The cheapest tool for cutting tin and sheet metal accurately is with a simple pair of aviation snips a tool that’s also known as tin snips.
Tin snips can be used for crafting both metal artwork or corrugated roofing metals. Even plastic, car panel and wire cutting jobs can be done with a good pair of these hand metal cutters.
Tin snips are safe, cheap, accurate, and easy for beginners to use, but they are not very fast cutting for big jobs. You should think instead about getting electric shears or better a sheet metal nibbler.
Offset tin snips are much easier to use compared to blades that are not offset. And for that reason, all the tin snips here in this review have an offset cutting blade.
You might wish you had a pair of electric tin snips, and they do actually exist. Metal cutting shears are available as both a dedicated tool and an impact driver attachment.

Tin snips are hand-operated shears that look like long-handled scissors with short, sharp blades. They are made of stronger metal than most scissors so that they can cut through some pretty tough materials.
Tin snips aren’t only limited to cutting tin–they can also be used to cut anything from plastic and cardboard to rubber, and even sheet metal.
Tin snips are typically used for cutting and trimming thin metal sheets to specific measurements. They can also be used to cut out shapes from sheet metal, making them useful for metalworking and home DIY projects.
Tin snips are commonly used for cutting and trimming metal for car modification, restoration, and repair. They can also be used to shape metal components for HVAC systems.
For DIY applications, tin snips can be used to create metal parts for furniture, fences, roofs, and gutters.
Some tin snips are designed for cutting through heavier metal materials such as wire mesh or netting. For really tough materials, straight pattern tin snips–often referred to as aviation snips–are preferable due to their serrated blades and more robust construction.

Best hand tools for cutting metal
Straight cut tin snips
Straight cut tin snips can cut through metal quickly and efficiently. They are especially useful at making straight cuts, and they don’t cause dimpling in the material being cut. The cuts you can achieve with straight cut tin snips are pretty smooth, making them excellent choices for finishing work.
Some straight cut tin snip blades are too long and bend out of place and then stop cutting. So keep in mind that a pair of straight-cut tins snips with a longer blade inst necessarily better, unless you are cutting something like thin tin or plastic.
The pair above is a good-sized blade for a straight cut aviation cutter.
Corner cut tin snips
Corner cut tin snips are better suited for shaping and corner work. Coppersmiths and custom metalworkers often use corner cut tin snips in conjunction with straight cut tin snips for precision work and cutting out intricate shapes in metal.
But better known as a pair or left or right-handed tin snips. If the color of the tool is green this indicated a right-hand pair. And red indicates a pair for cutting corners to the left. You can still cut straight lines with either pair.
Seamers are primarily intended for bending light gauge sheet metal. They can also be used to make cuts into sheet metal with the addition of a cutting blade.
Keep in mind that you will lose a bit of functionality when using a seamer in this manner. Furthermore, you risk breaking the tool if it is bent beyond the normal limit. Seamers are best used for bending metal tabs in a tidy fashion, most used for making up flashing details.
Electric sheet metal shears
Electric shears are a metal cutter that can come as dedicated tools or as drill bit attachments. They can cut through metal pretty quickly, and allow you to cut straight lines much more easily as compared to tin snips or nibblers.
Electric shears like the Malco Turbo shears are also ideally suited for cutting roofing material hidden under ridges. Important to know that there are 2 different metal cutting attachments made by Malco, a standard pair for sheet metal cutting and a dedicated pair for cutting corrugated iron.
Malco even does an attachment for cutting fiber cement sheets, if you are a builder you might not know about this and it could be a handy tool to have.
Hand nibblers cut through metal effectively, but slowly, they only take a little bit of material off the workpiece with each punch.
They can cut across roofing material pretty well for doing small detailed work in tight corners, making them useful tools for some roofing work.
For tight corners and precise cuts, you might want to use a hand nibbler in conjunction with tin snips. Hand nibblers can also be used for sheet metal art, like copper art.
Electric nibblers can cut through metal in the same way as a hand nibbler, but they are much more effective for roofing jobs as they are a power-driven tool.
They do cost more, so you might want to hold off on buying one unless you have to do a lot of metal cutting work. Even with electric nibblers, it is necessary to finish up with tin snips for corners and detailed areas.

