From large-scale roofing projects to the design of high-end metal objects and crafts, metalworking continues to attract many people, both as a hobby and as a career. The field requires innovative, state-of-the-art machinery that facilitates and simplifies the metalworking process. Metal shears are at the heart of this process.
Shearing is one of the oldest processes in metalworking, but electric shears have made great strides compared to tabletop shears. Metal shears are powerful and useful tools designed to cut large plates in straight lines with high precision. Equipped with small, sharp shears, they work like scissors to cut thick sheet metal accurately and smoothly.
Electric shears come in a variety of diameters and motor powers, as well as types such as single- or double-edged shears. Depending on the type of work and the surface to be worked on, you can find the right one. Take a look at this list of the best electric shears for 2024 and improve your workshop the right way.
Best Metal Shears For Metal Roofing
Cardboard and Nibblers
I know what you are thinking, “What about cardboard? How can I cut it with scissors?”. And that is a very good question.
The problem with cutting corrugated board is that it is not flat. To cut it with shears, you have to cut it up and down or at right angles. This makes no sense. This is where the cutter comes in.
Cutters generally employ a punching mechanism, which is literally a tool that punches through metal by projecting the blade at a fixed position in a straight line. As a result, bolt cutters do not have uniform cutting ability. When using mordants, one should be aware of the semicircular chips that the tool makes when cutting.
These metal chips are painfully sharp and often scratch floors and other surfaces they come in contact with. It is important to try to keep chips within the work area whenever possible. Many users use magnets to keep their workspace organized.

Best Metal Shears For Metal Roofing | Ultimate Buying Guide 2024
Intended Use
All electric shears are not the same in terms of versatility. While some can perform a variety of tasks and work with multiple materials, some shears are only suitable for certain tasks and materials. For example, a construction worker doing roofing will need metal shears that are better suited for the job, as opposed to those that are specialized for auto repair. Before purchasing, make sure you know what you need the shears for.
Types
There are two main types of electric shears: corded and cordless. Each has its own advantages and disadvantages, so an inspection is necessary to determine which is best for you.
Corded Electric Pruning Shears
Corded metal shears, like many other tools used in the workshop, must be connected to a power source to function. They typically have a 4- to 6-amp motor and require an average current of 110 to 120 volts. Because of their effective cutting capacity, they excel at large, demanding jobs. Wire shears can effectively cut stainless steel sheets averaging 18-22 ga.
Cordless Electric Shears
Lighter and more convenient versions of electric shears are battery shears, which are rechargeable and interchangeable and work differently. They require the same amount of power as corded models, but battery-powered metal shears use energy more efficiently. When cutting thick sheet metal, these versions seem to fall short. Standard cordless electric shears can cut materials up to 14 ga. thick, making them ideal for beginners and DIYers.
Gauge
Like power, another factor that determines the performance of metal shears is gauge. The gauge represents the ability of the electric shears to cut sheet metal of a certain thickness. The thickness of sheet metal that can be cut with electric shears is called the gauge.
The most common gauges of electric shears range from 22GA to 14GA, with the latter being considered the higher end of the range. Higher gauge models can only be used with thinner sheets. Since each metal has a different gauge rating, the rating is indicated next to each metal type in the product description.
Blade Type
In addition to the motor, the shearing blade determines the sharpness and life of the shear. Because it touches the material, the blade must be strong enough to last a long time. Blades can be replaced, but be sure to maximize the performance of the blades installed.
In addition to strength and durability, the blade must be perfectly sharp to cut metal more smoothly and finely. Also, pay attention to the formation of the blades. The number and position of the blades determine the smoothness and uniformity of the metal cut. It also helps to carve shapes and make curved cuts in sheet metal.
Power Supplies
Choose from corded, cordless, and pneumatic units, as well as accessories for use with your current impact wrench. Corded units are suitable for long hours of use, while cordless units are more portable. Pneumatic units are suitable for heavy duty work, while accessories are suitable for light to medium duty work.
Blade hardness and durability
The hardness of a knife determines its durability and ability to cut different types of metals. Steel hardness is measured on the Rockwell HRC scale. Typically, knives are between HRC 56 and 65.
As the hardness approaches 65, they are able to cut harder materials, such as thicker steels. A surcharge is also paid for these hard blades.
When choosing scissors, it is important to consider the type of metal to be cut. For softer metals, such as thin tin sheets, a hardness of close to 65 may not be necessary. However, if you are cutting stainless steel or other hard metals, you will need hard shears.
Specialized scissors
There are several types of specialized scissors for special situations.
Pelican scissors, for example, have a slightly offset handle and long blades to make long, straight cuts. The offset keeps the hand away from the material. Because of the long blade and offset handle, it is difficult to control the cutting angle, making them unsuitable for curves.
Circle cutters are gently curved and usually have smooth blades to produce a uniform, constant radius. These curve cutters are ideal for carving fine eaves.
Gauge or steel thickness
In general, most metal shears can cut 18-20 mild steel, but the value may vary depending on the design of the unit. If you are cutting thicker materials, you may want to choose metal shears manufactured for thickness.
