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. %).
