You can adjust the guard and replace the wheel easily, and the grip is comfortable, which are all important.

The wheel has a standard 4 ½-inch diameter, and the unit features kickback protection with the safety slip clutch. Whether you want to cut or grind, you can easily adjust the guard to your needs.
The ergonomic handle ensures comfortable use, but the “weight” is also one of the comfort factors since this tool weighs only 2.4 pounds. The switch location isn’t exactly convenient. Although you will get used to it after a while, you still won’t feel it provides optimal comfort.

8. Makita 9557PBX1 4-1/2-Inch Angle Grinder

Makita-9557PBX1-Angle-GrinderWhen you see the specifics of this unit, it becomes unbelievable that it weighs only 4.5 pounds. Makita managed to pack a 7.4AMP motor in that size, which is commendable.

We also liked the metal gear housing, which secures optimal durability.

The gear housing is rotatable, which is convenient, and you can choose the side where you will place the side handle. The tool is quite versatile and suitable for grinding, cutting, and polishing. The blade ensures a fairly smooth cut and finish, and you should be satisfied with the results. The product comes with a box that looks neat, but it probably won’t fit any additional accessories you buy, and Makita could have made it a bit bigger.

9. DEWALT DWE402 4-1/2-Inch 11-Amp Paddle Switch Angle Grinder

PORTER-CABLE-PCC761B-20-volt-MAX-Lithium-Bare-Cut-Off_GrinderWhile you cannot expect an ample amount of power from a portable grinder, Porter Cable managed to design a unit that performs quite well.

Everything you might expect is there – the classic 4 ½ inch diameter of the wheel, as well as the option to easily change it with the spindle lock. Users can adjust their preferred side handle positions and replace guards whenever that is necessary.

The battery is reasonably durable, and the metal gear housing enables extended use because it dissipates heat during long-term working. The overall quality of the components could be better, but keep in mind that this is a low-cost unit. Finally, the tool is a bit heavier than expected with the weight of around six pounds.

11. Bosch 4-1/2-Inch Angle Grinder 1375A

Thanks to the solid power of this electric grinder, you can use it for pipe fitting, concrete restoration, metal fabrication, and other applications.  The sealed switch prevents debris and dust from entering the mechanism, and integrated brushes will stop the tool when preventative maintenance is necessary. A small downside is that it is not that easy to change the guard because you need to use a wrench. Fortunately, the tool comes included with the grinder.

12. BLACK+DECKER BDEG400 6 Amp Angle Grinder

BLACK+DECKER-BDEG400-6-Amp-Angle-GrinderThe goal of Black+Decker was to create a small grinder that packs a lot of power.

The tool operates at a speed of 10,000RPM, and you can use it for grinding, cutting, sharpening, preparing surfaces, and removing rust. The motor uses electricity as a power source, which enables extended use and long-term operation. Multiple positions of the size handle and a quick-release switch to turn off the unit rapidly are also among the included features.

It may be a small downside, but the wrench included seems to be of poor quality, so you might have to use a different one to change the wheel. Additionally, the product manual doesn’t get into details, but you should still quickly learn how to use this product.

Angle Grinder Buying Guide

We will start this buying guide with the list of questions you want to ask during the purchasing process.

What to Consider When Buying an Angle Grinder

  1. How powerful do you want your angle grinder to be?

    The more power, the better, but keep in mind that will also increase the price. That is why you want to find the optimal balance between the two.
    Try to consider how you plan to use the tool. If you want to use it for light-duty tasks around your home, a grinder with a modest power should be enough. However, hard materials like concrete or stone might require more power.

  2. Do you need it to be portable?

    Portable angle grinders are suitable when you need to take the tool from one job site to another. Additionally, they are cordless, and they do not depend on an available electrical socket.
    However, they do not pack that much power, and you should always make sure there is sufficient battery or fuel left in the tank.

  3. What safety features does the unit have?

    Safety is important, especially if you are a beginner who hasn’t used an angle grinder before. Some of the usual features include overheating and kickback protection. The latter enables automatic shut-off in case anything goes wrong. Apart from that, you will want to purchase safety glasses. Some manufacturers might deliver them with the tool, but you may need to buy them separately.

  4. Is the handle comfortable?

    In most cases, you will find a side handle with multiple potential positions. Those handles you can mount on any side of the tool make it suitable for left and right-handed operators. Additionally, you want to ensure the handle has a rubber grip as that reduces the risk of fatigue when operating the grinder for long.

  5. Is it easy to replace the wheels, guards, and other accessories?

    As you get better with using your grinder, the chances are you will look start experimenting with different wheels and other accessories. That is why interchangeability is a vital feature. You need to be able to replace the wheels, guards, and other components in a matter of seconds.