Ease of use
Is the shears ergonomic when you hold them? Do they not slip or are they easy to grip? Metal shears should be comfortable with minimal vibration. The swivel feature also helps when cutting curves and corners. Light and sturdy metal shears are also easier to carry.
Speed
Know the SPM speed of the metal shears and whether it is variable or single speed. If you are working with different materials, you may want to choose a unit with a variable speed because if the material is too soft, it can be accidentally deformed.

- Manual sheet metal shears: These are handheld shears that use a lever action to cut through sheet metal. They are suitable for cutting thin sheets of metal and for small-scale projects.
- Foot-operated sheet metal shears: These are larger shears that use a foot pedal to activate the cutting blade. They are suitable for cutting thicker sheets of metal and for larger-scale projects.
- Mechanical shears: These are powered shears that use a motor and hydraulic system to cut through sheet metal. They are suitable for cutting thick sheets of metal and for industrial-scale projects.
- Laser cutters: These are high-tech machines that use a laser beam to cut through sheet metal. They are precise and can be used to create intricate designs, but they are also expensive and require specialized training to operate.
When choosing a sheet metal shear, it is important to consider the type and thickness of the metal being cut, the size and scale of the project, and the level of precision required.
How thick of metal can a shear cut?
The thickness of metal that a shear can cut depends on the type and capacity of the shear. Here are some general guidelines:
- Manual sheet metal shears: These are typically designed to cut thin sheets of metal up to 16 gauge or 1.6 mm thick.
- Foot-operated sheet metal shears: These can typically cut thicker sheets of metal up to 14 gauge or 2.0 mm thick.
- Mechanical shears: These can cut thicker sheets of metal up to 1/2 inch or 12.7 mm thick, depending on the capacity of the machine.
- Laser cutters: These can cut through a range of thicknesses, from thin sheets up to several inches thick, depending on the power of the laser and the type of metal being cut.
It's important to note that the maximum thickness of metal that a shear can cut will also depend on the type of metal being cut, the hardness and strength of the material, and the blade and cutting edge quality. It's always best to consult the manufacturer's guidelines and specifications to determine the appropriate capacity for a particular shear.
What is the difference between nibbler and shear?
A nibbler and a shear are both tools used to cut sheet metal, but they work in different ways and are designed for different types of cuts.
A shear is a tool that uses a straight blade to make straight cuts in sheet metal. The blade is typically mounted on a lever or hydraulic system, and the sheet metal is positioned between the blade and a flat surface, called the anvil. When the blade is pressed down, it cuts through the metal along a straight line.
A nibbler, on the other hand, is a tool that uses a punch-and-die system to make curved or irregular cuts in sheet metal. The punch and die are mounted on the nibbler, and the sheet metal is positioned between them. When the nibbler is activated, the punch moves up and down, punching small notches in the metal, and the die cuts through the notches, creating a curved or irregular cut.
The main difference between a nibbler and a shear is the type of cut they can make. A shear is designed for straight cuts, while a nibbler is designed for curved or irregular cuts. Shears are typically used for cutting large sheets of metal into smaller pieces, while nibblers are used for cutting complex shapes and patterns.
Another difference is that shears can cut through thicker sheets of metal than nibblers. Shears can cut through metal up to several millimeters thick, while nibblers are best suited for cutting thin sheets of metal up to a few millimeters thick.
Overall, the choice between a nibbler and a shear will depend on the type of cut needed and the thickness of the metal being cut.
What blade do you use to cut metal roofing?
The blade you use to cut metal roofing will depend on the type of roofing material you are working with and the tool you are using to cut it. Here are some common types of blades used for cutting metal roofing:
- Circular saw blade: A circular saw blade with carbide teeth is commonly used to cut through metal roofing sheets. These blades are designed to make straight cuts and are suitable for cutting through thinner gauge metal roofing.
- Jigsaw blade: A jigsaw blade with tungsten carbide teeth is another option for cutting metal roofing sheets. Jigsaw blades are ideal for making curved or irregular cuts, such as around vents or pipes.
- Reciprocating saw blade: A reciprocating saw blade with carbide or bi-metal teeth can be used for cutting thicker gauge metal roofing, such as corrugated metal. Reciprocating saws are ideal for cutting through thicker materials quickly and efficiently.
- Nibbler attachment: A nibbler attachment on a power drill can also be used to cut through metal roofing. Nibblers are ideal for cutting complex shapes and patterns and are suitable for thinner gauge metal roofing.
When selecting a blade for cutting metal roofing, it's important to choose a blade that is designed for the specific material and thickness of the roofing. Using the wrong blade or tool can result in damage to the roofing material or the tool itself, as well as potentially hazardous conditions.
What are the three types of shears?
Shears are cutting tools designed for cutting various materials such as fabric, paper, and hair. There are several types of shears, but here are three common types:
- Dressmaker Shears: Also known as sewing shears, dressmaker shears are designed for cutting fabric. They are typically longer than other types of shears, with blades that range from 7-12 inches in length. The blades are usually angled and have a slight curve, which allows for smooth and accurate cuts through the fabric.
