Tungsten Carbide Sintered Body Drill Bit

98mm Tungsten Carbide Sintered Body Bit

Our 98mm tungsten carbide sintered body bit is manufactured from high-purity tungsten carbide raw materials via integral high-temperature sintering technology, eliminating weak welding interfaces that commonly exist on conventional drill bits. The monolithic sintered structure delivers outstanding compressive strength, abrasion resistance and impact toughness, making it a reliable drilling solution for medium-hard to hard rock formations.
Available with customizable cutting face layouts, internal flushing channels and bit profiles, this 98mm carbide sintered bit is engineered for geotechnical investigation, mineral exploration, water well drilling, and shallow engineering foundation drilling. Uniform density distribution across the entire bit body ensures consistent wear resistance during continuous drilling, effectively reducing bit replacement frequency and lowering overall drilling operation costs.
We support custom grade formulations of tungsten carbide sintered bodies, thread specifications and surface treatment options to match diverse rock conditions including sandstone, limestone, weathered granite and mixed broken strata. As a direct manufacturer, we strictly control raw material mixing, sintering temperature and precision machining processes to guarantee stable quality and short lead times for global bulk buyers, drilling contractors and trading companies.
