Chopping Concrete


I have to chop a 3' long by about 5" wide chase. I need to be careful because the concrete I'm chopping is only about 10" wide. What is the best tool for this. Hopefully something I can rent form HD. THanks.

Got a picture?
Not a good thing.
Your going to really weaken what's still there.
Any idea on how thick it is? A hammer drill to drill a test hole would be nice.

Chopping Concrete


We need to remove this piece of baseboard and my plumber is going to cut it out and run a pipe right next to where you see the baseboard.

Chopping Concrete


didn't say how deep this chase has to be,,, we cut 1" deep w/4" grinders,,, perhaps you can rent them from apron/vest stores but they're not much if you can't,,, buy diamond blades there OR thru ebay ($ 3 ea ),,, make a series of cuts 1/2 OR 3/8"" apart & parallel then chip off the remaining conc - easiest way i know

caution - its dusty work & will probably be illegal someday if epa & other like-minded weenies have their way

What do you mean chipping of the fins? We are gonna cut the baseboard at each end and then he is just gonna connect a pipe in the concrete were the baseboard run was because now that is an entrance into a room. The pipe has to be moved over a little because now it is run over the tile. He is gonna add some fittings etc.

A grinder is still the best bet?

scrolling up will refresh your memory w/the diamond blade kerf method,,, what's left 'tween the sawcuts are call'd ' fins ',,, you can probably remove them easily w/brick chisel & framing hammer.

when working in the city sawing/coring/drilling/conc demo, the 4" grinder was used frequently,,, is it the best ? i have no idea but we did that work for a living

you could just make 1 sawcut 5" w X 2" deep IF you could find the blade OR stack 'em together similar to a hgwy grinder,,, unfortunately, it would take mighty joe young helping king kong to handle the torque of the saw
