Product Description

Application for cemented carbide octagonal drilling tips: 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 (within +/- 0.1 mm).

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. 

Sizes: Both standard and non-standard carbide tips are available from Zhuzhou Eastern Carbide. We have many successful projects for our clients to make the customized tungsten carbide tips, we can make your own design become real product and perfectly match your requirements.  



Grade list of cmeneted carbide octagonal drilling tips:
