8 Best Angle Grinders Budget & Pro Models For 2022

Last Updated on May 2022

What is the importance of angle grinders? In case you aren’t aware, angle grinders are among the most important welding tools that rarely miss in any serious metalworking shop. They are handheld devices that use their consumable discs to shape or cut metal, grind grooves, smooth a weld and remove rust from metal.

When TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding, the importance of working on clean, neat surfaces cannot be overstated. Angle grinders help you smooth the surfaces, thus saving you hours of labor.

But, as you might be aware, choosing the right one is no walk in the park, especially for first-time buyers. You will need to consider several factors, such as whether you want a cordless or corded grinder, the revolutions per minute (RPM), the disc size, type of speed, the switch, and others. Worry not, though, we have got you covered!

In this buyer’s guide, we will highlight some of the leading products in the market and everything you need to be on the look-out for when buying one for your metal works.

What are the Uses of an Angle Grinder?

Although you can use an angle grinder to perform several welding functions, the main uses are cutting metal and cleaning metal surfaces before and after welding. Read on to know more about the uses of these tools.

Cleaning the Metal before Welding

To prevent potentially detrimental weak welds, it is crucial to clean up surfaces that might have paint, grease, dirt, or rust before welding. Failure to clean the surface might lead to defects like porosity as the impurities more often than not contaminate the weld, making it weak over time. If you are dealing with a metal surface with grease, be sure to remove it with a solvent, then proceed to wipe it dry.

An angle grinder is your best friend when it comes to cleaning any metal surfaces to remove stubborn impurities as you prepare the metal for welding.

Cleaning the Weld

Whether you use TIG or MIG welding, it is not uncommon to leave unattractive and messy slag after welding, and you don’t want your recently welded surface looking untidy. While you could use a chipping hammer, sandpaper or a wire brush to clean up the surface, a grinder will get you better results quicker.

Here`s a tip to keep in mind when cleaning the weld: always hold the grinding disc completely flat on its face as you point it towards the metal to avoid cutting into the metal. Always keep an eye on the surface you are cleaning to ensure that you don’t eat into the clean metal.

 Cutting Metal

You don’t need to use a  plasma cutter when cutting out thin metal. You can use grinders provided you use the right cutting disc. An angle grinder can help you cut out thin metal surfaces without having to source for other equipment. It’s quick, and it can save you money.

Factors to Consider when Buying an Angle Grinder

We promised to help you out in your search for the best angle grinders around. Here`s a quick checklist of everything you need to consider as you look to select the tool that suits you best.

Corded or cordless

When it comes to portability, cordless machines are more preferred compared to their corded counterparts. With cordless angle grinders, you will need to use batteries since corded grinders rely on electric power to function. As a result, corded grinders are usually heavier than corded grinders.

Besides additional weight, these tools cannot manage high output as they rely on battery capacity to function. We recommend carrying an extra set of batteries if you plan on using a cordless angle grinder when outside your workshop. If you want higher power output, we recommend getting corded grinders as they can operate non-stop for long without having to recharge or make battery replacements.


Grinders with higher rotations per minute generate greater forces when in use. Remember, it is crucial to always check on the maximum RPM of a wheel before setting it in your grinder. Using discs with lower RPMs than your grinder might lead to the damage of your disc.

 Variable or Fixed Speed

Angle grinders with variable RPMs allow you to increase or reduce overall RPM speeds. Tools with variable speeds are preferable if you intend to use them to polish sensitive metals or surfaces. With a fixed speed tool, you will not be able to change the overall speed when welding.

Power/ Amperage

Angle grinders with high amperage can perform heavier projects than their counterparts with slightly lower power outputs. Beginners should try out 7-8 amps before upgrading to the standard amps of 9-10. Heavy projects like thick-pipe welding will require higher amperage and larger discs like the Makita GA7021, which has an output power of 15A.

Disc type

Angle grinders use different types of discs or wheels that include cutting discs, wire discs, flap discs, and grinding discs. Each wheel or disc performs different purposes, which means you might be required to interchange regularly depending on the type of welding job.

Cutting Discs are usually the thinnest and are used to cut metals. Compare this to Grinding discs, which are usually 5mm or thicker and are good for clearing slag or smoothening rough surfaces. Flap discs are appropriate for creating smoother surfaces as they are usually coated with sandpaper. Wire discs will help you polish your metal surface without eating into the metal. They help clean out sensitive surfaces.

Disc Size

As you can observe from the angle grinder review above, most grinders use discs with diameters of 4 ½ inches. The 4 ½ inch discs are appropriate because they are easy to fit into different surfaces, lightweight, and easy to use. Industrial angle grinders use discs as large as 9 inches depending on the type of surfaces.

Ease of Changing the Disc

When selecting grinders, we recommend settling for products that have easily interchangeable discs. Point to note, though, never change your wheel or disc when the power is on.


Welding is a fairly high-risk activity, especially if it is you lack the necessary experience. As such, we recommend taking adequate safety-enhancing measures. Always wear safety goggles and gloves when handling grinders. Check on items such as safety guards and switches when buying your preferred angle grinder. Heavy grinders usually come with increased risk of injuries, more so if the weight is above your handling capacity. Consider your overall strength and usability before settling on a particle product.

Type of Switch

Be careful when it comes to selecting grinders based on switch types. Paddle switches are usually turned on by the fingers, which is ideal for most welders. Slide up switches are also appropriate, especially if you want to turn your grinder off with ease.


A lighter angle grinder will be easy to carry around and use. Additionally, smaller dimensions are appropriate since they can be used on the smallest of surfaces. But, for industrial projects, you will need a larger tool, which will be heavier and more difficult to operate. First-timers or hobbyist welders should start with small-sized grinders as they build up experience and confidence.

Price and Warranties

Since your machine will be put to constant use on tough and potentially heavy metal surfaces, it is crucial to select a long-lasting, high-quality angle grinder. The best brands like the DeWalt DWE402 come with lengthy warranties that guarantee you will use the products and get value for your hard-earned cash.


Now that we have exhaustively discussed some of the best grinders in the market, the ball is in your court to select the one that suits you best. The ten angle grinders we have reviewed are proven performers and are guaranteed to serve you well in all your welding and metal fabricating activities.

As you buy your grinder, be sure to keep factors such as safety, switch types, RPMs, and wheel/disc types in mind as they will help you select the tool that best suits your needs. Also, if you choose to go the cordless way, remember always to carry an extra set of batteries when leaving the workshop.

We recommend the DeWalt DWE402 when it comes to corded grinders due to its high power output, 11000 RPM, and adequate safety enhancements. The Makita XAG04Z Fuel is our best cordless grinder pick as, it has an impressively high RPM of 8500, which is quite high for a cordless angle grinder.
