Rock Drill Bits

As the world changes,our values remain the same.With 23 years of focusing on tungsten carbide and tungsten carbide tools.Carbide button and steel is the most important for rock drilling.

The spherical tooth series bit has a long passivation life cycle, and its non-grinding life is about 5-6 times that of the same diameter blade bit bit. It is beneficial to save auxiliary man-hours, reduce workers' physical labor and speed up engineering.Therefore, the taper connection and threaded connection button bits of different diameters are widely used in all kinds of hard and brittle rocks with drill rigs for rock drilling..Swedish engineering and technical personnel believe that the combination of button bit and hydraulic rock drilling rig is a good match for modern rock drilling technology..

In the past 20 years, the domestic and foreign button bit series have developed rapidly. With the rapid perforation of hydraulic rock drills, the goal of saving auxiliary man-hours for rock drilling and increasing industrial drilling speed has been achieved..

Compared with the traditional chip bit, the cylindrical bit has the characteristics of long grinding cycle and fast drilling speed.Mainly divided into the following categories:
1.DTH bit
The down-the-hole column tooth bit is a kind of drill bit used in conjunction with the down-the-hole impactor. It is used for drilling operations through splines and impactors. It is widely used in open-pit mines, quarries, hydropower projects, and drilling of water wells. , Excavation side pillar support, etc.It is divided into: low pressure DTH column tooth bit, medium and high wind pressure DTH column tooth bit.The down-the-hole cylindrical bit is used in conjunction with the down-the-hole impactor, which has the characteristics of straight drilling, high speed, and deep drilling.So it has been widely used in recent years.
2.Threaded connection column tooth bit
The threaded connection column teeth are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (air drill rods). Through different forms of threads and drill rods, drilling operations are carried out. The diameter of the drill bit is determined by 32-203mm, mainly used in the mining of underground mines, open-pit mines, blast furnace openings in steel mills, etc.Fast speed and easy grinding.
3.Taper connection column tooth bit
The taper connecting column tooth bit is mainly used in conjunction with the pneumatic rock drill and the taper rod. It is connected with the drill rod through the taper to perform drilling operations. It is mainly used for secondary crushing in mines and anchor rod support.

Nokia N97 Mini doesn?t need any introduction as such and the company has made it a point that it makes a mark when it comes to market. Accordingly you?ll get a hell lot of offerings packed into it. Have a look in the following list.

Nokia N97 Mini is having a QVGA display of 3.2 inches and it is a touch responsive screen that has got the power to reflect 16.7 million colors at 640 x 360 pixels resolution. The proximity sensor will automatically turn-off the display when not in use and the gadget will automatically rotate the display through its accelerometer sensor. It will also recognize handwritings and thus will surprise you more. The slide-out full QWERTY keypad gives it a PC or laptop feel and helps you to explore an exceptional way of mobile technology. This chubby looking phone measures 1.42cm deep by 5.25cm wide by 11.3cm tall and modestly weighs 138 grams.
This highly professional communication tool has come up with messaging services like Text Messaging, Multimedia Messaging, Push Email (SMTP, IMAP4 & POP3), Email with Attachments, Email Web Widget and Instant Messaging.Nokia N97 Mini can never let you down as its Symbian Operating System makes it immensely powerful while for further concentric drill bits support there is S60 5th Edition software of 9.4 version.

Its high-end capabilities have been rendered on a greater extend through its GPS navigation system powered by A-GPS support. Integration of Nokia Maps application and Digital Compass make the process even more spotless.Nokia N97 Mini is a master in data sharing and connectivity and its compatibility for these tasks has been confirmed through 3G HSDPA, Bluetooth with A2DP, WLAN Wi-Fi UPnP Support, Micro USB, EDGE and GPRS options.

Exploring the web world through the handset will be a completely new experience and thus it is carrying WAP 2.0/xHTML and HTML browsers assisted by RSS Feeds.The gadget's business capabilities don?t really need any extra introduction and so the company has adequately given it the document viewer attribute through which one can dth drill pipe go through Word, Excel, PowerPoint and PDF virtual document formats.

Coated cemented carbide currently represents 80-90% of all cutting tool inserts. Its success as a tool material is due to its unique combination of wear resistance and toughness, and its ability to be formed in complex shapes. Coated cemented carbide combines cemented carbide with a coating. Together they form a grade which is customized for its application. Cemented carbide is a powdery metallurgical material; a composite of tungsten carbide (WC) particles and a binder rich in metallic cobalt (Co). Cemented carbides for metal cutting applications consist of more than 80% of hard phase WC. Additional cubic carbonitrides are other important components,Tungsten Carbide Rods especially in gradient sintered grades. The cemented carbide body is formed, either through powder pressing or injection moulding techniques, into a body, which is then sintered to full density.
