A grinder is one of the most basic and simple power tools you’ll ever come across. Get a removable side handle, wrap inside a wheel guard a spinning arbor and a barrel handle, and you’ve got yourself a grinder. For all its simplicity, the grinder is quite a versatile tool.
Meanwhile, the best angle grinder is a grinder that’s a combination of finesse and raw power. It’s controlled aggression, almost. Your best bet when it comes to using grinders is in the metalworking industry.
Then again, grinding wheels can also work on stone and wood aside from metal. That’s what makes the grinder the all-purpose abrasive machine that it is. As for the angle grinder, it’s a kind of a grinder that’s a handheld power tool used for polishing, cutting, and (of course) grinding.
In regards to angle grinder reviews, the thing to keep in mind more than price versus value is overall effectiveness. Always look at the big picture. Watch out for the new four-and-a-half-inch models and how they fare with the bulkier traditional models.
Best Angle Grinder Reviews

In a sense, it’s the best hand grinder because it has a paddle switch that protects bearings and seals the motor from contamination. Its motor also has a no-load speed of 10,000 RPM, which is expected for a powerful 7.5 amp motor.
Its fresh take on the traditional body design can be seen by its barrel grip with a small circumference (about two-and-a-half inches) so that it’s an easier fit for your hand. What’s more, wheel changes have never been easier since features like the Makita spindle lock.
The package includes a wheel guard, flange, side handle, wrench, and grinding wheel. The company has even thrown in a one-year warranty for the device for good measure. What more can you want from this awesome Makita 9557PB? See our full review of the Makita 9557B.
2. Hitachi G12SR3 Angle Grinde

The edge for Hitachi is that with less amperage, you get less wear and tear, plus you don’t need the extra 1.5 amps for home improvement.
Hitachi also has a spindle lock that makes accessory and disc changes a breeze. It’s lightweight and compact as well, with a seven-and-seven-eighths grip perimeter to boot. Again, the main selling point for the 9557PB is its lifespan, which can be maintained with proper care, no abusiveness in usage, and the included auto-stop carbon brushes that make the 6-amp motor durable than most.

The DeWalt D28402K is arguably the best metal grinder of this collection of angle grinders thanks to its 10-amp AC/DC 11,000 RPM motor. It even addresses longevity fears from people who buy high-amperage power tools. It’s also unique in that it has its dust ejection system.
Its longevity is partly ensured because it cleans itself up when grinding materials down. The possibly tool-damaging debris that’s a given when it comes to grinding anything to dust is eliminated through its propriety dust ejection system that you won’t see in many other angle grinders (they instead have brushes and manually debris removal involved).
It’s the air intake vents where the dirt usually enters, but Dewalt D28402K is one of the few tools with a means to remove debris without taking it apart. See our full review of the Dewalt D28402k.

Again, Makita proves itself a winner by having two of its tools featured in this angle grinder review With that said, the 9564CV stakes its claim in the market with features like a powerful 12-amp motor, making it the most powerful grinder by default.
What’s more, the Makita 9564CV further solidifies its legacy with a variable speed control dial that allows you more flexibility in grinding. It’s unlike other grinders that can only go on one speed. It’s also a relatively compact tool for something so impactful, weighing in at 5.3 pounds.
If you’ve had startup problems in the past with other grinders, you won’t experience it with the 9564CV through its soft start feature. Instead of having a dust ejection system, the tool is completely sealed from debris. Check our

