High Quality Tungsten Carbide Ballistic Tips for Drill Bits
High quality tungsten carbide ballistic tips for drill bits
Wedged/crested chisel button
Chisal compacts are on DTH bits and roller cone drill bits for soft formation where fast penetration rates are possible and tooth breakage is minimal.
We have a verity of types of carbide button, such as spherical buttons, ballistic buttons, conical buttons, wedge buttons, wedge crested chisel, wing tip, spoon buttons, flat-top buttons, serrated buttons, sharp claw, auger tips, road digging buttons and so on.
Tungsten carbide button is widely used in petroleum drilling, snow plow equipment, cutting tools, mining machinery, road maintenance and coal drilling tools.It is also can used as excavating tools for Tunneling, quarrying, mining and Construction. In addition, it can be applied as drill accessories for rock drilling machine and deep hole-drilling tools. They have good impact toughtness and excellent wear resistance.

To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer's requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of High density hard alloy wear resistant cemented tungsten carbide plates
1st,Mass production,press the raw materials to shape blanks,
Notes: all carbide plates blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide plate clean and nice surface
