tool for cutting wall to hide wiring

[manni]

Hi,

not sure if this is in the wrong forum but i need to route a wire in the brick work of the bedroom wall, what is the best tool to cut a channel?

Should i use an angle grinder to cut two lines down the wall and chisel out the middle?

I hope you can help

Thanks

Martin

There is a special tool similar to two angle grinders which cuts two groves set depth and distance apart then a cold chisel in a SDS drill with rotor stop will take out material between the two lines with ease. Getting right depth with angle grinder is a bit hit and miss and straight lines not easy either.
