How to remove the expansion plug of the fixed base after the concrete drilling machine is drilled?
This is not good to do, I personally think you can in the expansion plug next to hit a small hole, and then pull out the expansion plug, in fact, the expansion plug is designed to be difficult to pull out, or the fixed is not strong ah
Take the silk cap off first, use a small hammer to smash the screw pole, and then use pliers to clamp the expansion bolt and turn outward.
The grinding wheel cutting machine cut directly on the line, if you need to decorate, can be used to hammer the expansion bolt surrounding concrete destroyed (almost a 8cm thick), and then the fine stone concrete leveling can.
