The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.

What Are Spiral Drill Bit Teeth?

2. Marine Construction When constructing offshore platforms, bridges, or wind farms, the stability of foundations is paramount. Hammer drilling provides a reliable method to secure pilings and conduct deep foundation work, ensuring that structures can withstand harsh marine conditions.

3. Environmental Assessments Environmental scientists often employ submarine hammer drilling to collect sediment cores and geological samples from the seabed. This data is essential for assessing the health of marine ecosystems and understanding sedimentology for future projects.

4. Renewable Energy Projects With the rise of offshore wind energy, submarine hammer drilling is increasingly used to install the foundations for wind turbines. The ability to achieve deep penetration in various seabed conditions makes this method invaluable in the renewable energy sector.

5. Enhanced Safety Safety is a paramount concern in drilling operations. DTH hammer drilling minimizes the risks associated with traditional drilling methods, such as drill string failures or excessive vibration. The compact design of DTH equipment also allows for easier handling and reduced risk of accidents on job sites.

- Enhanced Efficiency Their design allows for quick and efficient cutting, reducing downtime during drilling operations.
