Rebar is one the most versatile and cost-effective construction materials. It can also be used for many other purposes than reinforcing concrete. It can seem daunting to work with rebar if you have never done so before. This guide will show you how to cut rebar like an expert in a matter of minutes.
What You’ll Need
Rebar can be cut in a variety of ways, some better than others. I recommend using a power tool to cut rebar. Rebar can be labor-intensive and can eat through hacksaw blades.
These tools will help you get the job done, regardless of whether you’re using a saw, grinder, or simple hacksaw.
- Chop, miter, or angle saw (a bench grinder, circular or hacksaw can be used in a pinch).
- Cut off or diamond blade
- A bench vise or workbench may be useful depending on the type of material you are cutting.
Step 1: Measuring The Job
Rebar is usually sold in lengths of around 6.1m. It’s possible that you will be working with longer lengths of rebar so it is important to take precise measurements. You will need to measure the length of the rebar if you have to bend it in any direction.
You can use your tape measure to measure your cuts. To mark the rebar, you can use chalk to mark where you want to start your cut.
Step II: Making The Cut
Safety First
Remember that you are cutting metal with a metal knife when working with rebar. You will see metal shavings flying around the air, as sparks are generated. You should be cautious.
You should always wear safety equipment such as gloves and goggles. If you can, wear long sleeves and work boots.
Traditional Methods
The way you approach the cut depends on what type of saw you have.
You can make fast work of any job with a circular saw, mitersaw, or chop saw.
Place the rebar on the saw. Make sure the mark for the cut is under the saw’s blade. Turn on your saw and begin cutting. Don’t apply too much downward pressure to the saw during the cut. Before you remove the cut rebar, allow the blade to stop completely.
Grinders
An angle grinder or bench grinder can be a better alternative to a saw equipped with a diamond blade. Professionals often use an angle grinder to prevent damage to their diamond blades.
It is a good idea to replace the cutoff wheel of your grinder if it shows signs of wear before you get to work.
It is a good idea to place the rebar on saw horses or in a bench vise prior to using a grinder. You can roll rebar when you cut it. To avoid this, secure it in a vise. Or use your free hand for gripping the rebar while you cut.
When you are ready to begin cutting, turn on the grinder. Place the grinder parallel to the rebar and start your cut. Let the grinder do the job and use light pressure to get the wheel through the rebar.
Last Resort
You can use a basic hacksaw to cut through the rebar if you have a very limited toolbox. It takes patience and strength to learn how to cut rebar using a hacksaw. However, using the right blade can speed up the process.
A blade with 14-18 TPI is best for cutting heavy metals. Blades that are designed for general or thin metal cutting are not compatible with rebar. You’ll spend hours trying to cut your first rod without the right blade.
To prevent the rebar from rolling while you are cutting, position it in a bench vice. Use steady strokes to cut away your self.
The Final Word
Although it might seem daunting at first, cutting rebar is an easy project that any serious DIYer should be capable of tackling. These tips will make it easy to quickly cut rebar.
