Operation Steps Of Concrete Core Drilling Machine

Operation steps of concrete core drilling machine:

1. Install a hollow drill bit of appropriate diameter.

2. Move the drilling hole to the required working place, fix the drilling hole with expansion screws, adjust the anchor screws to stabilize the drilling machine, or fix the drilling and coring machine with a heavy enough base plate to prevent the machine from moving during drilling and coring.

3. Connect the water source and check whether there is water flowing out.

4. Start the generator and turn on the circuit switch.

5. Rotate the handle to gently contact the drill bit with the cut part. When the drill bit is cut into about 10mm, the screw in speed can be accelerated by pressurizing the handle.

6. After cutting, keep rotating and lift the drill bit. When it is about 5mm away from the surface of the test piece, turn off the power supply. The drill bit leaves the surface of the test piece and turn off the water source.

7. Remove the fixing bolt, drag it away from the coring machine, and take out the sample with a clamp.

8. When in use, the drill bit shall be prevented from hitting hard objects to avoid damaging the drill bit.
