Basic Info.
Product Description
Application: Main used for making mining tools, carbide button tips are pressed into pre-drilled holes in the cone of the bit to achieve better wear resistance and excellent cutting abilities for drill bits, like DTH Drilling Bits, Tricon Rock Roller Bits, Special bits required for rock drilling.
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. 
Grade list of carbide button mining tips:
| Grade | ISO Grade | Density (g/cm3) | Hardness HRA (ISO3738) | Grain Size | Bending Strength(N/mm2) | Main Using purpose |