Why an Angle Grinder Should Matter to You?
If a workpiece has excess material on it that you can’t simply sand off with sandpaper (and it’d probably take too long to do anyway), then you can depend on the angle grinder to deal with it for you. It can also cut into a piece altogether, so it kind of doubles as a buzz saw or cutter in some cases. As many grinder reviews would take note, there are countless applications for grinders around the house and especially regarding industrial work.
They work either through the use of compressed air, petrol engine, or an electric motor, with the last item being the most common type. Invented in 1954 in Steinheiman der Murr by Ackermann + Schmitt, a German company, the angle grinder is one of the most dependable tools you’ll ever get.
Remember, the best die grinder is the one you need the most. Therefore, you should get angle grinders which ooze utility, like the ones with side handles for two-handed operation or adjustable guards.
How to Search for the Perfect Angle Grinder?
This is an excellent video to capture all of the basic stuff that you need to know about Angle Grinder. It’s 13 minutes, but it’s worth it!
Price versus Budget Value
The value in this context refers to how much you can get out of your grinder regarding successful operation. This depends on what you want to use it for. Regarding home improvement, usually, something like the Hitachi G12SR3 is enough. However, the best 4.5-inch angle grinder in this review is arguably the Makita 9564CV thanks to its multiple specs. Usually (although it doesn’t always follow), the more specs your tool has, the more value you’ll get out of it.
Then again, if you don’t necessarily need all 12-amps of power from a motor, it’s like buying a sports car in an area where traffic jams are rampant; you’re never going to use the full capabilities of your purchase. Don’t just go with the number of features, but also the quality of the features themselves. Do you need a dust ejection system or are you only using the power tool as an electronic substitute for the standard usage of sandpaper?
READ:Bosch 1380 Slim 7.5 Amp 4½-Inch Slim Grinder Review
Consider the safety features of your grinder. That’s where dust ejection systems, spindle locks, paddle switches, high overload protection, and other similar specs come in. This is safety in the context of protecting your investment by making it last longer and protecting you from harm.
The best 4.5 angle grinder is the safest one of the bunch. Your angle grinder should have special control features that help prevent you from being exposed to potential injuries. It should have things like an adjustable guard or methods of removal for dangerous byproducts.
It should also have a “dead man switch” handy that you can press during use in case you believe it’s become a danger to you or to itself. This way, you won’t end up accidentally starting the grinder and expose yourself to possibly life-threatening situations. Precautions must be taken when using these power tools regardless, which involve wearing protective clothing like helmets, goggles, and gloves. The safeness of the grinder regarding specs can only go so far in safeguarding you.
Make and Model
Trustworthy brands in the realm of angle grinding include DeWalt, Makita, and Hitachi. DeWalt is the brand that everyone is familiar of in the West, but Makita is already making a big name for itself, particularly in the angle grinder front. As for Hitachi, like the Nintendo Wii-U to powerhouses like Microsoft X-Box One and Sony PlayStation 4, it sits on the sidelines and has an ample share of the market with its respective niche. These are all good companies.
However, even the best companies don’t necessarily produce the best tool ever. It might go from the second-best company or the third-best company since the first-rate company has to concentrate on making quality power tools across the board.
Other considerations include power requirements, size, and model. Certain makes and models supply equipment for certain demands. With DeWalt, you’re always assured of an excellent product. However, sometimes, Makita has the better deal, and Hitachi has enough of good value for its offering since you don’t necessarily need industrial-strength angle grinding.
Disc Sizes and Specs
To compare models against each other, you should know their specs. What do they bring to the table? Makita 9564CV has the most powerful motor at 12-amps, followed by the 10-amp DeWalt D28402K, then the 7.5-amp Makita 9557PB, and finally the 6-amp Hitachi G12SR3. But that doesn’t necessarily mean the Makita 9564CV is the best, and the Hitachi G12SR3 is the worst angle grinder. You’re only looking at one spec and one aspect shared by all four models.
You need to look deeper, like the fact that the Makita offerings are all of the 4.5-inch variety regarding disc size, and the rest are more “traditional” grinders. Bigger discs might mean faster RPM and larger amps for motors might mean faster burnout from certain equipment.
The less abrasive the disc, the better it is for polishing. The more abrasive it is, the better it is for cutting and grinding the most abrasive of materials. Your choice should be made on a case-by-case basis, ultimately.
Choosing an angle grinder is best approached individually and in accordance to your needs. If you don’t need a truck, don’t buy a truck and buy a car instead. If you want to save more electricity, look at the wattage of the grinders, which can vary from 500 to 2,500 watts. Some models run on 230 volts and another run on 110 volts A/C. Angle grinders do have universal aspects to them, like the fact that they’re called angle drivers because the motor drives a geared head at a right angle.
The disc can be a thinner cut-off disc or an abrasive disc depending on your needs. All discs require replacement sometimes because as they get used more often, they will get worn. Certain models have safeguards against wear-and-tear, like the aforementioned anti-debris ejection system or other specs that avoid common mishaps associated with grinder usage.
Just how “abused” your grinder will be should depend on whether you want to use it for factory-type work with metal pieces or home improvement exercises and workshop-type activities.
The DeWalt D28402K gives the most value for your money with its powerful motor and longevity of usage that justifies its price point. Meanwhile, Makita’s offerings—the okay 9557PB and the incredible 9564CV—are both great angle grinders regarding making a good case for the four-and-a-half-inch grinders that are taking the market by storm.
Finally, the Hitachi G12SR3 is an enduring budget offering for most home improvement needs, although it falls short on specs when it comes to heavy-duty metalworking, for example. At any rate, it’s a tie between the self-maintaining DeWalt D28402K and the powerful 12-amp metal grinder Makita 9564CV with its anti-damage features.
