What Is a Road Core Drilling Machine?
A road core drilling machine is a tool used to cut and collect samples from road surfaces. It is made for asphalt and concrete roads. Engineers use it to test road quality in highways, airports, and city roads.
This machine uses a hydraulic system and a diamond drill bit. It cuts clean core samples without damage. These samples are used to check material strength and aging.

Working Principle of Hydraulic Coring Machine
The hydraulic coring machine uses hydraulic power to spin the diamond drill bit. It drills through the pavement with speed and force. A lifting system moves the bit up and down.
- A diamond core bit cuts the material accurately
- The hydraulic motor gives strong and smooth torque
- The vertical guide keeps the drilling straight
- Cooling water prevents overheating and cracking
Common sample sizes: Φ100mm, Φ150mm (also supports Φ50–200mm range).
