The Best Power Shears to Crop Metal Sheets SeamlesslyLast updated: 17 Aug 2022
From large-scale roofing projects to designing classy metalware and artifacts, metalworking continues to captivate many as both a hobby and career. The ever-growing industry widens the scope for innovative and state-of-the-art machinery that facilitates and streamlines the metal fabrication process. Metal shears are at the root of these innovations.
Even though shearing is among the oldest processes involved in metalworking, power shears come as a massive upgrade from bench-type shears. Metal shears are a powerful, handy tool designed to perform straight and high-precision cuts on large metal sheets. They feature sharp tiny clippers that work in a scissors-like mechanism severing through thick metal sheets accurately and smoothly.
Besides the different types, such as single-cut shears (unishears) and double-cut shears, power shears vary in gauge rating and motor power. Finding the right one depends on the type of work or surface you are working on. Check out this informative list of the finest power shears of 2022 to upgrade your workshop the right way.Show contents
Buyer’s Guide: Discovering Your Ideal Power Shears
Metal shears are not some recent invention. Though unpowered, it’s one of the oldest tools, being used to cut and shape metal sheets for centuries. From simple manual versions to advanced handheld power shears, Metal shears come in various types and versions. In case you have been associated with the metalworking industry for some years now, you’d definitely have the old manual shears lying somewhere in your workshop.
With the metalworking industry on the rise – in terms of industrial or domestic scale (mostly handicraft) – it’s high time you equip yourself with advanced tools with power shears at the top of your list. Whether you are simply assembling the metal roofing or having a passion for entering the meal handicraft and metalware industry, the need for specialized and efficient power shear remains vital from start to end.
What to Consider When Buying Power Shears?
To get power shears that are efficient, durable, and versatile to use, you need to consider the following factors:
Power shears are not one-size-fits-all in terms of versatility. While some can perform various tasks and are compatible with multiple materials, other power shears are only good for specific jobs and materials. For instance, construction workers who are associated with roofing will need a different pair of metal shears than the ones who specialize in automotive repair and will require one better suited to their needs. Make sure you determine what you need power shears for before purchasing.
Electric power shears come in two main types: corded and cordless. Considering each has its own set of pros and cons, inspect to determine which one would work best for you.
- Corded power shears
Like many other powered tools in your workshop, corded metal shears must be plugged into a power source to operate. They usually feature a 4–6-amp power motor that requires 110–120 volts of current on average. They specialize in taking up extensive and pressure-inducive tasks with their effective cutting capability. Corded power shears can effectively cut through a stainless-steel sheet, averaging 18–22 GA.
- Cordless power shears
A more lightweight and convenient version of power shears, cordless shears operate distinctively through either rechargeable or replaceable batteries. Even though they require just as much power as their corded counterparts, cordless metal shears use the power more efficiently. With cutting through thick metal sheets, these versions appear lacking. A standard pair of cordless power shears can cut materials up to 14 GA in thickness, making them ideal for beginners and DIYers.
Like power, gauge rating is another factor used to determine the performance of a metal shear. Gauge rating describes the ability of power shears to cut through a metal sheet of a particular thickness. The thickest metal sheet power shears slice through is identified as its gauge rating.
The gauge rating of most power shears ranges between 22 GA to 14 GA, with the latter being the superior grade. Models with a higher gauge value can only work with thinner metal sheets. Since the power rating of each metal varies, the rating is marked alongside each metal type in the product description.
Apart from the motor, the power shear blade is one factor determining the cutting power and longevity of a power shear. Since they are the ones in contact with the material, blades should be sturdy enough to last longer. Even though blades are replaceable, try to make the best out of the ones installed.
Besides the strength and durability, a blade should be intricately sharp for a smoother and finer metal cutting experience. Pay attention to the blade formation as well. The number of blades and their positioning determines the smoothness and uniformity of sliced metal sheets. It also helps in etching shapes or making curved cutting on the sheet.
Double-cut Shears Versus Single-cut or Unishears: Which One Should You Choose?
Beginners often get confused between double-cut and single-cut power shears, mistaking them for the number of blades. Read on to learn about the differences between differently cut shears:
Like your regular scissors, single-cut shears or unishears feature a moving blade against a fixed blade attached to the shear head. The moving blade cuts the metal sheet as it slides against its surface onto the fixed blade. Although unishears do not produce any waste or dust when cutting, they may distort or bend the edges of the metal sheet.
Double-cut shears have two distinctive cutters that move against each other to slice through a metal sheet. Unlike its counterpart, a double-cut shear leaves behind residue but keeps the uniformity of the metal structure from any distortions.
Important Tips for Using Power Shears
- Mark clear and accurate lines on the metal sheets showing the areas you need to cut through for guidance
- Keep your eyes 1/2 inch ahead of the blade to improve your accuracy and precision
- In case you are a beginner, make sure you practice enough with the power shear before using it on your project
- Keep the blade always sharp. Blunt and thick blades can not only minimize efficiency but may also deform the metal sheet as well
- Take necessary preventive measures before initiating your work
