112mm PDC Core Bit with 1305 Spherical Cutters
The 112mm PDC Core Bit is specially designed for geological exploration, mineral investigation, water well drilling, and other drilling projects involving challenging rock formations. Equipped with 1305 spherical PDC cutters, this core drilling bit provides excellent impact resistance, enhanced wear resistance, and improved cutting stability.
Compared with conventional flat PDC cutters, spherical PDC cutters offer a more impact-resistant cutting structure. They help reduce cutter chipping and damage when drilling through formations containing cobblestones, sandy gravel, conglomerate, sandstone, and fractured rock.
With a carefully designed cutting profile, the
112mm PDC core bit
delivers stable drilling performance and reliable service life in variable geological conditions.
As a professional PDC drill bit manufacturer in China, we provide standard sizes as well as customized PDC core bits according to customers' drilling requirements, formation conditions, and drilling equipment specifications.
The
112mm PDC core bit
with spherical cutters is suitable for various drilling applications:
1. Geological Exploration Drilling
Suitable for mineral exploration, geological surveys, and core sampling projects where drilling formations contain gravel, conglomerate, sandstone, and fractured rock.
2. Mineral Exploration and Mining Projects
Designed for drilling in mining areas with complex geological structures, including cobblestone layers, gravel formations, and broken rock zones.
3. Water Well Drilling Projects
Can be used in water well drilling operations where underground formations contain sand, gravel, sandstone, and mixed rock layers, subject to suitable drilling system compatibility.
4. Geotechnical Investigation
Suitable for engineering geological surveys, foundation investigations, and construction site exploration involving variable rock formations.
5. Infrastructure and Construction Drilling
Applicable to geological investigation for roads, bridges, tunnels, dams, and other infrastructure construction projects.
6. Exploration in Fractured Rock Formations
The impact-resistant spherical PDC cutters help improve drilling durability in formations with frequent changes in rock hardness and broken rock structures.
