Effective in cutting and scissors on metal. Depending on the type and thickness of the material, the following types of tools are distinguished:
- ordinary hand scissors (used for sheet steel with a thickness of 0.4. 1.1 mm);
- Chair scissors (have large dimensions and are suitable for steel up to 2.5 mm);
- power scissors (for steel up to 5.0 mm);
- Lever or hand shears (for long material with thickness up to 3.0 mm);
- guillotine shears (have inclined knives, suitable for thick steels up to 32 mm).
What is the best choice for scissors for sheet metal??
If the task is to cut the roofing sheet of only a few places, and they do not need to handle with extremely high accuracy, it is enough to buy a sheet metal shears the most simple model. True, it is very important to check the quality of the blade. it must be properly sharpened and very sharp. Practice shows that beginners do not work well with used tools, only an “experienced hand” can qualitatively cut metal with bad scissors. Well, of course, avoid the cheapest models. they do have a very limited lifespan.
If you need to prepare the roofing sheets on the roof of the whole house, or process a large amount of sheet metal, we recommend buying special scissors for cutting metal. nibblers. Of course, if you have a lot of free time, you can try and hand-cut the metal, but it is quite a tedious procedure when it comes to dozens of metal sheets.
For professional use, you will need all kinds of tools: both sheet metal shears and classic scissors and battery-powered hand scissors. it is unknown which tool is better for the order, so you should be prepared for any situation.
The choice of cutting tool depends on the hardness and thickness of the metal. For cutting thin sheets of metal, for example, a pair of metal shears is sufficient.
When cutting metal sheets 4-7 mm thick by hand, you should use a jigsaw or electric scissors. It is better to cut steel pipes with a metal hacksaw.
Hand tools for cutting metal
When using a hacksaw, make sure it has a blade that is specifically designed for cutting metal. Otherwise, you will be disappointed.
The metal blade must be firmly fixed in the frame of the hacksaw.
[su_note note_color=#535353 text_color=#fff]Note: the cutting blade is correctly tensioned if it has not sagged when pressed from the side. Otherwise, you should tighten with a coupling screw, but do not overdo it. there is a chance of ripping off the thread.[/su_note]
Cutting metal profiles with an electric jigsaw
Manual cutting of metal sheets of sufficient thickness is made with an angle grinder (angle grinder). A special cutting disc marked METAL is mounted on it, do not be confused. First slide the support washer onto the spindle, then place the cutting disc. Don’t forget to wear safety glasses and gloves.
[su_note note_color=#535353 text_color=#fff]Warning: very often, especially when cutting thick metal, the saw blade “kicks” and the fastening nut is strongly tightened. To avoid it, some gasket, specially cut from thick paper, should be put between disk and jam nut. If, however, the nut is so tight that it can not be loosened, gently break the cutting disk all the way to the base of the tightening nut. Take a metal blade, guide the cutting part of the blade into the opening of the tightened cutting disc residue. Again, carefully, by periodically turning on the angle grinder, saw out the remains of the cutting disc.[/su_note]
In order to make cutting easier by hand, the angle grinder always comes with a side handle. Don’t forget to use it.
Securing the workpieces
When hand-cutting metal sheets with an electric jigsaw or metal scissors, the workpiece must be placed on a flat, wide surface and secured with clamps. And when cutting metal with a hacksaw always clamp the workpiece in a vise.
Never saw a piece on your lap, in your hands, or by weight. This causes the cutting blade to break and often results in injury.
The choice of cutting attachment depends on the hardness and thickness of the metal. So, for cutting thin sheets of metal, a pair of metal scissors may be adequate.
If you cut metal sheets 4-7 mm thick manually, use a jigsaw or electric scissors. Steel pipes are best cut with a metal hacksaw.
When using a hacksaw, make sure it has a blade that is specifically designed for cutting metal. Otherwise you will be disappointed.
The metal blade must be firmly fixed in the frame of the hacksaw.

