Tungsten Carbide Buttons For Construction

Tungsten carbide buttons are essential wear-resistant core components for modern construction and infrastructure engineering. Made of high-purity cemented tungsten carbide with optimized cobalt bonding formula, these button inserts deliver exceptional hardness, superior abrasion resistance and balanced impact toughness, perfectly adapting to harsh construction working conditions such as hard rock drilling, road milling and foundation excavation.

Widely compatible with DTH drill bits, rotary drill bits and road milling cutters, our carbide buttons serve diverse construction scenarios, including tunnel boring, highway renovation, water well drilling and municipal foundation projects. They effectively resist high-frequency impact and strong friction, avoiding frequent tool damage and replacement, greatly reducing construction downtime and overall operating costs.

We strictly adopt virgin raw materials and standardized sintering technology, ensuring stable mechanical performance and precise dimensional tolerance of each product. Multiple types of shapes and specifications are available to meet customized construction equipment demands, providing reliable long-life support for global construction engineering projects.
