Product overview

Core functionalities

Applicable scenarios

Unique advantages

Heavy-Duty Drilling Capacity: Equipped with a 255mm diamond core bit, designed to efficiently drill large holes in reinforced concrete, masonry, and other hard materials.
Variable Speed Control: Adjustable speed settings (two-speed operation) enable precise drilling for different material types and depths.
Hydraulic Power System: Ensures consistent pressure and stability during high-load operations, ideal for demanding commercial applications.
Adjustable Depth Control: Pre-set drilling depth mechanism minimizes over-drilling and enhances accuracy.

Key features

1. Material Technology: Diamond-Impregnated Core Bits

With diamond-impregnated core bits, you can drill through reinforced concrete and masonry with precision and efficiency. The diamond coating ensures long-lasting durability, outperforming standard carbide-tipped bits in abrasive materials.*

2. Interactive Design: Variable Speed Control & Ergonomic Handles

With a variable-speed motor and adjustable ergonomic handles, you can fine-tune drilling pressure and speed for optimal control, reducing operator fatigue compared to fixed-speed models.*

3. Performance Parameters: 255mm Maximum Drilling Capacity

With a 255mm maximum drilling diameter, you can tackle large-scale projects—up to 50% larger than standard core drills—ideal for installing conduits or creating access holes in commercial settings.*

4. Scenario Solutions: Heavy-Duty Commercial Use

Designed for reinforced concrete and industrial environments, this drill rig ensures stability on uneven surfaces via adjustable feet and wheels, making it suitable for continuous operation in construction and maintenance scenarios.*

5. Certification Standards: CE Certified Safety & Compliance

With CE certification, you can ensure compliance with EU safety and quality standards, providing peace of mind for professional users in regulated industries.*
