Guizhou Sinodrills Equipment Co. Ltd. - Down The Hole Drilling Tools

Sinodrills dth bits the dth bits is the tool cutting rock. Sinodrills dth bits are made of superior quality alloy steel which is made by timken in u.s. Besides, all our dth bits are using the brand "element six" t.c carbide which provides (the t.c buttons) for boart longyear. In addition art manufacturing technology makes our dth bits with higher and more reliable quality. Different face style makes dth bits suitable for various rock conditions.Flat face: this is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemi-spherical buttons design is the most popular choice. convex face: a classic design for soft to medium hard rock formation which is not so abrasive. This design have very excellent penetration rate but poor in hole deviation if rocks are hard. concave face: medium hard to hard rock formations which is less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation. dgr face: a special design for hard or very hard rock conditions, double gauge row buttons provide very excellent ware-resistance and very longer life time. It is usually used for some bigger diameter dth bits.Besides, we are manufacturing the dth bits with various shanks so they can be compatible with different dth hammers

SINODRILLS DTH Hammers The DTH is the abbreviation of Down The Hole and sometimes it is also called RAB in some markets, then the RAB is short for Rotary Air Blasting. A rotation drill rig, air compressor and the DTH drill string are the essential unit for DTH drilling while the DTH drill string is always made up of DTH drill rods, DTH hammer and DTH bits. As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits. As specialist manufacturer and provider of DTH drilling tools, hereby we recommend our newest generation DTH hammer which is improved by absorbing art technology, selecting superior alloy steel and robust design. It is proved by more than thousands times of test that our newest DTH hammer has longer life , lower air consumption and 15% higher penetration speed compared the conventional DTH hammer in the market. In addition, it can work at the air pressure from 6 Bar to 35 Bar(0.6 3.5Mpa). At last, we developed various type of DTH hammer which can be compatible with DHD, COP, QL, MISSION and SD shank of DTH bits and performs very well. Therefore, the newest generation DTH Hammer is very popular among our customers and has a good market share as soon as it launched in the market.

Sinodrills dth drill pipe dth drill pipes play a significant role in all dth drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality dth tube are durability, accuracy and manageability. Sinodrills dth drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe.the high pressure air is delivered to dth hammer by dth drill pipe, simultaneously it transfers the rotation and press force to the dth hammer. Standard dth drill pipe:diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm, length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;thread 2 38 api reg, 2 78 api reg, 3 12 api reg, 4 12 api reg, 2 38 api if, 3 12 api if special dth drill pipe:the drill pipe for atlas copco ingersol rand t4, schramm t64, atlas copco f6, l6 and l8, and the drill pipe for sandvik driltech d25d40k
