Rebar is not a cheap construction material and is not the safest to handle either. If you don’t know how to cut it, you could end up hurting your self and spending more money on materials.
Read our guide below and know everything you need to know before starting the cutting process.
What Is Rebar And What Is It Used For?
Rebar is a common type of steel bar used in concrete making. When steel bars are embedded, the material is transformed into reinforced concrete.
Rebars are able to prevent cracking and collapse of floor slabs, posts, and walls. This material and other reinforcements can limit the placement and severity of concrete cracking, even though every concrete is prone to fractures. It adds structural integrity and strength to the entire undertaking.
Safety Reminders Before Cutting Rebar
1. When cutting metals with a metal blade, its shavings and sparks will be propelled into the air. You must be careful not to injure yourself. Protective gear includes safety glasses, long-sleeved shirts and trousers, gloves, and sturdy footwear.
2. Avoid working near flammable materials and choose an area with good ventilation, away from people and children.
3. To prevent electrocution, dry your hands well before handling the material, and dont use the cutter in rain or damp environments. When not in use, the tool should be unplugged.
An Angle Grinder Is Used To Cut Rebar
Most cutting tasks can be accomplished with a standard 10 cm to 11cm blade. The quality of the angle grinder will determine how successful the process is. As an alternative to hacksaws, this is a very handy tool that makes rapid, rough cuts.
How To Choose An Angle Grinder And Conserve Power
A high-quality angle grinder equipped with a cutting wheel, diamond blades and a cutting wheel is necessary to successfully cut reinforcing steel bars. Metal, pavers, stucco, and tile are just some of the many products that may be cut using an angle grinder.
Choose one that draws 5 to 9 amps as this is the range for the most powerful motors. Also, diamond blades wear over time, so our woodworkers would recommend using this for cutting a piece of rebar.
An Angle Grinder Is A Tool That Can Be Used To Cut Rebar
1. Make sure you are using the right wheel for the material. Ideally, it would be powerful enough to sever steel but sturdy enough to last.
2. Its time to check the materials safety. Clamping it or placing it in a vise is an effective method.
3. Next is to do a vertical incision. Although it may not be the most precise cut, angle grinders are much faster.
Use Power Saws To Cut Rebar
Do not force a saw to do any cutting. Instead, let it relax and let it do the job. Be sure the blade has completely stopped before picking up the finished product.
The quickest approach to cutting this type of material is using a circular, miter, or chop saw equipped with a diamond blade or a large carbide blade.
Circular Saw
The circular saw is one of the most popular power tools because its blades can effortlessly cut through the material. When cutting, make sure you use a saw blade that is designed for metal. You can clamp it in a vise to ensure consistent cutting.
Generally, you may choose between two distinct kinds ofsharp blades for circular saws. Cheaper steel tooth blades that you may need to replace more often are serviceable. Although carbide-tooth blades perform similarly, they can be more expensive.
Reciprocating Saw
Metals may also be cut using a reciprocating saw. Avoid using the oscillating setting. Instead, use the straight setting. The blades will last longer if the speed is reduced.
A TPI (or teeth per inch) of 20-24 is required for thin metals. Choose 18-24 TPI for medium-sized metals; 8 TPI for heavy metals.
Chop Saw
A chop saw is another useful rebar cutter. Similar to a miter saw in operation, but with a much carbide tooth blade. Make the necessary adjustments to how fast it is, and youll be able to make straight cuts through the metal.
Portable Band Saw
Small, portable band saws powered by batteries are readily accessible at home improvement stores and are sometimes even offered for renting.
They dont produce sparks, can make precise cuts, and can be taken everywhere. Really, could there be anything negative to say about it?
Their only significant drawback is that they are too cumbersome to utilize in confined spaces. Trimming may also be tricky when using a portable band saw.
Miter Saw
If you have the right blade, you can also use a mitersaw to cut the material. A miter saw can also make compound, bevel and angle cuts, in addition to the 90-degree standard cut. Metals require specialized equipment for cutting.
Jigsaw
You may use a jigsaw to cut the material efficiently, a very strong portable tool. This tool can handle thicknesses of between 10 and 30 mils.
