Product Description

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 Bits

1. 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 Bits

Steel 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 beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn on damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.