A List of the Most Important Angle Grinder Features and Specifications

When purchasing an angle grinder, you will probably read the product description, and the specifications provided by the manufacturer. Here is some basic information that should help when you are analyzing the features of a particular tool:

  • Motor power – when analyzing the motor strength, you can look for the wattage, amp rating, voltage, or even horsepower in case of large units. The general rule is the bigger the number, the better.
  • Speed – you will find this information in the form of rotations per minute. A higher speed means the grinder works more quickly, but this ultimately depends on your performance. You can also choose between single or variable speeds.
  • Handle – the handle needs to be comfortable, which is why rubber grip is a must. Additionally, the side handle should have multiple positions to enable optimal control.
  • Wheel diameter – the common size is 4.5 inches, and it should be enough for most projects, but you can go with bigger wheels, too.
  • Replacing wheels and guards – consider whether replacing these two components is easy. The chances are you may have to buy additional wheels to improve the versatility of the unit. As for the guards, the replacement can either be tool-free, or you should get the wrench to replace them.
  • Safety features – these include overload protection, as well as kickback safety features for automatic-turn off in case of a jam.

Some other specifications you want to consider include dimensions, weight, cord length, battery life, etc.

Types of Angle Grinders According to Power Source

When it comes to a power source, angle grinders can operate by using the following:

  • Electricity
  • Gas
  • Air compressor
  • Battery

Each of the mentioned types has its pros and cons, which we will check out in the section below.

  • Electric Angle Grinders

    Electric grinders use electricity, and all you need to do is plug them into a power socket. As soon as you do that, they will be ready to run, and they will have unlimited runtime. Although they will automatically stop if there is a power outage, and you won’t be able to use them until the power comes back.

    These grinders are among the most frequently used, and the most popular among users, especially for home improvement projects. Their price is usually affordable, and they are fairly easy to use. However, you depend on the position of the power outlet, as well as the cord length. Aside from the ease of use, their great benefit is that they can pack a lot of power, especially when compared to battery-operated grinders.


    • Easy to start
    • Unlimited operating time
    • They can be very powerful


    • Can’t work if there is no electricity
    • Limited cord length
  • Gas Angle Grinders

    It is important not to get confused because these grinders operate on gasoline and not actual propane or natural gas. You will have to use tanks to run them, and that can make them heavy, which limits their operability. On the plus side, they can offer extreme amounts of power, which makes them suitable for heavy-duty tasks.

    Gasoline angle grinders work as long as there is fuel in the tank. That means you will need to refill the tank regularly and monitor the level of available fuel.


    • Suitable for heavy-duty tasks
    • Extremely powerful
    • A decent level of portability


    • Can get quite heavy
    • You need to refill the tank regularly
  • Pneumatic Angle Grinders

    If you have ever been in a professional workshop, the chances are you’ve noticed an air compressor powering one or more power tools. These grinders use air pressure to operate, and they can have a long runtime.  However, their power depends on the air compressor you buy. Compressors of inadequate quality may compromise the performance of the grinder, and limit its capabilities.

    Additionally, the price might not be your best friend because you will essentially be buying two tools instead of one. However, if you have multiple tools that your compressor would run, it may be a smart investment.

    • A good choice for big workshops and garages with multiple tools
    • Extended runtime


    • The power depends on the quality of both the grinder and the compressor
    • It can be expensive

    Be sure to read our editors picks for the best air compressors on the market!

  • Battery-Powered Angle Grinders

    Battery-powered grinders are essentially a subcategory of electric grinders. They use the battery to operate, but they require a power outlet to charge. The runtime depends on battery power, and you may encounter units that won’t last for more than an hour or so.

    Furthermore, even the most powerful battery can’t be as strong as an electric or gas-powered tool. Batteries do have many advantages, including the fact that they keep the device light, and you can take them to any location.

    • Excellent portability
    • Easy to maneuver
    • A lightweight device


    • Don’t expect it to be too powerful
    • Restricted runtime

Cordless Angle Grinder VS. Corded

Another big decision you will have to make is whether you want your grinder to be corded or cordless. Each option comes with its advantages, and you can check them out below.

cordless angle grinder vs corded

  • Cordless Angle Grinder

    Its biggest advantage is described in the name. The fact that it doesn’t contain a cord makes it incredibly portable and easy to maneuver. You can take these tools to any location, and you do not depend on electricity. However, you will need to charge the battery or secure an alternative power source (like gasoline).

    If you stick to batteries, the chances are you cannot expect plenty of power, or at least not as much as in corded tools. With cordless angle grinders, it is all about being lightweight and compact, and they can be a great choice if those characteristics matter to you.

    • Lightweight and small
    • Easy to operate and use on the go
    • No limitations on where you can use it


    • Restricted power
  • Corded Angle Grinder

    These grinders come with a cord, and they require electricity to run. That means you depend on an available power outlet near you.  While that may limit your maneuvering and the tool’s portability, there are valid reasons why you should consider corded tools.