Maintaining a firm hand and using light pressure when working with a jigsaw are important. Avoid scratching the metal by stopping periodically to apply oil. Stop using the blade and remove it from the workpiece if you have the impression it could break.
Hand-Cutting Rebar
There are several ways to cut through rebar with only your bare hands and a little muscle power.
Hacksaw
The simplest, least expensive, and most time-consuming way to cut rebar is with a hacksaw. A hacksaw is best for cutting through reinforcing metal. It requires patience and strong arms.
You can use a simple hacksaw if only a few bars have to be cut. If there are many bars to be cut, however, the process will be slow, tedious, and time-consuming.
Hacksaw for cutting rebar
- Determine the required size of the rebar by using a measuring tape.
- Put the material on top of a solid table or floor. Make sure the cutting point is not more than an inch from the ground. If the rebar is trembling, it will be difficult to make precise cuts.
- Attach the clamps to your tabletop. The clamps should be placed as close as possible to the intended cutting point of the rebars.
- To create a grove, make a few quick cuts using the hacksaw. Now proceed with slow, firm cuts. You can take advantage of every cutting edge that is available.
Cutting Wheel
Rebar may be easily cut with a cutting wheel. To hold the rebar in its place, use a vise or several clamps. Next, make small gentle cuts. A thicker wheel will cause more friction and take longer to make every cut.
Bolt Cutters
Blades that look like scissors give a bolt cutter its name, and its metal-cutting power may reach up to 2,041 kg. Its a strong weapon capable of slicing into steel.
Cutting Rebar with Bolt Cutters
- Bolt cutters should always be held in both hands with the jaws facing the opposite direction.
- To fully open it, remove the handles from one another and pull them as far as you can.
- Wrap the rebar with the blades center points facing outwards. Cutting at an angle might lead the jaws to distort and slip off the rebar, so be careful.
- Squeeze the handles firmly, and cut into the rebar.
Hydraulic Bolt Cutters
The hydraulic bolt cutter is the easiest and most inexpensive rebar cutter. It’s quiet, lightweight, and convenient.
One must pump the tool to increase pressure which makes cutting the rebar easier. The hydraulic cutter does not require any additional power sources, such as electricity or cables. You should reserve it for little tasks only.
Torch
Since they work differently, you should avoid using oxyacetylene and plasma torches for more substantial projects. After melting, rebar can often have rough edges. The torch-based metal cutting process is more expensive and takes longer.
For snapping rebar, secure it on a vise and burn it with a torch to make it flexible; this method is ideal for smaller projects. Use a pipe to allow you to bend or break it afterward.
Rotary Hammer
A rotary hammer is a great tool for cutting reinforcing bar. Its a more efficient approach that requires less time and effort.
For optimal performance when working with rebar you must switch to the rotation mode and not the hammer mode.
It features a lengthy extension cable, much like any other portable device.
Pincer Pliers
These are utilized more often for tying rebar than for slicing it. Due to their scissors-like design, they do not have the necessary strength to cut through 4-millimeter rebar, but they can slice metal wires.
Other Tools You Can Use To Cut Rebar
Electric Bar Cutters
This list includes an electric bar cutter, which is a very effective rebar cutter. Its a wheeled machine so you can move it from place to place. It is used by professional firms to quickly and accurately cut rebar on the job site.
Every model of this tool has its maximum rebar diameter and a good metal cutting force.
With their help, the user may direct the action. It is undoubtedly the safest and most suitable equipment for a corporation.
Hydraulic Bar Cutters
Hydraulic bar cutters can be used to reduce the risk of injury. This type of material is commonly cut using cut-off tools and gas saws. Angle grinders are also popular. Nevertheless, accidents involving these instruments are a primary source of injuries to workers.
Hydraulic bar cutters can be used to avoid flying sparks, exploding wheels and cut-off wheels. This cutting method is time-saving and increases production by eliminating unnecessary precautions.
Dremel
A Dremel will work fine for cutting through rebar. Choosing one designed specifically for metal cutting is your best best.
You will need to replace the blade of this tool frequently. A Dremel is probably not the best tool when working with heavier objects. This power tool can be a great choice if you are looking for something lightweight and inexpensive to do a quick task.
