throuah shale formations. which present some specific problems with reaard to borehole instabillitv. such
as borehole narrowing.
Types of PDC Bits1. Matrix Body PDC Bits“Matrix” is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a softer, tougher, metallic binder. Matrix is desirable as a bit material, because its hardness is resistant to abrasion and erosion. lt is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loading. Matrix is relatively heterogeneous, because it is a composite material. Because the size and placement of the particles of tungsten carbide it contains vary (by both design and circumstances, its physical properties are slightly less predictable than steel. Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.2. Steel Body PDC BitsSteel is the opposite of matrix. It can of withstanding high impact loads, but is softer and lacks protective features. The strength and ductility of steel give steel-bit bodies high impact resistance. Steel bodies are considerably stronger than matrix bodies. A beneficia feature of steel bits is that they can easily be rebuilt a number of times because worn on damaged cutters can be replaced rather easilv. This is a particular advantaae for operators in low-cost drilling environments.

SPECIFICATIONS PDC driling drag bits
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.
Cutting Structure of this series PDC bit :
1. PDC cutter size 13mm*16mm and 13mm*10mm
2. PDC bit blades number is six
3. The crown part of PDC bit is a long parabolic crown
4. PDC cutter is double row in each blade
5. Each blade has teeth to protect the diameter of the PDC bit
6. The surface of each blade is designed with tungsten carbide welding to enhance the wear resistance of
the blade and improve the service life the PDC bit.
