Tool for breaking up Concrete

[opps]

Soon I need to cut a channel in a concrete path along side my house - probably only about 4m long max, and only 1 course deep - the path has been built up above dpc over the years.

Would my small SDS drill (Katsu!) do the job with enough perseverance, or should I get a bigger one? My concern for bigger is it being right against the wall, so I am guessing better to take it slow and gentle ...

Wouldn't you get a cleaner finish if you run a 9" angle grinder along the perimeter first?

Probably, but I don't have one, and cannot afford to hire one. Although, maybe a mate has one....

Titan- I have their diamond wall chaser. I needed it for a small job at home (our walls are rendered). It only cost about £70 but I now wish that I had paid about £200 for a machine that was better balanced. It really is hard work to use.

In the main, if I want a reliable tool that I plan to use frequently I avoid the likes of Titan, Silverline, Erbauer, etc, but if you are only planning to use them domestically then they are adequate.

You are looking at 2 to 3" depth of cut with a 9" grinder. It might not be enough to cut all of the way through but once you use the breaker it should give you a cleaner finish.

What do you plan to do? Backfill with gravel?

Are you saying you've made 3 warranty claims, or spent £400?

I have 3 of them and I've had 4 replacements, they sit in the back of each van.
I've also got one waiting to go back as someone pulled the handle off.
