Can "Multifunction Tools" cut concrete?

[agulesin]

Hello Everyone!

I need to channel out the concrete floor in our house to run low-voltage (telephone, network) cables across doorways. I've been thinking to invest in a "Multifunction Tool" such as Bosch PMF 250 or similar for this and other tasks.

Has anyone tried to cut concrete with these vibrating tools? All the bits advertised are for cutting wood or metal or grout cleaning; not exactly the same hardness as concrete!

I could do it with an angle grinder and suitable blade but getting into the edges of the doorway will be impossible. And the wife will kill me if I fill the place with dust although I could rig up the vacuum to try to catch most of it. I assume the vibrating cutters would raise less dust.

Please let me have your opinions!

Many thanks...

It's an angle grinder for this one, I'm afraid......with a sharp cold chisel to help in the corners.
Drilling some holes in the corners would also help a bit.

Wet the floor to minimise dust and angle grinder for channel you can get into corners with one of these on an sds drill.

Tell you wife to get the broom out.

Get a proper chasing machine with dust extraction.

Trying to cut concrete with a multitool would be a bit like trying to bail out a sinking boat with a teaspoon!

Obviously none of you have been on a sinking boat. Give me a man with teaspoon over an electirc bailer any day!

How does the sailing saying go.. Best bailer in the world is a scared man and a bucket!!