- Barber Shears: Barber shears, also known as hairdressing or hair-cutting shears, are designed for cutting hair. They typically have a shorter blade length, ranging from 4.5-7 inches, and have a straight or slightly curved blade. Barber shears also have a different handle design that allows for precise control and comfort when cutting hair.
- Kitchen Shears: Kitchen shears are designed for cutting food, such as meat, poultry, and vegetables. They typically have a serrated or straight blade and are often designed to come apart for easy cleaning. Some kitchen shears also have additional features such as bottle openers and nutcrackers built into the handle.
Which tool is used for extremely thick sheet metal?
For extremely thick sheet metal, a tool called a plasma cutter is often used. Plasma cutters use an electric arc and high-velocity jet of ionized gas (plasma) to melt and cut through metal. The plasma cutter can be used to cut through a variety of metals, including steel, aluminum, and copper, and can typically cut through metals that are up to 6 inches thick or more.
Plasma cutters can be handheld or mounted on a CNC (computer numerical control) machine for precision cutting. They are commonly used in industrial and fabrication settings, such as metalworking shops, automotive repair shops, and shipyards. Due to the high temperatures involved in the cutting process, plasma cutters should only be used by experienced professionals who have been trained in their safe and proper use.
What metal has the highest shear strength?
Among commonly used metals, tungsten has the highest shear strength. Tungsten is a rare and dense metal with a very high melting point, which makes it an ideal material for high-temperature applications where strength and durability are important. Its high shear strength is due to its strong metallic bonding, which allows it to withstand high stresses and resist deformation.
The exact value of tungsten's shear strength depends on various factors such as its purity, crystal structure, and processing method. However, it typically has a shear strength of around 343 megapascals (MPa) at room temperature, which is significantly higher than other commonly used metals such as steel, aluminum, and titanium.
It's worth noting that there are other materials, such as ceramics and composites, that can have even higher shear strength than tungsten. However, these materials are generally not as widely used in industrial and structural applications as metals are.
Is Titanium good for shears?
Titanium is a strong and lightweight metal that has a high strength-to-weight ratio and excellent corrosion resistance. Due to its properties, titanium can be a good choice for shears, particularly for applications where strength and durability are important.
Titanium shears can be particularly useful in situations where the tool may be exposed to moisture, chemicals, or other corrosive substances. The corrosion resistance of titanium means that the shears will be less likely to rust or degrade over time, even with frequent use.
In addition, titanium is relatively easy to work with, which makes it a good material for precision cutting tools like shears. However, titanium is also a relatively expensive material compared to other metals, which may affect the cost of the shears.
Overall, while titanium shears may be a good choice for some applications, the specific properties and design of the shears will ultimately determine their performance and suitability for a particular use case.
What is the difference between shearing and cutting?
Shearing and cutting are both processes that involve separating materials into smaller pieces, but they differ in the way that the material is cut.
Cutting involves using a blade or tool to physically separate the material by applying force to it. This process can be used to cut a wide range of materials, from paper and fabric to metal and wood. In cutting, the blade moves through the material, causing it to deform and eventually separate along the cut line.
Shearing, on the other hand, involves using two blades or tools to push and pull the material in opposite directions, causing it to break along a predetermined line. Shearing is typically used to cut sheet metal and other thin materials. The blades in a shear move past each other to create a cut, with one blade holding the material in place while the other blade moves against it. This results in a clean, straight cut without deformities or distortions.
In summary, cutting involves the blade moving through the material to make the cut, while shearing involves the blades pushing and pulling the material to cause it to break along a line. Both processes can be used to cut a variety of materials, but the specific method chosen will depend on the material being cut and the desired outcome.
Where would nibblers have an advantage over shears?
Nibblers are handheld cutting tools that are used to cut sheet metal, plastics, and other thin materials. They have a cutting head with a small, reciprocating punch and die that work together to punch out small, precise sections of material. Nibblers have several advantages over shears in certain applications, including:
- Cutting curves and irregular shapes: Nibblers can cut complex curves and irregular shapes in sheet metal and other thin materials with ease. The small punch and die can be maneuvered to follow the desired cutting path, resulting in a clean and precise cut.
- Cutting in tight spaces: Nibblers can cut in tight spaces where shears would not fit. The small cutting head of a nibbler can fit into small spaces and cut around obstructions, allowing for more flexibility and precision in cutting.
- Minimal distortion: Nibblers produce minimal distortion of the material being cut. Because the cutting action is punching out small sections of material, there is very little deformation or bending of the material, which can be important in some applications where precise dimensions and shapes are required.
In summary, nibblers have an advantage over shears in applications that require cutting of curves, tight spaces, and minimal distortion of the material being cut. However, shears may be more suitable for cutting straight lines or thicker materials where nibblers may struggle. The choice between a nibbler and shears will depend on the specific requirements of the application.
