Application for our tungsten carbide octagonal inserts for drilling : Fixed on the drill bit by brazing, suitable for soft, medidum hard and hard rock formations drilling.
Two impotant things for brazing:
*Clean surface: Not only means keep the surface cleance, but also need to check the carburization/decarburization carefully.
*Size control: Good size control is also important, size need to be even from the top to the bottom of the tips 

Our tips was done by HIP sintering, it provide extra 30% on bending strength compare to normal quality, which means our tips will be strong enough when meet heavy impact. Also, it will have longer tool life (better wear resistance) for you to use our tips.
*Sinter-HIP is a method of thermal consolidation for cemented carbide wherein the simultaneous application of heat and pressure fully consolidates the carbide during the sintering process.

It is very important to select the right grade to match the using purpose, need to find the perfect balance between hardness and bending strength, so we have to consider the physical properties of the processing object, also the working condition for tools, like running speed, impact. 

1. What is Tungsten Carbide?

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

2. What could our tungsten carbide buttons do?

we developed Tungsten Carbide Buttons in various grades
suitable for use in products like Down The Hole Drilling Bits, Tricon Rock Roller Bits, Special bits required for underground cable laying, etc. We can supply the buttons in ground and tumbled finish which facilitates perfect fitting in shank.