Nibbler drill attachment
If you have an impact driver, you could get a nibbler attachment that expands its capabilities and allows you to use it to cut through metal sheets in a similar way that a nibbler does.
Nibbler attachments are a good option as they are much cheaper and do the same job as a dedicated nibbler, however, they are good if you only have to do occasional and a small amount of metal cutting work. For trade use they are under-powered.
A nibbler drill attachment can pair well with an electric shear. You can use an electric shear to cut the bulk of the straight cuts, and then use this nibbler drill attachment to cut around steep corners.
The CaNibbler is a good option for this.
When to use tin snips?
Tin snips are the best options when you need a quick, easy, and inexpensive way to cut metal roofing materials, they are also very easy and safe to use and make an accurate cut with. For most roofing work, it would be best to have a straight-cutting pair of snips, as well as a left-handed or right-handed pair, depending on your preferences.
Having these options will allow you to perform a wider variety of jobs, from straight to corner cuts.
Tin snips allow you to make precisely controlled cuts. These tools are ideally suited for cutting edges of corrugated iron that will be visible after the project is completed.
Other tasks that tin snips can handle effectively are cutting galvanized steel and plastic flashings.
They are also useful for cutting stainless steel–if the material is thin enough–and for intricate copper work.
Tin snips cut copper like butter as copper is soft this makes them ideal for shaping copper artwork as well.
When not to use tin snips
Tin snips probably aren’t the ideal choices when you need to cut excessively thick material. Trying to cut material that is thicker than the snips are capable of will likely cause the blades to separate, resulting in rough or uneven cuts.
You could experience similar issues with tin snips that have excessively long blades without the ability to re-tighten them.
Cheaper tin snips can give you even more trouble, due to weak blades that tend to bend outwards and not cut into the material at all.
Most tin snips–particularly those of the cheaper variety–will suffer from this problem eventually, so it is always better to pay a little more money for a robust model that will give you longer service.
Although you could use tin snips to cut through fairly thin corrugated metal roofing, the work is often slow and difficult. Depending on how thick the material is, you might be better off using a hand nibbler or electric shears.
Metal cutting jobs for tin snips
Tin snips are best suited for metalworkers and DIY’ers that want to make accurate cuts. Even though snips are relatively cheap tools, they can make clean and precisely-controlled cuts that even costlier devices would have difficulty doing.
One of the best uses of tin snips is to clean up edges that you first cut with a nibbler. For example, you can quickly cut roofing material to about half an inch longer than the intended length or width.
After installing the roof, you can then trim the excess with a good pair of tin snips if it is a visible and seen cut edge.
Tin snips are also useful for cutting large pieces of sheet metal. For this purpose, however, you should make sure that the sheet is large enough so that you can twist the off-cut away and keep the snips on a straight path with-out the blade jamming.
Best electric metal cutting shears
Shears are useful tools for making straight cuts into sheet metal. They are often presented as a more efficient alternative to nibblers or tin snips, enabling users to cut through corrugated metal with minimal effort.
Electric shears give you the ability to cut through sheet metal materials with ease.
There are dedicated electric shearing power tools like the cordless Milwaukee, but you could also purchase a shearing attachment for your impact driver instead, as a more cost-effective option.
Check out the Malco TSHD Turboshear that could take the place of most nibblers or tin sniping jobs when it comes to cutting corrugated iron.
Best tin snips for metal roofing
The best tin snips for cutting metal roofing are the same as what’s above in this review, tin snips that are off-set are less likely to get jammed when cutting, and are also less likely to have the blades stretch apart.
But for cutting metal roofing have a look at the electric shears tool that is pretty much just electric-powered tin snips.
What are the different colors of tin snips mean? Green colored tin snips are known as right cut snips, red is generally left cut and straight cut has a longer cutting blade and are generally yellow.
Best tin snips for cutting metal studs?
The best tin snips for cutting metal studs are what is outlined in this review, the best pair of off-set tin snips are what you need for cutting metal studs.
Some commercial steel wall systems have a steel top and bottom plate that is to thick for tin snips, so for thicker metal-cutting jobs, have a read of my angle grinder reviews.
Another idea is to bulk cut metal studs using a metal chop saw is much faster.
Tin snips for copper art
Creating copper wall art is a process that requires precision and a steady hand. Tin snips can be useful for cutting out shapes precisely, making them especially suitable for copper work.
As with highly intricate metalwork, you will get better results by using a straight cut pair of tin snips in addition to left- or right-handed snips for cutting corners.
In some cases, you might be able to make more precise cuts into copper with a good pair of hand nibblers. Some copper workers find that they can get the best results by alternating between tin snip and hand nibblers.
Tin snips are a must-have tool in your toolbox really. They are versatile enough to cut through a variety of materials, from plastic and cardboard to even stainless steel and copper.
They are also the cheapest metal cutting option, and you could easily afford to have two or three different snips on hand for various tasks.
If you do a lot of metal roofing, for instance, an electric nibbler will let you cut through roofing materials more quickly. Even so, you might still want to have a pair of tin snips around for finishing work.
