Grinding wheels/disks for angle grinders
Of the obvious and different types of discs for angle grinders, perhaps the most popular are grinding wheels. Grinding wheels come in different types and sizes.
The hardness or smoothness of a grinder is measured in grit. As with sandpaper, a low grit number on an abrasive disc means a coarser grind, while a high grit number means a less coarse grind. Low-grit discs remove material faster, but they produce more sparkles and have a rougher appearance. They can also create slight burn marks and many scratches compared to high-grit discs.

How To Choose The Best Cutting Disc For Metal | Ultimate Guide 2024
Gloves
In general, gloves and power tools do not get along well. This is because gloves can get caught in the moving parts of the tool and become a safety hazard. However, when cutting metal with a Dremel, I personally use gloves to protect my hands from sparks and hot metal. Choose what is right for you
Tools such as Dremel's can cause damage if the gloves get caught in the cutting tips. However, they are not as powerful as, for example, angle grinders.
Hearing protection
Dremel's are extremely noisy. It is therefore always a good idea to use hearing protection. It is up to you to decide whether to use headphones or earphones. To protect your precious ears.
Cutting metal with a circular saw
It may not be well known, but circular saws are a great tool for cutting metal. In our tests, we were able to cut armor like a hot knife cuts butter. With a steel cutting blade, you can cut mild steel up to 3/8 inch thick. But beware. Hot metal fragments can fly anywhere. Wear safety equipment, keep bystanders away, and cover anything on which you do not want to receive metal fragments. There are two types of blades: cheap steel and carbide. Carbide blades are more expensive but last longer.
Whether you have been a do-it-yourselfer for many years or are just getting started, there are some important tools for the job.
Thickness of the cutting disc
Cutting discs come in different thicknesses, and the type of disc you choose will depend on the type, shape and thickness of the steel you need to cut. For standard daily work on stainless or mild steel with an angle grinder, choose a thickness of 1 mm or 1.6 mm for your disc.
For projects involving thin metals such as sheet metal, choose thinner 1.0 mm or 0.8 mm cutting discs. These thinner discs flake through metal faster, minimizing discoloration and reducing the need to clean the metal surface at the end of the job.
When machining aluminum, it is advisable to apply wax or other types of lubricants to the cutting discs to preserve blade life and prevent chipping. For heavy steel cutting operations that require cutting metal of considerable thickness, choose 1.6 mm or 2.5 mm thick discs. However, keep in mind that thicker wheels cut more slowly, often discolor the workpiece and require additional finishing steps due to the friction and heat generated during cutting.
Selecting the profile of the cutting wheel
Before buying the best grinding wheel for your angle grinder, you need to know the types of grinding wheels available. There are two main types of cutting wheels. One is the flat type and the other is the type with a recessed center.
However, most of the angle grinders we use are compatible with the flat wheel type. Again, flat-type wheels are more effective when cutting materials such as metals and plastics. They are more versatile.
On the other hand, recessed-center wheels are more suitable for overhangs and sharp bends. For a better cutting experience, it is therefore better to use flat discs.
Building materials and grains
Most angle grinder wheels suitable for metal cutting are made of aluminum oxide grit. This is the most common material for wheels. The material provides soft adhesion to the wheel, making it easier to control and creating a fast cutting function.
In addition, the material does not control the iron contained in the disc. This is important if you want the disc to cut both mild steel and stainless steel.
Number of discs
The number of discs depends on the nature of the work. For DIY work in general, one disc is sufficient. However, professional craftsmen need different numbers of discs for different applications. So set a goal.
Ease of use and durability
If the grinder discs have a balanced size and diameter, they will be easy to install. It would also be appropriate to use the discs of smaller units if you are not able to do heavy cutting or industrial work.
Again, if the discs are made of high quality materials, they will serve and last longer than you might imagine.
Cutting metal with a circular saw
The circular saw is an excellent tool for cutting metal. In our tests, it cut rebar like a hot knife through butter. With a steel cutting blade, it can cut mild steel up to 3/8 inch thick. But beware. Hot metal fragments can fly anywhere. Wear safety equipment, keep bystanders away, and cover anything on which you do not want to receive metal fragments. There are two types of blades: cheap steel and carbide. Carbide blades are more expensive but last longer.
Whether you have been a do-it-yourselfer for many years or are just getting started, there are some important tools for the job.
Cutting aluminum with a miter saw
With a miter saw and a nonferrous metal cutting blade (check the label), it is easy to cut aluminum bars, pipes, and corners accurately. If the motor housing is open and metal fragments may accumulate, cover the opening with a cloth to protect the motor windings and bearings when cutting aluminum. This is to protect the motor windings and bearings when cutting aluminum (remember to remove the cloth when returning to normal use).
The motor will overheat). Inserting the aluminum between the wooden supports reduces the risk of metal fragments coming off and makes it easier to fix and cut the metal. This trick is especially important when cutting thin-walled objects. Without a backing plate, in fact, the blade often gets caught in the metal and deforms it, making it unusable.
Tips for cutting metal safely
When cutting or sharpening metal, small chips and metal fragments fly everywhere. They can then become hot and sharp. To avoid eye injuries, cuts and burns from cutting metal, observe the following rules
- Read and follow the safety precautions printed on metal cutting discs and blades.
- Wear safety glasses, face shield and hearing protection.
- Wear gloves, long-sleeved shirts and pants and cover all exposed skin.
- Cool before touching freshly cut metal.
- Wear gloves when handling metal with sharp edges.
- Hold metal firmly in place before cutting.
- Never let people near the metal while it is being cut unless they are wearing hearing and vision protection.
