Best electric metal shears for cutting sheet metal and roofing

Best corded electric metal shears

Most, if not all, of the commodities we make use of to cut metal today, have their origins from centuries back when metal sheets are cut without power tools.

Many of the power tools that we’ve grown accustomed to and easily carry around are the product of years’ worth of development of once immobile and primitively complex machinery.

Electric metal shears, or basically mechanical scissors for metal, if you want to term it operatively, started in the 14th century as big industrial engines that cut metal through bending or shearing.

Fast forward to today, and the same concept is still used, albeit made easier and in a more portable form thanks to the advancements in science and technology.

Nowadays, it’s very unlikely that you’ll find anyone who works with power tools to not have an electric shear.

Electric shears are some of the most common tools for cutting sheet metal as well as being among the most common ones used in general metalworks. 

Electric shears are usable by both the skilled and unskilled; meaning just about anyone can use them, be they professional or just your standard stay-at-home folk.

These tools are a staple for any person who works with metal as they are key in aiding light fabrication which is a staple in the practice and business operations of local carpenters, roofers, and hardware store owners.

Electric shears are powerful as they allow you to cut straight through steel like a hot knife through butter.

They are versatile, simple, and don’t require too much maintenance to keep operating in peak condition.

There are corded variants for bigger jobs, as well as cordless ones that are just perfect for workers who are constantly on the go.

In this article, we’ll be guiding you through what we’ve ranked are the best shears in terms of performance, specifications, and price. 

Features to consider

• Power. Power as in how much grunt your tool is capable of delivering. Usually measured in Amperes (Amps), the general rule is the higher the amps, the more power is at your disposal. Though it’s not necessarily the deciding factor that says how good the tool is at cutting, a 5-amp metal shear definitely operates with more raw force than a 4-amp one.
• Ergonomics. Ergonomics refers to the size, weight, and how well and how comfortably the tool handles in hand. Keep in mind that this is a power tool and though it can make work much faster, prolonged use can still cause fatigue. It’s important to consider this factor and pick a tool that you’d have an easy time with.
• Cutting capacity. In metalwork, a Gauge (GA) determines the metal’s thickness. When factoring in cutting capacity, bear in mind the majority of materials that you’ll be commonly working with if they are either light- or heavy-gauge. Usually marked descending in order of thickness. (E.G 22GA is thinner than 14GA that is thicker).
• Durability. Sheet metal shears should last a lifetime with proper care so make sure to get a tool that is built to last your workload. There are cheaper options for DIY, but purchasing a dedicated tool should be an investment.
• Manufacturer. Coupled with durability is often the brand name; a trusted and well-known manufacturer always produces superior quality products. Having an idea of a manufacturer’s background and track record will save you time and precious resources as you’ll already know the quality of the tool you’re about to get.

You’ll definitely notice the Makita XSJ01T not only for its noteworthy price tag but for its premium specifications. It is built with a 4-pole motor, allowing it to have an even faster cutting speed of up to 3000 strokes per minute.

The double-cut design enables it to cut through 18 GA mild steel and 20 GA stainless steel effortlessly.

Weighing at about 5.3 pounds, it’s made even more comfortable to maneuver with its 360-degree rotating swivel head and rubberized grip handle.

If you’re on a slightly tighter budget, the Ryobi P591 does nicely for most cutting jobs.

Its plastic body makes it the lightest model on the list, weighing only 3.4 pounds. These shears can handle cutting through 18 GA metal as well as other medium-duty tasks without much fuss.

However, it does struggle with cutting certain materials like R-panels and standing seam roofing.

Fortunately, this won’t really be a problem if you only need to work on flat sheets of metal.

Although it’s not as portable as the other models on this list, the Milwaukee 6852-20 surely packs a lot of power to make up for its lack of mobility.

Its body is made out of polycarbonate, making it incredibly durable and hard-wearing.

This Milwaukee metal shear can reach a cutting speed of up to 2500 strokes per minute on its trigger speed control, allowing for a smooth cutting experience on 18 GA steel.

It is a double-cut shear designed with a 6.8-amp motor, ergonomic grip, and 10-foot runner cord.

These attributes, along with the 360-degree rotating swivel head, allow for comfortable and easy handling.

It’s understandable why some would initially be confused between these tools since their physical designs are very similar.

Nibblers get their name because of how they raze or “chew” through a material. They are better for cutting out tight curves as well as more elaborate shapes and patterns without distorting the material.

On the other hand, metal shears are better for heavy-duty tasks and can handle cutting thicker sheets of metal while not creating a lot of waste material.

Your to-do list with electric metal shears

• Always wear proper safety gloves while working.
• Clean your workstation since small metal pieces and shavings can be hazardous if disposed of incorrectly.
• Operate in a well-lit area so you can clearly see what you’re doing at all times.

Your not-to-do list with electric metal shears

• Avoid leaving your shears unlocked or plugged in when not in use.
• Don’t rush. Work at a steady pace to minimize errors and create clean finishes.

In summary, the DeWalt 20V DCS496B ticks all the boxes of what an electric metal shear should be. It offers great maneuverability at a reasonable price while being able to handle several cutting tasks with ease.

The Makita XSJ01T may seem intimidating because of its price but is sure to impress you with its quality performance and unmatched cutting speed.

Although it may be difficult to use with certain materials, the Ryobi P591 still gives commendable results for an affordable price.

Lastly, the Milwaukee 6852-20 is definitely a model you should check out if you’re looking for Milwaukee metal shears with a lot of power and a heavy-duty build that is sure to last for years.
