If you need a tool to easily cut material, an angle grinder can be a great option to add to your tools. These grinders can perform quick cuts, grinding, sanding and polishing, and many other tasks. Of course, to get the best functionality and results you need the best angle grinder for cutting metal. Fortunately, we have already found the best option to get you started.
Best Angle Grinder For Cutting Metal
Angle grinders versus straight or die grinders
There are a couple of different grinders, and comparing the three main types will help you get a better idea of what an angle grinder is and why it is usually preferred over the other two types.
Angle grinders – The angle between the gear head and the disc is 90 degrees and is used in the hand. Presumably, this term arose to distinguish them from straight grinders, which carry the disc and grinding wheel at the end of the tool.
Straight grinder – The grinding wheel is angled at 90 degrees (relative to angle grinders) and is effective for grinding the outer or inner circumference, or when a separate grinding wheel is mounted. The angle makes it useful for various projects where an angle grinder might be a little more difficult to use.
Die grinders – Die grinders work much the same as straight grinders, but instead of an abrasive disc they use a die that acts like a drill bit. The abrasives used are usually small to fit into tight spaces and are ideal for deburring rough metal edges.
Corded, cordless and pneumatic angle grinders
Corded angle grinders – Corded angle grinders are those that must be plugged into a power outlet to operate. Their advantages are obvious: indefinite range and constant power when needed. They are also lighter and generally cheaper to own, as well as compared to cordless models.
Of course, if you use corded angle grinders, you need to be within range of a suitable power outlet and there is also a slight risk of accidentally sawing off the power cord, in addition to
Cordless angle grinders – Cordless (battery-powered) versions allow you to take the power supply with you. Cordless grinders are very useful for construction site work where the grinder is used on a ladder or scaffold. Modern brushless electric motors and lithium-ion batteries save you the hassle of recharging.
However, like most cordless models, fast-charging technology has made great strides to minimize downtime when charging tools; expect a 6Ah battery to take at least 30 minutes for a decent charge. They also weigh at least 2 pounds more than small corded angle grinders.
Pneumatic angle grinders – Pneumatic angle grinders take the idea of corded electric angle grinders to a whole new level. They must be connected to a suitable air compressor to work, but once connected they are the lightest angle grinders you can get. There are no batteries or electric motors, and operation is entirely pneumatic.
They are also among the most economical angle grinders you can find, once you have invested in a suitable air compressor.

How To Choose The Best Angle Grinder For Cutting Metal | Ultimate Guide 2024
Sizes
There are different sizes of angle grinders, generally ranging from 4 inches to 9 inches. You may find something a little smaller or a little larger, and these are usually specialized products. The 4-inch grinders tend to be the most expensive and work well for most purposes. The 5-inch grinders are suitable for cutting pipes a little easier than the 4-inch grinders. tend to be more expensive. Finally, 9-inchers are generally better suited for heavier materials such as steel and concrete.
Power
You need a system that has enough power to handle any cut. Most systems have between 500 and 2500 watts of power, but you can find some a little higher or a little lower. This can translate to a current of 4 to 15 amps, so consider what you need to do and make sure you buy a system that has the power to do it. Some projects will require you (and your tools) more than others.
Speed
There are several speed options that have a fairly wide range. For example, a low-level angle grinder may only have 5,000 rpm, while a more powerful one may offer 10,000 rpm. The higher the number of revolutions per minute, the more work can be done at one time. This is an advantage for those who expect more power and capacity from their tools.
Wheels
You will probably be able to fit at least one wheel on your grinder, but you want to make sure you can do more. You will need your grinder in the future, and if you don't have the ability to get another grinding wheel, you never know you will find yourself needing a completely new grinder. Before choosing a particular grinder, look for compatible wheels and brushes and more. That way, you will have more versatility in your system, even if you have to buy more accessories.
Shields
The system you choose should include an eye shield. This covers the wheel itself and ensures that your eyes are protected during sharpening. Without a shield, it is entirely possible that the object you are grinding will break, sending debris flying toward your eyes. You should always use a shield when grinding any kind of material. It will help you get the job done because it will allow you to see what you are doing without having to worry about your safety.
Handles
Finally, another great feature is the presence of a handle that can be moved. This handle can be locked on one side and the other, or it can have multiple positions. The presence of multiple support points allows for better functionality regardless of how it is mounted, so that left- or right-handed users can use the unit without having to worry about the comfort of use. The ergonomic handle should also allow users to use the unit for a long time without worrying about comfort.
Safety function
Some large angle grinders are equipped with a slow start function, whereby the motor slowly increases to full speed at startup to prevent immediate twisting. Kickback protection: angle grinders are equipped with a cutting function that interrupts the grinding wheel if it becomes entangled. Restart protection is a feature that prevents the grinder from restarting if it overheats or is left off.