    For starters, they can be more powerful than their cordless counterparts. That makes them suitable for heavy-duty and demanding projects and applications. Also, they are easy to use, and they are often packed with useful features, such as variable speed.


    • Very powerful
    • Suitable for demanding applications
    • Extremely versatile


    • You depend on available power outlets

Single Speed VS. Variable Speed Angle Grinder

When it comes to speed adjustment, we can differ in two angle grinder types:

  • Single-speed grinders
  • Variable speed grinders

A grinder that operates at a single velocity may be suitable for beginners because they do not have to go through the trouble of adjusting the speed. However, since these tools usually operate at high speed, that means it will take some time to get used to working it. In the beginning, you may face a lot of waste, but that should reduce as you become better.

On the other hand, variable speed grinders offer you the choice to pick between different velocities. It depends on the model, but the basic condition is to have at least two different speeds. The beginners might appreciate these units, too, especially because they allow you to choose the desired speed and stick to it while working.

When Is Variable Speed Important in an Angle Grinder?

An angle grinder with variable speed can be important in several situations. These include: The single default speed is too high for your preference or plans with the grinder. You need low-speed settings for finishing or brushing.

High speeds may lead to a lot of waste, and the option to adjust the velocity gives you the necessary freedom to work at the desired pace. With the help of the abovementioned points, we come to a simple conclusion. Variable speeds are critical when you are looking for extra versatility from your grinder.

Cut Off Tool VS. Angle Grinder

angle grinder vs cut off tool
Are you confused regarding the difference between these two tool types? In that case, you should check out our quick comparison guide below:

  • Versatility. You can’t say that cut-off tools are versatile since their primary use is cutting materials. On the other hand, you can use grinders for cutting, grinding, polishing, and sharpening, although they may require different wheels to handle those operations.
  • Ease of use. You can operate cut-off tools with a single hand, but with angle grinders, you use two hands to keep the optimal control level. The good news is that means they provide more consistent performance.
  • Types and sizes. You can choose various types of both tools, including cordless and corded variants. Cut-off tools are somewhat smaller in general, but you can also find compact grinders suitable for hard to reach places.
  • Safety. Both devices are as safe as power tools can be. As long as you follow the instructions, and wear protective equipment, you shouldn’t be worried.
    Price. Cut-off tools might be a bit cheaper, but angle grinders have excellent versatility and provide better value for money.

Angle Grinder Accessories

While you should keep your focus on the main tool, you should also set aside some time to consider the available accessories. Let’s take a look at some of the most commonly purchased accessory pieces for angle grinders:

  • Safety glasses – personal protection is imperative when using power tools, and safety glasses should be an essential piece of your gear. There will be flying particles when you are operating the grinder, and glasses will keep your eye protected.
  • Rim blade – if stone, porcelain, granite, or glass are among the materials you plan to cut with your grinder, you will need a rim diamond masonry blade.
  • Storage box – you might want to purchase a beautiful case where you would store your grinder. It is the perfect way of extending its longevity, especially if you do not use it frequently.

Angle Grinder Wheel Types & Uses

A grinding wheel is an abrasive component usually made of steel or aluminum. You can choose between several wheel types, and we are listing them below:

  • Straight grinding wheels – they are the most frequent choice for corded anglers. They are great for working on cylindrical surfaces and performing centerless operations. The power varies depending on the size.
  • Tapered grinding wheels – these are also straight, but they are tapered on the outside toward the component’s center. That makes them stronger and suitable for heavy loads.
  • Cylinder wheel – the surface of this wheel is wide and long. You can find them in spindle grinders, and the actual grinding process is done with the ending of the component’s face.
  • Dish cup – you can use this for cutter and jig grinding. These wheels are thin, which is why you can grind in slot and crevices.
  • Straight cup – they secure additional radial grinding surface, which can come in handy for many users.
  • Diamond grinding wheels – these are suitable for strong materials like gemstones, concrete, and carbide.
  • Saucer grinding wheels – another example of a durable wheel for heavy-duty projects, such as grinding twist drills.

FAQs & Answers

  • Q: What is an angle grinder?
    A: An angle grinder is a versatile power tool used for abrasive cutting (grinding) and polishing. Potential uses include, but are not limited to cutting tile, mortar, and pavers, removing loose paint, sharpening blades, and grinding steel.
  • Q: Which is better – 4.5 VS 5 angle grinder?
    A: The most common grinder wheel size is 4.5 inches in diameter. These tools are versatile while keeping their compact size, and suitability to reach tricky areas.
    On the other hand, 5-inch grinders can be a great choice if you plan on handling large projects and making deeper cuts.
  • Q: Why do I need an angle grinder?
    A: If you are wondering about angle grinder uses, this tool is very versatile. Some of the most common applications include cutting and grinding metal, pavers, tiles, bricks, as well as sharpening tool edges.