Fixing the workpieces
When manually cutting sheets of metal with an electric jigsaw or scissors for metal, the workpiece should be placed on a flat, wide surface and secured with clamps. And when cutting workpieces with a metal saw always secure the workpiece in a vise.
Never cut blanks on your knees, in your hands or by weight. This leads to breakage of the cutting blade, and often to injury.
Types of scissors scissors
Metal tile has a complex surface relief, because of which cutting sheets by conventional scissors is extremely problematic, you have to use cutters. They have a universal purpose, they are equally good at making straight or curved cuts. Tool maneuverability depends on the length of the die holder. Electric scissors for cutting metal tiles come in 3 types:
Cutters. The mechanism of this tool is simple: each stroke of the punch cuts a piece of metal in the sheet metal. They are used for processing metal tiles, profiled sheeting, pipes, welded structures. Cutting scissors can cut the sheet from the edge to the middle, and in the opposite direction, if you make a hole in the starting point with a drill.
Experienced craftsmen recommend that before you cut the metal tile, to practice on the rest of the material to make a precise and straight cut. Furthermore, only tools recommended by the manufacturer should be used.
Metal cutting by laser
As the name suggests, the main tool for processing the material in this case is a laser beam. Industry produces machines that vary in power and speed. The lasers used in them can be:
- Gas lasers, with discharge tubes filled with helium, nitrogen, or carbon dioxide.
- Fibers. In this case a fiber optic is used as a beam generator.
- With solid-state. Their design uses neodymium glasses, ruby or garnet crystals.
The type of installation affects the technical characteristics. However, no matter what kind of laser cuts metal, the thickness of the material to be treated does not exceed 40 mm. The advantages of laser cutting include:
13 Ways to Cut Metal
- Cutting accuracy. Important for both artwork and the production of complex mechanisms.
- Processing speed that exceeds other cutting technologies.
- Smoothness of the cut. No dross on the finished parts, meaning no rework.
- Very little waste. This has a positive effect on the cost of the finished product.
- Minimum heating of processed parts. Only the cut zone is exposed to critical temperatures.
Laser cutting equipment is versatile and highly automated. However, it also has disadvantages:
- High cost. True, some of the cost of the machines is recovered through less waste and low operating costs.
- Limiting the thickness of workpieces. For medium power installations this parameter is limited to 20 mm. As the thickness of the material increases, the cutting speed decreases and energy costs increase.
- Impossible to work metals with high reflectivity and high strength.
These disadvantages limit the use of laser cutting systems.
What is the best way to cut metal with your own hands
Metal cutting tools should be selected according to the precision and thickness of the workpiece. Different methods of cutting are used at home.
Frequent bending and unbending
The method is relevant for working with soft metal blanks (wire, strips, rods) of small thickness. The technology is only suitable for roughing: not very precise, but very handy when nothing else is available except for the pliers.
You can also use a hammer and vise: clamp the workpiece in them and beat, bending and unbending the metal.
Metal chopping with a chisel and hammer
The process also belongs to roughing. In addition to a chisel and hammer, you will need a clamp or vice. Make a mark, clamp the workpiece, and start chopping.
Picture : metal chopping with chisel and hammer
Wire cutting pliers may be good for cutting wire. If you cannot cut the material by hand, you must hit the tool with a hammer, in which the workpiece is clamped.
Metal hacksaws consist of a frame and cutting blade. Algorithm: make a mark, clamp the workpiece with a clamp or vice, and start cutting.
Picture 0: cutting metal with a hand hacksaw
Theoretically, you can cut a thicker workpiece with a metal hacksaw, but it will require serious effort and time.
Suitable for rough cutting of thin soft metal.
Picture 1: cutting metal with hand scissors
For processing thick workpieces, there are ways to reinforce the tool.
- Fix one handle of the scissors in a vice, and put a long piece of pipe on the other handle. The result will be a lever that will increase the force several times.
- You can also use a hammer. It is used to hit the upper handle of the tool in which the workpiece is clamped.
If you strengthen the hand scissors, it is possible to cut metal with a thickness of 2-3 mm. However, it will worsen the quality of cutting.
