Here is our list of the 5 Best Angle Grinders
I wanted to include angle grinders with different budgets, as I understand some people may be strapped for cash and need something cheaper (I would recommend checking out the different types of angle grinders if you are unsure what angle grinder you actually need for your project).
- Features a standard-sized 4.5-inch disc that works well for most DIY home projects.
- Includes a handy carrying/storage case to keep components clean and in excellent condition.
- Has a 7.5 amp motor that’s strong enough to power through most plastic, wood, and cable.
- Utilizes paddle-switch operation for improved safety.
- Features a lock system for uninterrupted operation.
- Comes with a diamond cutting disc and several abrasive sanding wheels.
- Small size and design allow for precise cutting and sanding.
- The diamond cutting blade is capable of handling most materials with ease.
- The paddle-switch operation helps to ensure improved safety during use and is not a standard feature among most angle grinders.
- The included carrying case can rust in humid environments, making it difficult to close and open.
- It may not be powerful enough to handle thick, super-dense materials. Anything over an inch in thickness may require a larger, more powerful tool.
- The motor may overheat during extended use.
The Makita 4-1/2″ Paddle Switch Cut-Off/Angle Grinder is one of the pricier compact-sized corded angle grinders, but it’s also one of the most compatible. If you’re planning on using your future angle grinder for a variety of cutting, sanding, and polishing tasks, you could do a lot worse than this model.
It comes with a carrying case that unfortunately rusts when exposed to humid air. However, it also comes with a sturdy diamond blade, several abrasive sanding discs, and a 1-year warranty. But the best thing about this angle grinder might be its tiny size and ergonomic design.
At just over 12 pounds in weight, this angle grinder fits nicely into the hand and is fantastically easy to maneuver. Still, I wouldn’t use this grinder on thick pieces of stone or cement without worrying about burning out the motor.

The batteries get quite hot right after use and the charger will go into thermal delay to protect the packs.
For an angle grinder that’s battery operated, it was very similar in performance to a corded model. It has solid safety features with the anti-kickback and the brakes, which helps keep DIYers safe while working on projects.

A typical 6 amps of power, and not much else. This option can certainly appeal to those of you looking to slice through plastic or super-thin wood without dropping $100 on a single power tool.
However, this particular angle grinder can’t handle extended periods of usage and may begin to emit smoke or flames. Some of these grinders have even exploded during use, so this one might not check your box when it comes to safety.

Angle Grinder Buyer's Guide
Now that you’ve seen some of the best angle grinders, it’s time to get into the nitty-gritty of angle grinder shopping. After perusing the above grinders, you might think that you know everything there is to know about buying the optimal angle grinder.
And hey, who am I to say that you don’t? Still, it might be a good idea to check out this buying guide before investing your money into any old angle grinder. For example, you should probably take time to consider your preferred grinder’s:
- Disc Diameter
- Safety Features
Otherwise, you could end up with an angle grinder that just doesn’t cut it. And by it, I mean super-dense materials like stone, tile, or concrete. Of course, if you’re just looking for a handy tool for cutting softwoods or plastic, you might be just fine with an affordable, relatively low-power model.
Your angle grinder’s amps help to determine its power. Lower-wattage models might work well with softer materials and can be excellent sanding and polishing tools.
But if you’re hoping to grind down or cut through thick stone, marble, or ceramic, you’ll likely need an angle grinder with more amps. Standard angle grinders designed for DIY-loving homeowners tend to top-out at about 6 amps.
However, angle grinders that allow for higher amps can reach 11 or more, allowing for a greater surge of power. Essentially, the tougher the material you plan on grinding, cutting, or sanding, the more amps you’ll likely need.
Angle grinders come to life when they’re plugged into a power source and turned on. Electricity flowing into the power tool activates an internal motor which in turn spins the grinding wheel at a rapid pace.
Depending on the type of disc you have installed into the grinder, you can begin cutting, sanding, or grinding-down various materials. However, not all angle grinders are the same size. Larger models typically feature wider grinding wheels that work with equally large blades and discs.
Grinders with smaller disc diameters (4.5 inches or less) are easier to maneuver and work with, but they can lack in terms of cutting ability. You wouldn’t take a pony to a rodeo, would you? Well, you definitely would bring a 4.5-inch angle grinder wheel to a 2-inch stone paver party.
If you need to tackle heftier material, consider investing in a wider, thicker grinder that offers more heft. It might be slightly trickier to guide and use (especially if you’ve been skipping arm day at the gym), but you’re bound to enjoy the faster, safer, and generally easier cutting and grinding ability.
Do you already have a grinder in mind? Do ahead and take a look at it. If it doesn’t have a wheel guard, keep looking. Though some angle grinders feature specialized power-off features to help keep users safe, all angle grinders should at least have a safety wheel guard.
This important piece of hardware helps to keep your fingers, hands, and wrists safe from unanticipated shrapnel while cutting through materials. A paddle switch can also help ensure greater safety while using an angle grinder.
Of course, if you’re practicing proper safety techniques and wearing thick, protective gloves, you should be fine no matter which model you choose—As long as it has a wheel guard.
Angle Grinder FAQs
Becoming familiar with useful tools doesn’t happen overnight. Sometimes you just need a little supplemental information to help you make meaningful decisions and choose the best tools for the job. Allow these frequently asked questions (and corresponding answers) to ease your mind.
What size angle grinder should I buy?
The answer to this question depends on the type of project you’re working on. 4.5-inch angle grinders work well for most DIY home projects.

What is the best brand of angle grinder?
The two brands I highly recommend are Makita and DeWalt angle grinders. They both have solid warranties, a good reputation, and are well know for the tools they make.
How do I choose an angle grinder?
This can be a bit tricky, as you’ll need to weigh several factors and options when choosing an angle grinder. Still, the best thing to do when trying to decide among the hundreds of options is to consider your need. Why do you want to get an angle grinder? What do you intend to use it for?

What can you do with an angle grinder?
There are quite a few things you could do with an angle grinder. The multipurpose nature of an angle grinder is one of its best aspects. Still, it can be helpful to have a few examples.
Some of the most common projects or tasks that could benefit from having an angle grinder on-hand include:
- Cutting through a PVC pipe
- Slicing through tile and stone
- Grinding stone into desired angles or shapes
- Cutting through pavers
- Sand materials to make them softer

How many amps do I need in an angle grinder?
Once again, the answer to this question depends on what you intend to do with your angle grinder. If you’re planning on using it to cut through relatively soft and pliable materials, you can opt for an angle grinder with lower amps.
But if you’re working with tile, stone, and other dense materials, you may want to spend a little more for the higher-amp angle grinder. It’ll produce more power, allowing you to slice through tough materials without burning out your motor or moving at an agonizingly slow pace.
Whether you’re a welder, new homeowner, or something in between, angle grinders are handy devices that can help you slice through various materials with ease. Choosing one often comes down to deciding what size grinder you need, how powerful you’d like it to be, and how many safety features you’d like to have present in your new power tool.
Naturally, price and preference also play a role in the buying process, but practicality should be your top priority. Hopefully, this article sets you on the right path toward finding and acquiring the ideal angle grinder for your projects and work needs.
