A conduit reamer will be a commercial electrician’s best tool, especially when thousands of feet of conduit needs to be ran.

Some tools that compliment the pipe reamer are:

• Fish Tape
• Electrical Gloves
• Torpedo Level 

These are some of the primary tools you will use when installing and EMT conduit and THHN wire.

Modern conduit reamers are quite advanced and productive.

They come in manual and automatic versions, either of them being very effective depending on the size of the job at hand.

Buying a conduit reaming tool is an investment that, if made correctly, will last you for several years.

However, how should you go about buying a conduit reamer and which ones are the best in the market at the moment? If you go on a look out yourself, you may be boggled by the choices you have, both of high and low quality. Of course, you want to avoid the latter.

To help you with this, I have curated this article within which I am going to discuss some of the top conduit reamers available for purchase and how to make sure one of them is perfect for your requirements.

Why Do You Need A Conduit Reamer

Perhaps you are an old school electrician and are wondering why you would need an additional tool in your arsenal.

Many years ago, the way that workmen were taught to ream conduit was to strip the ends off the channel locks, insert them into the pipe, then twist it. Then take the other end to go on the outside and clean it. Then check it for any burrs. After assembling the fitting, the workmen would have to get a screw driver and then tighten the fitting, before their conduit was ready to go.

Now with the modern conduit reamers, this job is much more efficient. After cutting the pipe, just take the conduit reamer into the pipe and ream it. After that, just take your fitting and screw it with the add-on that is already on the conduit reamer.

How I Picked The Best Conduit Reamers For My List

Picking out the best products from a pool of options can require experience, knowledge and a lot of time. Thankfully, you do not have to go through this process as I have done the hard work for you.

To make my list full of quality and unbiased products, I first shortlisted the conduit reamers which had a high customer feedback score on the top online marketplaces. After that I eliminated the products which had limited features, but were charging the same price as an advanced tool. Lastly, I cleared my list off any products that did not come with a warranty.

The properties I looked for in my conduit reamers were the sizes they supported, the quickness with which they did their job and their durability. These are the most important features in my opinion and weighed in largely during my product selection and elimination from my short list.

Klein Tools Conduit Reamer Drill Head

If you are reading this article from the start, you would know that we have already covered one Klein Tools product. Here we have another one.
