PDC CUTTER

PDC Cutter is a kind of composite material composed of diamond and hard alloy matrix, pdc cutter with high hardness and good wear resistance.

Pdc cutter suitable for soft to medium hard geological drilling, the impact toughness and high thermal stability, heat resistance temperature can reach 750 ℃ (two minutes), these pdc cutter have plane and various groove surface type, we can according to user needs and design type slot, grinding, polishing and chamfering.

Here are our different series of PDC Cutter.

A, W series PDC cutter

PDC Cutter in drilling and rock work face top surface of tooth structure become a work site, the structure of the tooth surface line row "teeth" become a blade, cutting rock power and efficiency is better than no tooth of planar drill PDC tooth,PDC Cutter tooth type outside using drill tooth bit, PDC can improve drilling teeth rock fragmentation efficiency obviously.

Especially for the prone skid formation, it can reflect the advantages of its special external structure.

The cross section shape of the external PDC drill teeth can be triangular, trapezoid, square, circular or wavy.

The tooth height and the arrangement density can be designed respectively according to different drilling requirements.

B, L series PDC cutter for oil drilling

The working mechanism of "scraping" to "plough cutting" can be realized by changing the diamond end surface of the diamond composite drill teeth from plane to surface. This structure is conducive to the rapid arrangement of rock debris, reducing the resistance of the drill teeth, significantly improving the rock-breaking efficiency of the diamond composite drill teeth and greatly improving the drilling speed of the bit.

The overall impact resistance of the drill teeth is greatly improved due to the arched structure.

C, U series PDC cutter for oil drilling

PDC cutter for oil drilling with u-series combination tooth interface,the interface between the diamond layer of u-series PDC and cemented carbide matrix is composed of a central region shell groove plus an external ring structure of inclined cone surface. This structure not only enhances the binding force by using local convex and concave, but also improves the capacity of drill teeth to withstand cutting force and improves the impact resistance in the macroscopic shape design.

In 2009, the utility model patent was obtained (patent number: ZL200920260048.0).

U series products have been tested in the market for nearly ten years, with a total of more than 8 million pieces put on the market.

Excellent in quality and stability, it was once HMR's brightest star.

The U series is still popular today, which is directly related to the adoption of decobalt technology in recent years.

The application in non - special strata has been evaluated and praised.

D,S series PDC Cutter for oil drilling

S series PDC Cutter for oil drilling USES full-flow linear teeth diamond composite,the outer ring of the interface between diamond layer and cemented carbide substrate of S series PDC adopts the design of wave surface oblique cone, and the central region is a wave concentric circle.

Streamline design is a consistent characteristic of HMR.

This design is unique to HMR (patent no. : ZL201020253652.3). The streamline design reduces the residual stress after high pressure sintering and increases the joint area between the two layers.

S series adopts the technical scheme of imported raw materials plus new ultra-high pressure sintering technology to highlight the high abrasion resistance and impact resistance of materials.

In the past five years of the application of S series products, the company has demonstrated excellent comprehensive performance, and some loyal customers still insist on appreciating the advantages of S series products.

E,M series linear tooth - shaped interface diamond PDC cutter for oil drilling

The interface between the diamond layer and cemented carbide matrix of m-series PDC is composed of unidirectional straight-line wavy tooth structure. The wave shape of the tooth, the height and spacing of the tooth will affect the strength and residual stress of the interface. Sinusoidal wave form is recommended as the best.

The world's first application of non-planar interface technology in PDC cutter tooth shape, has a history of 20 or 30 years.

Due to its simplicity, reliability, economy and practicality, the tooth shape is still very important in small size (4-11mm in diameter) PDC cutter and some occasions requiring high reliability or cost performance.

F,ZU series - PDC cutter for oil bore and shallow drilling

The ZU series is PDC cutting teeth, which are used for the production process of oil drilling composite sheet and high-quality raw materials for the oil calibers and shallow drilling development. It is suitable for the industries such as oil calibers, coal field exploitation and geological exploration, and has the characteristics of economic durability.

Diamond end surface can provide two options: plane and arc surface.

The interface between diamond layer and cemented carbides adopts the original UG series combined tooth form, which is composed of the central region with the external ring structure of turtle back groove and oblique cone surface. The structure is stable and reliable, and the PDC has excellent impact resistance and wear resistance.

This series of products can effectively reduce the wear of rock to the bit body, greatly increase

the wear resistance and stability of the bit, and improve the service life of the bit.

The coal field geological drill made by PDC series is suitable for hard and wear-resistant and other complex formations.

Since its launch, the series products have been widely recognized by customers with stable and reliable quality and excellent cost performance.

G,Mantle series pdc cutter for oil

The interface between the diamond layer and cemented carbide matrix of Mantle series PDC is composed of a convex structure with water droplet flow line on the arch surface. This structure is unique in design, and the residual stress on the interface is reduced to extremely low.

Mantle series has made comprehensive improvement in the manufacturing process, greatly improving the microcosmic and macroscopic anti-collapse ability of the diamond working layer, and it is the most excellent product series with anti-shock performance in HMR products.

Another outstanding advantage of this series is its sustained high abrasion resistance, which can remain high in the later life of the drill teeth.

H,V series cone - shaped PDC cutter

The v-series pdc cutter are designed with the shape of sharp cone and the diamond layer is thicker. Meanwhile, innovative tooth shape design is applied to ensure the products have excellent impact resistance and wear resistance.

The bit made of v-series diamond composite teeth can significantly improve the drilling speed and penetration footage.

Suitable for hard and difficult drilling.
