i have some 1/2 rebar i need to cut in old contrete, to get the pieces apart, i have a cheap chinese 24 inch long pair of bolt cutters will these cut the rebar or just put a dent in the cutters ???

Rebar is pretty soft, shouldn't hurt the jaws, but it will probably hurt your arms. Have you tried actually fitting the jaws around the rebar? I'd be surprised if 1/2" will fit far enough into the jaws to make it cut with a reasonable amount of effort.

Cut off wheel should make pretty quick work of rebar and you'd be able to cut it off flush ... assuming you can get the grinder in there.

They should work OK., especially if you just lay the one side of the cutter on the ground and use your weight on the other arm. Kinda like a paper cutter. We made a little saddle type thing to keep the cutter from flopping over when we put the weight to it.

I hope this makes sense.

An oxy/acetylene torch will make short work of it, but steer away from the concrete as it pops if moisture laden. If you have a lot of cuts, rent a partner saw for $40-$50. The saw can be used to cut the concrete in manageable sizes also.

You will need bigger cutters than 24in if you have many cuts. I agree with GTOFM, Rent a gas powered saw and a couple of blades and make short work of it. Much safer too. Wear spoggles and a face shield.

If small job use a battery 4" cut off tool. In my experience the long handle,36" are better,I have 2 pair about 50 yrs old,jaws have marks. If cutting concrete then rental is better.my 2cts

If it were me, I would just try it. Depends on the grade of rebar, 40 or 60 or whatever, but I believe you will only dent it. Smaller diameter you might be successful. If you put 3' - 4' cheater pipes on each handle, maybe but it more than likely will destroy your bolt cutter. I could be wrong but it's jmo.

Post a pic of what you're trying to do. 24" cutters vs 1/2" rebar, you better be Conan the Barbarian if the jaws open wide enough. We used to use bolt cutters with 4' handles or a 14" Chop saw. A grinder with a good blade will work and I've even used a 7 1/4" Skilsaw w an abrasive masonry blade(looks like a black disc)

A sawzall would work also.

If you have a 4 1/2 inch grinder you can buy one of these 7 inch diamond coated metal blades https://www.homedepot.com/p/RIDGID-7...MC70/204202535 and it's portable if you're cutting rebar out of already cast concrete, they can also be used in a circular saw.

If you're cutting rebar in large quantities for new concrete I'd personally use a 14 inch chop saw. I have one of these Ridgid chop saws that I like really well, https://www.homedepot.com/p/RIDGID-1...1422/301289971

We used a metabo to cut re bar, put on a fiber blade.
