How to Cut Rebar

Like any task that requires using power tools, cutting rebar may seem a hard task to learn at first. However, it’s not as hard as it seems. When practicing using rebar, all you need is to make sure to protect yourself entirely by wearing eye and ear protection and gloves. Here’s how to cut rebar using different kinds of tools.

How to Cut Rebar

• Rebar can be cut using different tools such as hacksaw, portable bandsaw, reciprocating saw, or angle grinder. With chop saws, miter saws, and circular saws, you save time as they do the job quickly.
• As rebar is fabricated in lengths of around 20 feet, you need to measure and size it accurately. For measuring, use a tape measure. When it comes to marking your cuts, use white chalk.
• Hold the rebar firmly because rebar usually recoils back.
• Bend your rebar. Lay it on the ground, then, get a large metal pipe into which you would put the rebar. Keep a distance of 6 inches from the starting bending point. Press with your foot to fix it firmly in place, putting your foot 16 to 12 inches from your bending point. Level the rebar until it bends and take the angle you want. 

How to Cut Rebar Using a Power Saw

Each type of saw require a specific manner with which to perform the cuts, but there are general, standard steps to follow when using power saws:

• Place the rebar in the saw, with the cutting mark just below the saw’s blade.
• Turn your saw and start cutting.
• Leave the saw at its own natural speed, and don’t try to pressure it.
• Before unplugging the saw, wait for it to stop completely.

CUTTING REBAR Using a Hacksaw

Especially with hacksaws, it’s highly important to have an accurate, proper blade to make the process easier and quicker for you. Otherwise, you’ll invest a lot of effort and you’ll need to be really patient. Get a 14-18TPI blade that is made specifically for heavy and thick pieces of metal. Other blades would only consume your energy for nothing.

Place your rebar firmly on a device on your workbench so it doesn’t roll. Using the full length of the blade, cut through the rebar straight and steadily.
