What material is pcd drill composed of, are used in what fields?

PCD bit, also known as polycrystalline diamond bit, is a bit composed of polycrystalline diamond (PCD) composite sheet and carbide matrix. PCD composite sheet is made of diamond particles and metal binder sintered at high temperature and pressure, with extremely high hardness, wear resistance and thermal stability, while the cemented carbide matrix provides support and strength for PCD composite sheet.

PCD drill material composition:

PCD composite sheet: composed of diamond particles (about 80-95%) and metal bond (about 5-20%). Diamond particle is the core of PCD composite sheet, giving it high hardness and wear resistance; The metal binder binds the diamond particles together and provides a certain toughness and strength.

Carbide matrix: usually made of tungsten cobalt carbide, with high strength, toughness and wear resistance, can provide good support and heat dissipation for PCD composite sheets.

Application areas of PCD bit:

With its excellent performance, PCD drill bits are widely used in the following fields:

Building construction: Used for cutting reinforced concrete, masonry, ceramics and other building materials, such as drilling, coring, grooving, grooving, etc.

Road construction: Used for cutting asphalt, concrete and other pavement materials, such as marking, repairing, milling, etc.

Mining: Used for mining a variety of hard ores, such as oil, natural gas, coal, metal ore, etc.

Machining: Used for machining hard materials, such as tools, molds, bearings, etc.

Other fields: It can also be used for the processing of glass, ceramics, stone and other materials.

Advantages of PCD bits:

High hardness and wear resistance: the hardness of PCD bit is 5-10 times that of ordinary carbide bit, and the wear resistance is 100-200 times that of ordinary carbide bit, so the service life is long and the drilling efficiency is high.

Sharp and wear-resistant: PCD bit uses diamond particles as cutting edge, sharp and wear-resistant, can maintain long-term sharpness.

Wide range of application: PCD drill can be used to cut a variety of hard materials, a wide range of application.

Environmental protection: PCD drill does not produce sparks in the cutting process, no pollution, good environmental protection.

Shortcomings of PCD bit:

High price: The price of PCD drill bit is higher than that of ordinary carbide drill bit.

Poor impact: the toughness of PCD bit is not as good as that of ordinary carbide bit, so it should be used with caution in the condition of high impact.

Difficult to process: The manufacturing process of PCD drill is complex and difficult to process.

In general, the PCD bit is a high performance, high efficiency drill bit, suitable for cutting a variety of hard materials. With the advancement of technology and the reduction of cost, the application of PCD drill bits will be more extensive.
