Can I use a portable bandsaw to cut rebar or do I need something stronger?

A portable band saw will do just fine. When cutting rebar, remember to use safety equipment and tools like globes, safety glasses, and even boots. Rebar is quite heavy and you'll want to protect your hands while lifting, transporting, and cutting it. Put on safety glasses to protect your eyes when cutting rebar because it tends to create sparks as you cut it.

Make sure that when you're cutting rebar, you're doing it at a spacious location to where you're nowhere near flammable objects. Rebar tends to be sold in long rods and for that, you'll really need a big space where you can cut it. When you've measured and marked the rebar, you can proceed to cutting it. Aside from a portable band saw, you can also use a reciprocating saw. When cutting rebar, you might want to step on the rod or bar because it has the tendency to roll around during the cutting process.

You can add rebar safety caps to your list of safety tools and equipment when working with rebar. Straight2Site offers a variety of rebar safety caps, tying systems, and other construction equipment that you'll definitely need for your building projects.

You can use a portable bandsaw to cut rebar, I find it to be the best solution when I can't take the rebar somewhere to cut it. But be careful if the metal is heavy it could fall and dent/damage the floor if you're working indoors of cause injury should it land on you.
