what can our new drilling machine do?

This core drill uses a diamond-impregnated drill bit. It employs a high-speed grinding method to create perfect circular holes in materials such as concrete, precast concrete, granite, asphalt, and bricks, while extracting a complete cylindrical core sample. Its unique split-type combined structure not only enables quick assembly and disassembly but also allows the equipment to be easily stored in a draw-bar box, greatly enhancing on-site transport and portability.

Working Principle: Grinding vs. Impact

The core difference between a core drill and a traditional impact drill lies in its grinding working principle. The machine rotates under axial pressure, with the diamond segments grinding the material surface to form an annular groove. Simultaneously, a continuous flow of water reaches the cutting edge through the center of the drill rod, providing lubrication, cooling, and chip removal, ensuring cutting efficiency and tool life.

Key Technical Advantages

1. Accurate Positioning and Stable Operation

Because the drilling hole is strictly concentric with the fixed position of the rig, the drilling hole positioning is extremely accurate. There is no need to drill a fixed expansion hole next to the main hole during construction, which simplifies the process and ensures the hole core is neat and smooth. The equipment exhibits good stability in use, ensuring a smooth and reliable drilling process.

2. Split Design, Portable and Flexible

The machine features a split structure, allowing it to be quickly disassembled into multiple components. All parts can be stored in a dedicated draw-bar box (dimensions 680×550×240mm, weight 8.5kg), making it easy to carry to the construction site or transport between different sites. The repair and replacement of individual parts is fast and economical, significantly reducing maintenance costs.

3. Laser Drill Bit Repair Technology for Lower Costs

The drill part can be repaired with a supplementary length by laser. We offer laser rewelding solutions that allow multiple repairs of drill bits. This innovative design significantly extends the life of the drill bit, saving users the cost of frequent replacements.

4. Multiple Power and Speed Options

The New Drilling Machine is available in several standard configurations (Standard Set 1/2/3) and can be paired with different drive units, such as the METABO angle grinder, HOPRIO brushless angle grinder, and HOPRIO brushless adjustable speed angle grinder. Power coverage ranges from 2000W to 2600W. Output rotation includes both fixed models at 705 rpm and adjustable multi-speed models (378/480/565/632/742/842/844 rpm), adapting to different material and hole diameter requirements.

5. Large Diameter, Deep Hole, and Inclined Hole Drilling Capability

The drilling diameter range is 63-300mm, and the drilling depth can reach 100-700mm (depending on configuration). It also allows for inclined hole angles from 0-45°, meeting the requirements of various complex working conditions such as pipe penetration through walls, electrical and plumbing line installation, and anchor bolt setting.

6. Lightweight Design for Easy Operation

The total weight of the machine is only 28-29kg. Combined with storage in the draw-bar box, it can be easily handled by one person. The design for fast combination and disassembly makes on-site setup and cleanup highly efficient.

Typical Applications

  • Plumbing and Electrical Installation: Creating precise channels for pipes and electrical conduits through concrete walls.

  • HVAC Engineering: Drilling ventilation pipe holes in floors or walls.

  • Structural Retrofitting: Installing concrete anchors and conducting structural strength tests.

  • Geological Exploration: Collecting rock core samples for geological analysis.

  • Road Testing: Drilling core samples from cement or asphalt pavements for quality inspection.

Conclusion

With its outstanding advantages of being split-type and portable, accurate and stable, and economical and durable, the New Drilling Machine core drill provides a reliable solution for drilling in hard materials for modern construction. Whether dealing with reinforced concrete or granite, it helps engineering teams improve construction quality and efficiency with its high-performance, low-impact operation. For professional users seeking portability and cost-effectiveness, this core drill that fits into a draw-bar box is undoubtedly an ideal choice worth investing in.
