Best Conduit Reamer

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:

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.

DeWalt is an American veteran tool maker. It is one of the most respected brands in the market today and makes some exclusive tools for electricians.

For many workmen, DeWalt is the manufacturer of choice.

The DeWalt DWA2600IR is an excellent conduit reamer.

The conduit reamer is Impact Ready, as you would have noticed from the name of the product itself. This means that you can use it for high-torque impact drivers, right out of the box, without any configurations.

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.

Personally, I think Klein Tools conduit reamers are perhaps some of the best in the market, albeit with a higher price tag than the average.

The Klein Tools 85091 is a conduit fitting reamer drill head. It is a great choice for de-burring electrical metallic tubing.

In fact, it can ream the EMT, both internally and externally, at the same time. This makes it a very productive tool and will let you save a chunk of your time, which would be wasted in working with conduit and mounting boxes.

Moreover, you would also be safe from any wear and tear to your arm, since the tool does all the work for you. Functionality wise, it can work with reams of various sizes (1/2”, 3/4” and 1”) and can install fittings within seconds.

The tool can easily be set on a power drill chuck or quick release adapters, without requiring any specific expertise. Compared to its previous generation, the 85091 has an improved bit retention and comes with a replaceable reaming blade.

With this tool, you can easily cut conduit and install anchors without putting stress on your arms or changing tools.  It might seem like a luxury to some electricians, but given my experience with it, I will frankly state that if you are on a project with several conduit jobs, then you are going to need this tool.

Like all Klein Tools, this one is also backed with a solid warranty for any manufacturing defects or functionality problems.


  • Various reams
  • Quick fitting installation
  • Fits in drills
  • Good bit retention
  • Replaceable blade
  • Klein warranty


  • Magnetic tip doesn’t hold screws well


Greenlee Conduit Reaming Screwdriver

Greenlee is one of my favorite manufacturer of electrician tools. It is an American company that has been manufacturing for over two centuries, which is a testament to its quality and reliability.

The Greenlee 9753-11C is a conduit reaming screwdriver. Aesthetics wise it looks very similar to the Klein Tools reaming screwdriver we saw at the top of this list, with a green and black color scheme.

The tool is pretty good in its reaming properties and can handle both the inner and outer diameters at the same time. This makes it easier to do installations and prevents any risk of wire insulation damages. The flat blade is hooded for protection and is a great driver for EMT fittings.

The handle has appropriate marking along the side for identification. Apart from the functions, the company has also taken ergonomics of the tool in note.

It comes with a cushion grip for a comfortable grip, that itself promotes torque. Do not that the tool is not insulated and hence should not be used near live current by electricians.

Like all Greenlee conduit screwdrivers, this one also comes with a life time warranty, which reflects the manufacturer’s confidence in the making and performance of its product.


  • Handle marked
  • Hardened blade
  • Hooded, flat tip driver

The tool does not look the most visually pleasing nor has the best finishing. However, looks aside, if you are concerned about its performance at a job site, you will be more than satisfied.

The Ideal 35-083 Twist-A-Nut is a good choice for conduit de-burring. The tool has been manufactured in USA and comes in an attractive yellow / black color scheme.
