120mm Flat Top Tungsten Carbide Sintered Body Bit
This 120mm flat top
tungsten carbide sintered body bit
is equipped with standard 2 7/8 REG connection, manufactured by integral powder metallurgy sintering process without brazing joints. Adopting flat-top cutting structure, the bit achieves stable axial load distribution during drilling, effectively avoiding bit deviation in uneven broken rock formations.
Different from segmented welded drill bits, the monolithic tungsten
carbide matrix
owns consistent hardness and abrasion resistance across the whole body. Optimized internal flushing passages are arranged on the flat face to boost cuttings discharge, reduce bit balling and extend continuous drilling time.
Designed for medium-hard, highly abrasive strata, this
120mm flat top carbide sintered bit
is widely adopted in geotechnical investigation, surface mining drilling, water well construction and engineering blast hole drilling. As a professional sintered tungsten carbide manufacturer, we adjust carbide formulation, waterway layout and surface finish based on clients’ actual rock conditions. Bulk orders and customized specifications are available for global drilling contractors, wholesalers and importers.
