Multitool for chasing

PCeeeee

Will it chase? I need to move a switch over a few cm will a multitool do it? And if so what kind of blade do I need?

Yeah, the cheapest multi tool with any wood or plasterboard blade, but any small hand saw would do the same job.

I wouldn't spend big money if it's just one job.

It's in block?

No I doubt they would do block, blade is pretty light. Great for wood and plasterboard though.

You'd need one of those small 115mm angle grinders with a cutting disc then chisel out in between either manually or with an sds drill and a chisel bit.

SDS Drill. Mark out the hole then drill round the edges with a small drill to the correct depth (use depth stop) then drill a few more across that area and knock the remains out with a brick bolster and lump hammer.

Would you not just hire the right machine for the job, e.g.

Dunno how much that costs, but having read some poor reviews on cheap wall chasers hiring the Hilti would be appealing.

I'd be tempted to use an angle grinder with a concrete blade but I reckon dust extraction and collection is critical if you don't want a house full of dust.

I did the concrete blade on an angle-grinder trick recently - and yes there is a massive amount of dust, but it can be reduced if you have somebody stand over you with a vacuum pointed at the angle-grinder (wearing squints and flogs) and if the situation allows.

For a one-of inside I would go with the sds option. Dust is an incredible nuisance.

Thank you all