Some grinders are equipped with a paddle switch (sometimes called a dead man's switch), which is a safety mechanism to ensure that the grinder is held with both hands and stops rotating when the switch is released. These features, while increasing in price, contribute to safety and can be indispensable on some construction sites.
Extras
When an angle grinder is purchased, it very often comes with a grinding wheel, lock nut and side handle. Some angle grinders may come with an abrasive disc and a case, which is included in the price. These grinders may be slightly more expensive than the basic models, but they are usually cheaper than buying them separately.
Disc diameter
The diameter of the disc is an important choice when choosing an angle grinder. The larger the disc, the greater the cutting depth of the machine. Usually, angle grinders with larger diameter discs are also more powerful.
Our angle grinders have disc diameters ranging from 4" (100 mm) to 9" (230 mm), with 4-1/2" (115 mm) and 9" (230 mm) grinders being the most popular choice. Smaller grinders spin the discs at higher speeds and are easier to handle. The disadvantage of small grinders, however, is that their discs need to be replaced more often, as they cannot cut as deep as larger angle grinders and have a higher wear rate.
Wattage
Higher wattages provide more power for cutting heavy materials such as thick steel. Higher wattages are also recommended for longer periods of use.
FAQs
What can angle grinders be used for?
Angle grinders were originally designed for abrasive discs, but their versatility and popularity have led manufacturers to adapt them to a variety of other applications.
Of course, grinding is the main reason for having angle grinders. Grinding wheels can be used to grind metal welds and sharp edges to a smooth finish that can be safely handled.
The most common use of angle grinders is for sanding and surface preparation. When equipped with a suitable sanding pad, they are very effective for removing old paint and dealing with rough edges and imperfections.
Pads are cheaper to replace than cannery blades, so it is common for old wood to be sanded with an angle grinder before being sent to the cannery.
Cutting is another area where angle grinders excel, and they are used with the appropriate cutting discs. A variety of cutting attachments allow them to cut masonry, tile, concrete, and metal, as well as softer materials such as plastic, wood, and PVC.
Abrasive discs and tips turn angle grinders into efficient finishing tools. They are also used to remove rust with a wire brush and to apply a matte finish to polished surfaces. They can also be used to quickly sharpen blades with the appropriate sharpening disc.
What is a flap disc?
A flap disc is a type of abrasive tool used for grinding and finishing metal, wood, and other materials. It is a circular disc made of multiple overlapping layers of abrasive cloth, arranged around a central hub. The abrasive layers are usually made of zirconia, aluminum oxide, or ceramic, which are highly durable and can remove material quickly and efficiently.
Flap discs come in a variety of shapes and sizes, with different grits and abrasive materials, to suit different grinding and finishing tasks. The most common shapes are flat and angled, and they can be used with angle grinders, die grinders, and other power tools.
One of the key benefits of flap discs is their ability to remove material quickly, while still producing a smooth, even finish. This is due to their unique design, which allows the abrasive layers to wear down gradually, exposing fresh layers of abrasive as they go. This also means that flap discs tend to last longer than traditional grinding wheels, making them a cost-effective choice for industrial and commercial applications.
Flap discs are widely used in metalworking, welding, and fabrication, as well as in woodworking and other crafts. They can be used for a variety of tasks, including grinding, sanding, blending, and finishing, and are often preferred over traditional grinding wheels for their versatility and ease of use.
Overall, flap discs are a highly effective and versatile tool for anyone who needs to grind or finish metal, wood, or other materials. With the right flap disc for the job, you can achieve a smooth, even finish in less time and with less effort than traditional grinding tools.
Which Is The Strongest Grinder?
The strength of a grinder typically depends on the motor power, which is usually measured in amps or watts. Therefore, the strongest grinder is typically the one with the highest motor power. However, the power requirements of a grinder depend on the specific application, so it's important to choose a grinder that meets your specific needs.
In general, angle grinders with higher motor power can handle tougher and more heavy-duty grinding tasks, such as cutting through thick metal or concrete. Some angle grinders with high power ratings can reach up to 15 amps or 2200 watts. However, it's important to note that high-powered grinders are typically heavier and larger, which can make them more difficult to handle for some users.
Corded grinders typically have higher power ratings than cordless grinders, as they can draw more power from the electrical outlet. However, cordless grinders have become more powerful in recent years, with some models boasting power ratings of up to 1200 watts.
Ultimately, the strength of a grinder depends on the specific application and the user's needs.

What Cannot Be Cut With An Angle Grinder?
While angle grinders are versatile tools that can cut a wide range of materials, there are some materials that are not safe or suitable for cutting with an angle grinder. Here are a few examples:
- Tempered glass: Tempered glass is a type of safety glass that is designed to shatter into small, rounded pieces when broken. While an angle grinder can cut through regular glass, attempting to cut tempered glass can cause it to shatter into many small, sharp pieces, which can be dangerous.
