Application(drilling and coring):

This ideal for vertical coring of pavements and slabs. It has an 6in (152mm) drill bit capacity. The stable platform with leveling screws, a heavy-duty column and smooth, precision-feed system combine to make this model the ideal choice for large projects. The 6.5hp four-cycle manual start gasoline engine drill allows the user to operate independently of power supplies with minimal setup time and faster drilling.

The unit easily adapts to mount to a pickup truck and carriage travel is 24in (610mm).

The 20-type engineering drilling rig adopts high-speed cutting technology and is matched with thin-walled diamond drill bits. It is widely used in drilling and coring of engineering construction, municipal engineering, equipment installation engineering, and construction quality inspection.
1). Take cores on concrete, asphalt pavement, and limestone bases such as highways, airports, ports, and dams for compressive and flexural tests.
2). Install large machine equipment to drill anchor bolt holes.
3). Handrails for bridge handrails and traffic safety guard rails are installed.

Features:

1.) It adopts dual-post structure and spiral feeding mode, with good stability and simple and labor-saving operation. With wheels, easy to move.
2.) Using high-speed cutting technology and thin-walled diamond drill bits to drill and cut high-strength reinforced concrete, with high drilling efficiency, accurate hole position, smooth hole wall, good hole forming quality, complete and smooth core sample, and low vibration. No damage.
