Key Characteristics
🔹High Hardness and Wear Resistance: The front end of the drill bit is embedded with diamond particles, the hardest natural material. This allows it to easily cut through high-hardness materials like granite, ceramics, and concrete, with a service life far exceeding that of ordinary drill bits.
🔹High-Precision Coring: Utilizing an annular cutting design, it only drills a circular groove, leaving a complete cylindrical core or sample in the middle. This method is not only highly efficient but also produces very regular, smooth hole walls and intact samples.
🔹High Strength and Fatigue Resistance: The drill rod itself must possess extremely high strength and toughness to withstand repeated tensile, compressive, torsional, and impact loads during the drilling process. This is particularly critical for geological drilling at depths of hundreds or even thousands of meters.
🔹Diverse Specifications: These drill bits are available in various diameters, accommodating hole size requirements ranging from a few millimeters to hundreds of millimeters, making their application scope very wide.
Usage Scenarios
🔹Geological Exploration and Mining: This is their core application. They are used to drill and extract rock cores from underground to analyze geological structures, mineral compositions, and reserves, serving as a key tool for mineral exploration and resource assessment.
🔹Construction Engineering and Testing: Used to drill cores in concrete structures (such as bridges, dams, and buildings) to test the strength, density, and internal quality of the concrete, thereby evaluating the safety of the structure.
🔹Stone and Ceramic Processing: Used to drill precise circular holes in granite, marble countertops, or ceramic tiles, for example, to create openings for installing sinks, faucets, or pipelines.