- Hardened steel: Hardened steel is extremely tough and durable, making it difficult to cut with an angle grinder. Attempting to cut hardened steel with an angle grinder can quickly wear down the cutting disc and potentially cause it to shatter, which can be dangerous.
- Granite or other hard stone: While diamond cutting discs are suitable for cutting through hard stone materials such as granite, attempting to cut these materials with a regular cutting disc can cause it to become excessively worn or damaged, which can be dangerous.
- Non-ferrous metals: Angle grinders are designed to cut through ferrous metals such as steel and iron, but they may not be as effective at cutting non-ferrous metals such as aluminum, brass, or copper. Attempting to cut non-ferrous metals with an angle grinder can cause the disc to become excessively worn or damaged, which can be dangerous.
It's important to always follow the manufacturer's instructions and safety guidelines when using an angle grinder and to only use the appropriate cutting disc for the specific material you are cutting. By using the appropriate cutting disc and taking appropriate safety precautions, you can ensure a safer and more efficient cutting process.
Can metal cutting discs be used on stone or concrete?
Metal cutting discs are not recommended for cutting stone or concrete. This is because metal cutting discs are designed specifically for cutting metal, and they are not suitable for the harder, denser materials typically used in stone or concrete.
Using a metal cutting disc on stone or concrete can lead to the disc becoming excessively worn or damaged, which can cause it to shatter and potentially cause injury. Additionally, metal cutting discs may not be able to make clean cuts in stone or concrete, leading to a less accurate and more time-consuming process.
For cutting stone or concrete, it is recommended to use a diamond cutting disc or blade. Diamond cutting discs are designed specifically for cutting hard materials, and they are able to make clean and precise cuts with minimal chipping or damage to the material. Diamond cutting discs are available in different sizes and thicknesses to suit a range of cutting applications.
When using a diamond cutting disc, it is important to follow the manufacturer's instructions and take appropriate safety precautions, such as wearing personal protective equipment and securing the workpiece properly. By using the appropriate cutting disc for your specific application, you can ensure a safer and more efficient cutting process.
How can I avoid sparking when using a grinder?
Sparks are a common hazard when using a grinder, and they can lead to fires, explosions, or serious injury if proper safety precautions are not taken. Here are some steps you can take to avoid sparking when using a grinder:
- Use the correct wheel: Use a wheel that is appropriate for the material you are grinding, and ensure that the wheel is compatible with your grinder. Using the wrong wheel can lead to overheating and sparking.
- Keep the wheel clean: Over time, grinding wheels can become clogged with metal particles and debris, which can increase friction and lead to sparking. Keep the wheel clean and free of debris by using a wire brush or dressing tool to remove particles.
- Check the wheel speed: Ensure that the speed of your grinder matches the speed rating of your grinding wheel. Operating the grinder at a higher speed than the wheel is rated for can generate excessive heat and sparks.
- Secure the workpiece: Ensure that the workpiece is properly secured before grinding, to prevent movement and sparking.
- Use a spark guard: A spark guard is a barrier that can be placed between the grinder and the workpiece to prevent sparks from escaping. Always use a spark guard, and ensure that it is in good condition and securely fastened.
- Use personal protective equipment: Always wear appropriate personal protective equipment, such as safety glasses, a face shield, and leather gloves when using a grinder. This can help protect you from sparks and other hazards.
By following these steps, you can reduce the risk of sparking when using a grinder and minimize the risk of injury or damage to property. It's important to always prioritize safety when working with power tools.
How can I be sure that my new grinding wheel is free of defects?
Ensuring that your new grinding wheel is free of defects is important for safety and to ensure that the grinding process is efficient and effective. Here are some steps you can take to check your grinding wheel for defects:
- Inspect the packaging: Before opening the packaging, inspect it for any signs of damage or rough handling during shipping. If there are any signs of damage, it's a good idea to return the product.
- Check the labeling: Look for labeling on the grinding wheel that includes the manufacturer's name, the wheel type, size, speed rating, and any safety information. Ensure that this information matches your intended use.
- Inspect the wheel for damage: Before using the grinding wheel, inspect it for any signs of damage such as cracks, chips, or nicks. If you see any damage, do not use the wheel.
- Check for balance: A balanced grinding wheel will operate smoothly and prevent vibrations. To check the balance, attach the wheel to the grinder and spin it. If the wheel wobbles or vibrates, it is not balanced and should be replaced.
- Conduct a ring test: A ring test can help you identify any cracks or defects in the grinding wheel. To do this, hold the wheel by the center hole and tap it lightly with a non-metallic object, such as a wooden dowel. If the wheel emits a clear and bell-like tone, it is in good condition. If the tone is dull or flat, it may have a crack and should not be used.
