cutting the cement wall / wallchaser / electrical piping

how cutting the cement wall?
for cutting the wall, We can use a wall chaser to cut the wall, but if this equipment is not available, we can use a mini angle grinder.
1- For this purpose, we first groove the wall with a granite cutting disc
2 - Then we drain the grooved area using an impact drill
3 - And finally we put the pipe inside the wall
