Tungsten carbide buttons, also known as carbide button inserts or cemented carbide buttons, are high-performance wear-resistant components used in rock drilling, mining, quarrying, tunneling, oil & gas drilling, and construction industries. Manufactured through advanced powder metallurgy technology, these inserts combine exceptional hardness, impact toughness, and abrasion resistance, making them ideal for demanding drilling applications.
Zhuzhou Century Tool manufactures premium-quality carbide buttons in various sizes, grades, and head profiles for DTH drill bits, top hammer drill bits, tricone bits, anchor drilling tools, and rotary drilling systems. Our products are trusted by customers worldwide for their consistent quality, long service life, and excellent drilling performance.
Drilling tools operate under extreme impact and abrasive conditions. High-quality carbide buttons significantly improve drilling efficiency and extend the service life of drill bits.
Manufactured using high-purity tungsten carbide powder and premium cobalt binders for excellent mechanical properties and consistent quality.
Every carbide button is produced using:
This ensures high density, minimal porosity, and excellent wear resistance.
Our carbide buttons maintain sharp cutting performance even in highly abrasive rock formations, reducing drill bit replacement frequency.
Optimized carbide grades provide outstanding toughness to withstand repeated percussion impacts during drilling operations.
Tight dimensional tolerances ensure reliable brazing, accurate fit, and consistent drilling performance.
The most widely used design for hard and highly abrasive rock formations.
