Cutting metal – tools, methods and practical tips
Anyone who regularly works with metal sooner or later asks how metal can be cut cleanly and safely. Depending on the material, material thickness and area of application, different tools and methods are used.
In this article, you will learn which options are available for cutting metal, how mechanical and thermal cutting methods differ, what role the type of metal plays and which safety measures should definitely be observed.
At the same time, the guide shows when it makes more sense not to cut metal yourself, but to order metal cutting made to measure directly online. This allows you to combine practical workshop knowledge with a precise solution for sheets, profiles, tubes, bars and folded parts.
Which tools are suitable for cutting metal?
Which tool is the right one depends mainly on the type and thickness of the metal as well as the desired cut quality. For many DIY applications, simple hand tools are already sufficient, while electric machines are used for thicker materials or particularly precise cuts.
The most common tools include:
- Sheet metal shears – ideal for thin aluminium or steel sheets
- Metal saw – suitable for tubes, profiles and smaller workpieces
- Jigsaw with metal saw blade – for straight and curved cuts
- Band saw – precise and efficient for profiles and solid material
- Angle grinder – particularly versatile for steel and stainless steel
- Plasma or laser cutter – for professional applications with high precision
Which tool is most suitable ultimately depends on the specific project. A suitable saw blade or cutting disc and secure fixing of the workpiece are important.

Mechanical or thermal cutting methods – what are the differences?
A basic distinction is made between mechanical and thermal cutting methods. Mechanical methods separate the material through a cutting movement. These include sawing, shearing or punching, for example. They are particularly suitable for smaller workpieces, generate only little heat and generally do not change the material properties.
Thermal methods, on the other hand, work with high heat. These include laser, plasma or flame cutting, among others. They enable particularly precise or fast cuts, but are mainly used in industrial production.
Both methods have their advantages. While mechanical methods are sufficient for many workshop and DIY projects, thermal methods offer advantages especially for complex contours or larger material thicknesses.
| Method | Advantages | Typical application |
|---|---|---|
| Mechanical cutting | Lower heat development, good for workshops, DIY projects and many standard cuts. | Sawing, shearing, punching, cutting profiles, cutting tubes, cutting sheets |
| Thermal cutting | High precision, fast cuts, complex contours and industrial applications possible. | Laser cutting, plasma cutting, flame cutting, professional metalworking |
| Professional metal cutting | Exact dimensions, clean edges, less waste, less reworking and predictable further processing. | have metal cut, order metal cutting online, configure metal made to measure |
What role does the type of metal play when cutting?
Not every metal can be processed in the same way. Hardness, material thickness and thermal conductivity influence which cutting technique delivers the best results. It is especially important that the tool, saw blade, cutting disc and cutting speed match the respective material.
A brief overview:
- Aluminium: Soft and easy to process. Saws or sheet metal shears often deliver clean results.
- Steel: Requires more robust tools and often somewhat more force. For thicker materials, an angle grinder or band saw is often suitable.
- Stainless steel: Due to its hardness, high-quality saw blades or cutting discs are required. In addition, a lower speed should be used to avoid overheating.
- Brass and copper: Easily machinable non-ferrous metals where secure fixing, suitable tools and controlled feed are important.
- Galvanised steel: When cutting, the zinc layer should be taken into account, especially if corrosion protection or a coating is relevant later.
Choosing the right cutting technique not only contributes to clean cut edges, but also extends the service life of the tools used.
Cutting metal by material: aluminium, steel, stainless steel and sheets
| Material | What to pay attention to? | Matching entry point |
|---|---|---|
| Cutting aluminium | Soft material, good machinability, suitable for sheets, profiles, tubes and bars. | Aluminium profiles made to measure |
| Cutting stainless steel | Harder material, use a clean cutting disc, avoid overheating and contamination. | Stainless steel profiles made to measure |
| Cutting steel | Robust material, suitable for load-bearing constructions, profiles, tubes, beams and workshop construction. | Steel profiles made to measure |
| Cutting sheet metal | Material thickness, surface and cut edge are decisive. Thin sheets can be separated mechanically. | Sheets & plates made to measure |
| Cutting profiles | Exact length, clean angle and secure fixing are particularly important. | Metal profiles made to measure |
| Planning folded parts | If a functional component is to be made from sheet metal, cutting and bending should be considered together. | Folded parts made to measure |
Cutting metal safely – what you should pay attention to
When cutting metal, sparks, sharp edges and sometimes high temperatures occur. The work should therefore always be carefully prepared. In addition to the right tool, occupational safety, workpiece fixing and clean finishing are decisive.
Important safety measures include:
- wear safety goggles and work gloves
- clamp or fix the workpiece securely
- use a suitable tool for the material and material thickness
- replace damaged cutting discs or saw blades immediately
- take flying sparks into account and remove flammable materials
- deburr cut edges after processing
- when working with stainless steel, use clean tools to avoid foreign rust and contamination
- for coated or galvanised materials, include the surface and corrosion protection in the planning
Anyone who observes these instructions reduces the risk of injury and at the same time achieves better work results.
Deburring metal and finishing cut edges
After cutting, sharp edges, burrs or small material residues often occur. These should be removed before the metal part is further processed, assembled or painted. Especially with sheets, tubes and profiles, a clean edge is important so that the component remains safe, precisely fitting and visually neat.
- Deburring tool: suitable for many cut edges on sheets, tubes and profiles.
- File: helpful for stronger burrs or smaller workpieces.
- Sandpaper: suitable for fine finishing and light edge corrections.
- Grinding machine: useful for larger edges, robust components or series work.
For visible components, finishing can be particularly important. Depending on the project, a surface treatment such as powder coating can also be useful afterwards.
Metal made to measure – less effort when cutting
Not every piece of metal has to be cut by yourself. Anyone who orders sheets, profiles or tubes already precisely fitting saves time, tool costs and reworking.

Frequently asked questions about cutting metal
Can you cut metal without an angle grinder?
Yes. Thin sheets can be cut with sheet metal shears, for example. For profiles or tubes, metal saws or jigsaws with a suitable metal saw blade are suitable. Which method is best depends on the material and the material thickness.
Which tool is suitable for aluminium?
Aluminium is comparatively soft and can be worked well with sheet metal shears, a metal saw or a jigsaw. A suitable tool for non-ferrous metals is important.
Why do burrs form after cutting?
When cutting metal, sharp edges or small material residues often occur. These should be removed with a deburring tool or sandpaper to avoid injuries and smooth the surface.
Can stainless steel be cut with a normal cutting disc?
Special cutting discs should be used for stainless steel. They ensure clean cuts and prevent contamination that could impair the material’s corrosion resistance.
When is it worth having metal cut?
Professional metal cutting is worthwhile when exact dimensions, clean cut edges, several identical cuts or direct further processing are important. This reduces measurement errors, waste and reworking.
Which metals can be cut to size?
Typical metals for cuts made to measure include aluminium, stainless steel, steel, galvanised steel, brass and copper. Depending on the project, sheets, plates, profiles, tubes, bars or folded parts can be selected.
What is better: cutting metal yourself or ordering metal cutting?
For simple DIY work, cutting it yourself can be sufficient. However, if exact dimensions, clean edges, multiple parts or professional results are required, metal cutting made to measure is usually the better solution.
Conclusion
Metal can be cut cleanly and precisely with the right tools. Whether sheet metal shears, metal saw or angle grinder – the decisive factors are the properties of the material, the appropriate cutting technique and safe handling of the tool.
Anyone who also relies on precisely fitting cuts saves time and significantly reduces the amount of processing work.