To process the workpiece with the jigsaw, a special saw blade must be inserted. This tool is perfect for cutting sheet metal, as well as angles, pipes, rods, etc.
Photo 2: cutting metal with an electric jigsaw
You can cut shaped pieces with the jigsaw. At the same time high accuracy is achieved. The main disadvantage of the method. not too high speed.
angle grinder already mentioned in the article. Great for non-professionals due to its versatility.
Accuracy of metal cutting will be high if there are no errors. Finishing workpieces can be finished with scribing and polishing wheels. Another advantage of a segment mower is its good performance (on a domestic level).
Sabre saw (electric hacksaw) is more expensive and better suited for cutting metal than an electric jigsaw or angle grinder, for three reasons:
- Enlarged cutting tool dimensions. electric hacksaw can be equipped with saw blades up to 35 cm long
- Increased productivity. sabre saws have more powerful electric motors;
- excellent cutting quality. the amount of waste is minimal.
Photo 3: cutting metal with a reciprocating saw
As the name suggests, this tool is designed for cutting pipes of small and large diameters. Sharp rollers are in direct contact with the metal at the place of cutting.
Picture 4: cutting metal pipes with a pipe cutter
The pipe cutter is best suited for soft (copper, aluminum) pipes. The main disadvantage of the tool is its narrow purpose.
Electric multitools (Renovators) have metalworking attachments. But they are not suitable for cutting thicker workpieces.
Photo 5: cutting metal with a multitool
Multitools are most often used for trimming protruding nails and bolts. Renovators’ main advantage is the ability to work in hard-to-reach places.
Excellent tool, used by hobbyists and professionals alike. Budget models are designed for cutting sheets up to 2 mm thick, and expensive analogues can handle more complex work.
Photo 6: Cutting metal with pneumatic scissors
The main advantage of pneumatic scissors is the very high quality of metal. Cutting with this tool does not impair the protective properties of tiles, corrugated board and other materials with special coatings.
This type of cutting of sheets and production of blanks from pipes or sections is very common and is used both industrially and in cottage industry. Mechanical cutting of metal is performed using circular or reciprocating band saws, both on manual circular sawing equipment (angle grinder) and stationary (cut-off machine). Metal chopping and cutting is also performed on guillotine-type shears, which are hydraulically, pneumatically, electrically or hand-operated. They operate on the principle of parallel motion of the two cutting edges, the gap between which is minimal. By pressing a sheet of metal from both sides, the sharp edges cut through it and form an even line of cut with minimal edge deformation.
Metal cutting tools for pipes and profiles most often use metal saws. circular or band saws. Metal band saws are made of spring steel, and its teeth are coated with a particularly durable alloy. As a general rule, cutting bandsaws can handle all types of metal, including hard alloys. But the dimensions of the workpieces to be machined are limited by the dimensions of the work table. But metal cantilever or gantry saws, where the saw unit itself moves rather than the workpiece, can handle fairly large workpieces.
Based on circular saws created machines for longitudinal-transverse cutting, allowing to save time in the manufacture of any parts according to GOST or TU of sheet metal. They are programmed to the necessary parameters and perform all operations simultaneously for cutting.
To work with their own hands are most convenient angle grinder and cutting machine based on circular saw (cutting wheel). The circle is made of a special material that causes a great force of friction when rotating on the surface of the metal, resulting in a huge temperature, which simply burns through the metal, and the red-hot residue is removed by the circle itself when rotating.
Cutting and chopping of corrugated sheet is made by electric shears with a special attachment. a mechanical guillotine, which is easy to make your own hands. Or roller blades are used. Cut profiled sheet with an angle grinder can not. Cutting metal also requires a special tool, it is made of the same trapezoidal sheet, but with a different form of corrugation.
But for aluminum it uses a special machine for cutting aluminum profile with a cutting wheel. It is a reduced version of a stationary cutting machine for steel. Its purpose. preparation of profiles for various frame structures or window and door frames. It is possible to cut aluminum either perpendicular to the wall or at an angle.
