PDC Bits

The HT2843 PDC bits adopts 13mm claw-type PDC cutters and a large blade design. PDC bits can drill medium to medium-hard formations. PDC bits is recommended to drill interbedded shale, mudstone, cementitious sandstone and carbonate rock with medium compressive strength.



As a drill bit manufacturer, we are proud to offer a range of high-quality PDC bits that are designed to deliver exceptional performance in a variety of drilling applications.

Our PDC bits are manufactured using advanced technologies and the highest quality materials to ensure optimal durability, reliability, and efficiency. With their innovative designs, these bits are capable of delivering fast, smooth drilling performance even in the toughest conditions.

One of the key benefits of our PDC bits is their exceptional cutting efficiency, which allows them to quickly and easily penetrate hard rock formations, making them ideal for use in oil and gas drilling, mining, and geothermal drilling applications.

In addition to their cutting performance, our PDC bits are also designed to reduce wear and tear on your drilling equipment, helping to extend the lifespan of your tools and minimize downtime on your drilling projects.

At our company, we are committed to providing our customers with the highest quality drilling tools and accessories, and our PDC bits are no exception. So whether you're drilling for oil and gas, mining minerals, or exploring for geothermal energy, you can count on our PDC bits to deliver the reliable, high-performance drilling you need to get the job done right.

Grand Construction PDC Drill Bits

Polycrystalline diamond material for polycrystalline diamond composite (PDC) drill bits is one of the most important material advances in oil drilling tools in recent years. Fixed head drill bits rotate as a single unit and do not contain separate moving parts. When fixed head bits use PDC tools, they are often referred to as PDC bits.

Polycrystalline diamond composite (PDC) bits are made with synthetic diamond tools made of steel or base material.PDC bits have revolutionized the drilling industry with a wide range of applications and high drilling speed (ROP) potential. Polycrystalline diamond composite (PDC) bits are the workhorse of the oilfield. Features such as tool type, tool layout and insert geometry are constantly being evaluated and improved to create value and reduce drilling costs.

PDC bits range from 1" to 18" and are used in HDD horizontal directional drilling, oil and gas, geothermal, water wells, construction and mining.

PDC bits are designed and manufactured in two structurally different styles:

Matrix-body bit

Steel-body bit

Both offer significantly different features, and since both types have certain advantages, the choice between them will depend on the needs of the application.
