A rebar tying tool, also known as a reinforcement bar tying tool, is a power tool used to fasten rebar together during construction. The best rebar tying tool will be lightweight, easy to control, and will be easy to service and maintain.
Reinforcing steel bars, or rebar, are very strong steel strips that are used in the construction of many concrete buildings, bridges, and other structures. These bars provide structural support, and our modern world couldn’t be made without them. It’s important to securely link each piece of rebar together, as this provides essential structural rigidity (Source).
Rebar tying tools make this process a lot easier and faster than tying the rebar junctions by hand, and time is money. Rebar tying machines are helpful tools that are placed at the intersection of pieces of rebar. When the trigger is pressed, the tool will automatically feed just enough wire around the rebar intersection. The tool will then automatically twist and cut the wire.
With so many options out there, and rebar tying being such an important part of the construction process, it can be hard to make a purchasing decision. Before you buy a rebar tying tool, consider the operating speed, weight, and battery life, among other top factors (Source).
In this review, we will take a detailed look at all the top-rated tying tools. All of the rebar tying tools in this article will join rebar quickly and effectively, whether you are building an addition onto your home, or working on a job site.

Whether electric or manual, reinforcement bar (rebar) tying tools are used to tie rebars together or electrical conduits to reinforcement bars during construction. Reinforcement bars are often tied together using binding wire.
The best rebar tiers are specifically designed to tighten the binding wire around the reinforcement bars in order to hold them together more securely. You will find the electric models, whether corded or cordless, to be faster, ergonomic, more versatile and comparatively easier to use.
The right tool for whichever construction application should also be designed to reduce fatigue to the user. Although rebar tying tools are primarily designed to wrap the wire around the rebars and twist it to tie them together, various models differ from each other.
How Does a Rebar Tying Tool Work?
Rebar tying machines use a lithium-ion battery and are used where two rebar rods meet. At the click of the trigger, this tool then automatically feeds the needed wire around the rebar rods, twisting and cutting it. This process is done at great speed and with a firm wrap of the rebars.

Factors to Consider Before Buying a Rebar Tying Tool
Having to tie rebars manually is a demanding task that often takes a lot of time. First, you need to tie wire around a rebar length, determining the desired position before twisting the wire via pliers. Not only does this result in fatigue, but it may also lead to injuries.
In order to buy the best electric rebar tying tool and avoid such, here are some of the main considerations you need to make:
Type of Rebar Tying Tool
Depending on the type of construction project you are undertaking, you will be required to make an assortment of rebar tie knots. To begin with, you need to choose between the best manual rebar tying tools and the modern battery-powered rebar tying tools. Again, you also need to check the type of tying ‘knot’ the model is capable of making.
Additionally, there are several other rebar tying ‘knot’ types you should consider:
- Snap Tie
This is one of the commonly used rebar ‘knot’ types to securely wrap rebars together. A snap tie wraps the binding wire once around a rebar joint, twisting it tight. The tie is then snapped off at the long end. This type of tie is best suited for horizontal structures, such as concrete foundations.
- Wrap and Snap Tie
This tie is commonly used to secure horizontal rebar sections to vertical supports. To tie this knot, a wire is wrapped around the different sections, tied and then the excess wire is snapped off. The wrap and snap tie may be done manually, but a high-powered wire tie tool will make the complex task easier and faster.
- Saddle Tie
Also referred to as the “U” tie, the saddle tie is a bit complicated than the snap tie. Similar to a square knot, a saddle tie creates a diagonal bind across different rebar sections. Owing to its complexity, this tie is best achieved using an electric rebar tying tool.
- Figure Eight Tie
The figure-eight is incredibly secure and is often used to secure vertical reinforcements. In most cases, the figure-eight needs to be carried out at awkward angles hence the need to use the right battery-powered rebar tying tool.
In most construction sites, you will be required to make many ties per unit time in order to accomplish the project within the schedule. As such, you need a tool that is relatively fast at tying. The speed offered by your preferred rebar tying tool is a key consideration, in this case.
Different tying tool models offer different speed levels and are expressed in terms of the time it takes the tool to accomplish a single tie. Most of the high-end rebar tying tools will take about 0.8 seconds to make a single rebar tie.
However, the speed will also depend on the type of tie you are making. The more complex rebar ties generally take longer than the simpler ones.
For enhanced portability, most of the leading rebar tier models are powered by rechargeable batteries. Such models are also easier to use as you will not have to worry about a power cable getting entangled as you work. However, you need to check the battery capacity of the unit to ensure that it meets your needs.
To begin with, you need to check the number of ties the unit can complete on a single charge. For instance, the best Makita rebar tying tools may be used about 6,000 times per charge. Again, you also need to pay attention to the battery voltage.
You may also go for units that come with two interchangeable batteries or that features fast charging capabilities. This will help reduce downtimes.
Several rebar ties need to be carried out at different angles and in a myriad of situations. The tool you get should allow for easy customization to suit an array of applications. For instance, the tool should be easy to bend at various angles.
In this regard, it is advisable to get a model that allows you to adjust the tension as well as the angle of the bar to fit the requirements of the project at hand.
The tool should also allow you to set the tying strength to your preferred level. Again, you need to ensure that the tool may be used with different wire and rebar sizes.
In order to combat fatigue and reduce associated injuries, you should go for a tying too that features an intuitive design and is comfortable to use. For instance, the rebar tying tool you choose should be lightweight and relatively easy to control in operation. Models with a second handle are known to offer better control in various applications.
Again, you should consider the grip size and shape offered by the tool. The tool should offer a confident grip that is comfortable for the hands, even with extended use. You may also need to check the trigger design and positioning on the tool.
How to Use a Power Rebar Tying Tool
Using the rebar tying tools by the leading brands is rather easy. In essence, you only need to position the tool next to the pieces that need to be bonded together and press the trigger.
Whether using the tool to lash together rebar in flatwork or standing wall work for reinforcement, the operation of the tool is more or less the same.
First, you need to calibrate the tool to the right tying tension and set it to single or continuous tying mode, depending on the type of tie you need to make.
Check to see whether the battery is charged and turn it on. Now position the steel rebar pieces in the required positions. Hold the tool firmly in your hand(s) and position it next to where you would like to make the bond and pull the trigger.
In some projects, you may be required to hold the rebar tie tool with one hand while using the other one to hold the rebar pieces together.
Ready to Use a Rebar Tying Tool in Your Next Project?
Tying rebars together is one of the most demanding tasks in any construction site especially if it has to be carried out manually. In addition to fatigue, manual rebar tying has been proven to cause an assortment of musculoskeletal injuries.
This is why you need to get an easy-to-use, powerful, customizable and efficient power rebar tie tool. Just like the five units reviewed above, your preferred model needs to be capable of accomplishing different tying tasks.
