Carbide buttons, also known as tungsten carbide button inserts, are precision-engineered wear-resistant components used in rock drilling, mining, oil & gas drilling, construction, and tunneling equipment. Manufactured from premium cemented tungsten carbide, carbide buttons offer exceptional hardness, impact toughness, and abrasion resistance, enabling drilling tools to withstand the extreme conditions encountered in rock formations.
Installed in drill bits, DTH hammers, roller cone bits, and top hammer tools, carbide buttons improve drilling efficiency, extend tool life, and reduce overall operating costs.
Zhuzhou Century Tool manufactures high-quality carbide buttons in a wide range of sizes, grades, and head geometries for global mining, quarrying, oilfield, and construction industries. Standard and customized OEM solutions are available.
Rock drilling and mining operations expose cutting tools to continuous impact, abrasion, and high compressive loads. Tungsten carbide buttons provide superior performance compared with conventional steel inserts.
Whether drilling soft rock or extremely hard granite, carbide buttons help maximize penetration rates while minimizing tool replacement.
Manufactured using high-quality cemented carbide with optimized cobalt content for an ideal balance of wear resistance and impact toughness.
Every carbide button is produced using advanced powder metallurgy, HIP sintering, precision grinding, and strict quality inspection to ensure consistent dimensions and performance.
Specially developed grades withstand repeated high-impact loading during percussion drilling and rotary drilling applications.
Our carbide buttons maintain sharp cutting performance even in highly abrasive rock formations.
Each batch undergoes comprehensive inspection for:

Our carbide buttons are trusted by customers in:
Zhuzhou Century Tool offers comprehensive OEM and ODM services, including:
Whether you require standard carbide button inserts or customized drilling solutions, we can manufacture products that meet your exact specifications.
Zhuzhou Century Tool is a professional manufacturer of tungsten carbide products with extensive experience in mining and drilling applications.
Our advantages include:
Our mission is to provide durable carbide button inserts that improve drilling productivity and reduce operating costs for customers worldwide.
Carbide buttons are used as cutting inserts in mining drill bits, DTH hammers, roller cone bits, top hammer tools, and oil drilling equipment for breaking rock formations.
Spherical buttons provide superior impact resistance and are recommended for hard, abrasive rock formations. Ballistic buttons offer faster penetration rates and are better suited for medium-hard formations where drilling speed is a priority.
Service life depends on rock hardness, drilling parameters, and carbide grade. High-quality carbide buttons typically last 3 to 10 times longer than conventional steel inserts.
Yes. Zhuzhou Century Tool manufactures customized carbide buttons in various sizes, head shapes, and material grades according to customer drawings or application requirements.
The ideal grade depends on factors such as rock hardness, impact load, drilling speed, and operating conditions. Our engineers can recommend the most suitable carbide grade for your drilling application.
