The 20-type engineering drill rig utilizes high-speed cutting technology, paired with thin-wall diamond drill bits, and is extensively used for drilling and core extraction in fields such as engineering construction, municipal engineering, equipment installation projects, and building quality inspection projects.

1. Core samples are taken from concrete, asphalt pavements, limestone foundations at roads, airports, ports, and dams for compression and flexural strength tests.

2. Install bolt holes for large machinery equipment.

3. Installation of bridge handrails and traffic safety guardrail drilling.
