This specification of drill bit core is suitable for small shallow hole scenarios. Its advantages focus on "efficient cutting of soft soil + slag removal and blockage prevention + flexible adaptation to small scenarios", perfectly matching the lightweight drilling needs of small-scale geological exploration, local irrigation of farmland, and simple pile foundation in rural areas.

Its key performance is optimized around "lightweight and efficient" : Firstly, the three-edge cutting edge is made of wear-resistant alloy material, and the cutting edge Angle is precisely adjusted. When facing clay, silty clay, and loose sand layers, it can quickly "cut" the soil layer structure, achieving a breakthrough through soft soil as easily as cutting tofu, avoiding drilling jamming caused by insufficient cutting force. Second, the width and depth of the slag discharge channel between the three cutting edges are reasonably designed, allowing soil debris to be smoothly discharged along the channel. This effectively eliminates the problem of stuck drilling caused by slag accumulation in the hole from the root, ensuring the continuity of shallow hole operations and eliminating the need for frequent machine stops for slag removal.

The application scenarios are highly in line with actual needs: In small-scale geological exploration shallow-hole operations, soil layer sampling can be completed quickly, reducing exploration time consumption. When constructing local irrigation holes in farmland, qualified holes can be drilled without complex equipment to meet the irrigation water demand. When drilling simple pile foundation holes in rural areas, it can ensure the regularity of the hole shape and lay a foundation for subsequent foundation construction. It is compatible with small and medium-sized drilling equipment at the same time, and is flexible in transportation and operation. It is the preferred tool for small soft soil drilling projects to balance cost and efficiency.
