Well, these questions won’t be bothering you anymore, as we are here to guide you towards the most valued products made just for your satisfaction.


Conduit Bender buying guide

Just like any other product, purchasing a conduit bender may seem easy but does require some extra knowledge of what to expect and what to avoid. Keeping that in mind, we have encountered and shared a bunch of factors that you need to consider before making your next move. The days of asking others for advice will be finally over once you go through this section.


Build Material

When it comes to conduit benders, the material used in it matters more than anything else. The manufacturers offer various elements, such as steel, aluminum, etc. Although steel provides excellent power, it adds some weight to the tool as well. So, make sure you look for a solid aluminum build, which will not only offer strength but also give the ease of carrying.

Weight and Portability

Benders come in different sizes and shapes due to specialized uses. As a result, you will find a variety of tools in the market, having a variety of weights. Conduit benders are found to be weighing between 1 to 9 pounds! Yet, you can’t throw away one just on the basis of weight since the weight itself has some basis too.

Be aware of the fact that you may face quite a hassle in carrying heavy benders from time to time, and thus, it will be wise to go for the lightweight ones if you fall in this category users. But since it’s often about bending hard metals the tube holding portion should be robust and rigid. This implies that, if bending conduit after conduit is what you’re longing for, weight should not be the strictest defining factor

Size of the Foot Pedal

You will find it easier to bend tubes using broader foot pedals than the thinner ones. So, try to make sure that the conduit bender you purchase features a foot pedal, which is wide enough to provide the necessary comfort.

Presence of Handle

Although many companies provide the required handle along with the head of a bender, some of them don’t. Whether you want to put the additional effort into finding the matching handle or not depends on you. But as the extra hassle will disappear with a complete package of head and handles, taking such a conduit bender is therefore recommended. But keep a balance of your budget.

Offered Tube Sizes

Benders, in general, feature one or two sizes of tubes that can be bent using them. Such dimensions include the ¾ inches EMT and ½ inches rigid tubes. These are the radius measures your conduit bender has to ensure. You may also go for the unique tools that allow all the sizes of tubes.


A way of identifying top-class conduit benders is to check the number and quality of cast-in markings on their body. These markings include degree values and help you to bend your tubes in the desired shape. Make sure you check the presence of the markings if you want to work faster and smoother.

Degree Range

You may need different amounts of bend, depending on the type of project. So, consider purchasing a bender that offers a wide range of angles. Also, go for the ones that are capable of bending from 10 to 90 degrees at least. Some manufacturers also provide a capacity of 180 degrees, and you may get one if your projects require such an angle of bending.


The more ergonomic the design gets, the more enjoyable your experience of bending tubes become. You should not purchase the poorly designed ones because of the difficulty they bring along. Always check if the designs are perfect and if they provide a good experience of working.


There are a variety of bending techniques for different purposes, such as saddle bends, stub-ups, offsets, etc. You may consider picking a bender that is specialized in one or two types of bending, depending on your requirements. Looking for an all in one is not the best option every time.


Companies that are concerned about the satisfaction of their users provide a sufficient quantity of warranty. You never know whether the unit you receive will be completely okay or not. Hence, it is better to grab a tool that comes with a good warranty.
