various types hard alloy drill buttons

[The features of Chinese tungsten carbide drill buttons]

1.The tungsten content is as high as 99.95% or more , the strength and hardness is both excellent.

2. The high precision cemented carbide drill buttons density is uniform.

3. With excellent wear resistance, can be used repeatedly.

4. It has good impact toughness, and faste speed of drilling and digging .

5.After fine grinded in centerless grinding machine, precise size, welding firmer,and the tooth is not to drop.

6. Long service life.

7.The ball tooth drill head passivation using cycle is long, is conducive to saving auxiliary working hours, physical labor and reduce workers to speed up the project..

Q:What is tungsten carbide ?

A:tungstencarbide is a hard material used in machining tough materials such as carbon steel or stainless, as well as in situations where other tools would wear away, such as highquantity production runs.Most of the time, carbide will leave a better finish on the part, and allow faster machining. Carbide tools can also withstand higher temperatures than standard high speed steel tools.

Q: Which grades are useful in earth drilling or boring applications?

A: In many respects the characteristics of the grades employed for earth drilling and boring represent a compromise between the characteristics that are important for metal cutting and those that are important for metal forming applications. Grades for earth drilling and boring must possess the highest toughness levels for any given abrasion resistance level, while simultaneously possessing adequate strength levels. The best compromise is usually arrived at by using grades that are based on coarse grain sizes (3 to 8 mm) and relatively low Co levels (6 to 16 wt. %).
