Drilling Tool Manufacturer in China

CHINA DRILLING is a drilling tool manufacturer and supplier located in China. Our products include drill rod,core barrel, impregnated diamond core drill bit, diamond reaming shell, PDC drill bit, casing shoes, and more, which are extensively used in such applications as geotechnical exploration, mining exploration, oil exploration and hydropower station grouting projects.

2. Impregnated Diamond Core Drill BitThe impregnated diamond core drill bit significantly outperforms the successful series range in both drilling speed and bit life;
  Protects the diamond from oxidation and surface degradation during manufacturing;
  Inhibits the premature "pull- out" of the diamond;
2. Diamond Reaming Shell The recommended practice is to alternate two reaming shells in each hole drilled to maintain hole diameter. When changing bits, the diamond reaming shell should be checked for wear using the bit and shell wear gauge. Failure to observe these recommended practices could result in a poorly stabilized bit or an undersized hole requiring costly reaming. Our diamond reaming shell ...
2. Diamond Core Drill Bit (Natural Surface Set) China Drilling offers a wide variety of designs for natural surface set diamond core drill bit. Our selection includes a variety of crown profiles, diamond grades and stone sizes as well as erosion-resistant features. Our natural surface set bit can be very cost effective when drilling in soft sedimentary rocks.

2. PDC Drill BitOur PDC drill bit is ideal for drilling in soft to medium sedimentary formations which are homogeneous and suitable. The PCD cutters are available in several sizes and located to yield maximum penetration rate and long life depending on the application. The PDC drill bit is constructed with a tough, wear-resistant matrix body and gauge reinforcement.
2. Casing ShoeChina Drilling casing shoe is a heavy duty product that can match up to the toughest formations. Using a very resilient matrix to optimize diamond retention, they will hold up in very abrasive, unfriendly formations.
  The casing and rod shoes are threaded to the end of the outer drill string for penetration through ...
2. Drill Rod To reduce the friction between the walls of the hole and the drill rod, apply rod grease to the surface of the drill rods. Rod grease also reduces in-hole vibration, increasing tool and equipment service life.
  ...
2. OvershotThe compact overshot has been modified to protect against accidental release of the core barrel. This Ezy Lock Overshot is ideal for surface application when the hoist is above ground.
  Ezy Lock Sleeve provides a quick, one-handed rotation of the sleeve to lock the lifting dogs.
  Quick Release Safety Pin locks the overshot head to the spearhead point.
2. Core Barrel Spare PartsChina Drilling offers a field proven standard core barrel for use with rods. It consists of the head assembly, inner tube components, and outer tube components. They include 1.5m/5 ft and 3m/10 ft core barrel and can let the drill core sample into the inner tube as well as pick up the cores from the core barrel. You can get a core sample of 1.5m 5 ft and 3m/10 ft.

We continually work to ensure the quality of our diamond reaming shell and PDC drill bit. For instance, the raw materials we use are acquired from world renowned manufacturers, and are tested numerous times to ensure that only qualified materials are used in making our drill bit, casing shoe, and other products. Advanced processing equipment and manufacturing technologies allow us to ensure drilling tool size precision and performance. In addition, our diamond core dill bit, drill rod and other drilling tools are manufactured in line with the DCDMA standard, Boart Longyear standard, and Sweden's standard. China Drilling staff members are given multiple trainings to ensure the standard production of products and minimization of errors. Finally, all our water swivel and hoist plug as well as other products go through 5 levels of testing before being delivered to customers.

We take many steps to control production cost, so we can provide high quality, competitively priced drilling tool to our clients. Bulk purchasing and long term relationships with suppliers help reduce our material purchasing cost, and automated CNC machine tools ensure not only processing precision but also production efficiency. The in-house production of components and parts used for our impregnated diamond core drill bit and head assembly also enables us to greatly reduce production costs.

Due to the reliable performance and reasonable prices of our drilling tool, they are well received by customers from Canada, the USA, New Zealand, Chile, Mexico, Peru, UK, Turkey, Mongolia, Russia, Thailand, Philippines, Australia, Finland, France, Spain, Egypt, and more. In order to better serve customers, we also manufacture PDC drill bit, core barrel spare part, and other drill tool, according to customers' requirements. Our easy access to airports and seaports enables us to deliver goods quickly and at reduced shipping charges to our customers. If you have any drilling tool needs, please don't hesitate to contact us. We look forward to doing business with you.
