However, it’s the heaviest option on the list. At 13 pounds, the Makita 9557PBX1 forces you to take breaks to rest your arm in the middle of work.

Pros & Cons

3. Bosch 1375A Angle Grinders

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

A combination of affordability, lightness, and efficiency makes the Bosch 1375A.

The 6 AMP motor spins the wheel of the grinder at a no-load speed of 11,000 RPM. This means you can use it to fabricate metal, route, polish, and cut rebar or tile.

It’s also very lightweight at only 3 pounds, so you can use it for as long as you want without worrying about straining or fatiguing your wrist.

Its handling is made even easier thanks to the ergonomic grip, and two-position side handle.

Moreover, the lock-on switch keeps the tool running for you instead of you having to hold the button down.

Pros & Cons

  • Slim profile housing grip for easier handling

The Metabo WEV15-125 is the ideal angle grinder for cutting metal and much more.

For starters, it features a variable speed 13.5 AMP motor that maximizes its versatility. Especially that the speed ranges between 2,800 and up to 11,000 RPM.

This makes the Metabo WEV15-125 suitable for both casual DIY-ers and professionals.

Moreover, this unit comes with an improved design that maintains a suitable airflow that keeps the motor cool and extends its lifespan.

It would have been more efficient if it came at a lighter weight as it weighs a hefty 6.5 pounds.

But still, it has good ergonomics such as a tool-free disc change and guard adjustments.

5. Hitachi G12SQ Angle Grinder

Hitachi G12SR4 6.2-Amp 4-1/2-Inch Angle Grinder with 5 Abrasive Wheels (Discontinued by the Manufacturer)

The Hitachi G12SQ comes with a 7.4 AMP motor that enables you to operate the wheel of the grinder at speeds ranging between 2,600 and 5,000 RPM.

Having variable speeds is a great feature that isn’t available on most rivals, so it gives the Hitachi G12SQ an advantage.

Moreover, this unit is very lightweight, at only 3.5 pounds. This enables you to work for long periods of time without straining your wrist.

It also adds an element of maneuverability that enables you to finish work with higher precision.

Speaking of precision, low running speeds may deter some users from the Hitachi G12SQ. But if you’re looking to add a lot of details on a light-duty task, the slow spinning speeds would be another advantage.

Furthermore, the Hitachi G12SQ comes with a dual position handle and adjustable wheel guard that enable you to work with it from any angle.

There’s also an overload auto shut-off feature that protects your unit from being overworked or overheated.

Pros & Cons

The BLACK+DECKER BDEG400 isn’t the most powerful angle grinder out there, but it’s durable and gives you a bang for your buck.

The 6 AMP motor spins the wheel as fast as 10,000 RPM, so it’ll suit you for more than just the basic tasks.

Moreover, the hand-guard on the BLACK+DECKER BDEG400 can be locked into three positions to guarantee a safe operation. It also makes transportation and storage a lot easier.

At a super affordable price, this 4-1/2 angle grinder will help you finish light-duty to medium-duty tasks.

  • Motor isn’t good for high-volume jobs

Bottom Line:

The BLACK+DECKER BDEG400 is as affordable as a reliable angle grinder can get. It’s also quite durable and suits a wide variety of tasks, but not heavy-duty ones.

7. Meterk Electric Angle Grinder

Meterk Electric

The 6 AMP motor on the Meterk Electric can spin the wheel at a whopping no-load speed of 12,000 RPM.

It comes with auxiliary handles on both sides of the tool. This clever addition gives you more control over the cutting process to get the best results.

Furthermore, to protect the tool, there’s an outer coat that resists debris. And to protect you, there’s a protective cover that keeps you safe from any injuries or possible safety hazards.

The only downside to the Meterk Electric is that it’s a little heavy, so using it for extended periods may cause arm strain and fatigue.

Pros & Cons

  • Outer coat to protect the grinder from debris
  • 12000 RPM no-load speed
  • Amazing bang for your buck
  • 6-AMP motor is a little underpowered

Bottom Line:

Although the Meterk Electric operates at very impressive speeds, its motor is a little too weak to handle tougher materials or heavy-duty tasks smoothly.

How to Pick a Good Angle Grinder?

To get the most efficient angle grinder for your needs, you should consider some features first. These include:

Disc Size

The disc size indicates both the power of the tool and its capacity. The more powerful you want your angle grinder to be, the larger the disc should be.

This is applicable if you’re doing high-volume work and want smoother finishes in a shorter duration.

However, there are tasks that require precision and focus. These require smaller discs as they’re more practical to work around tighter angles and spaces.

Power Source

Your angle grinder will typically run on a battery or a cord connected to a power source.

If the idea of working in intermittent sessions and taking breaks in the middle suits you, then opt for a battery-powered model as they’d more flexible and maneuverable.

However, if you’re looking for continuous operation with no pauses in the middle, I’d recommend a corded model.


The speed at which your grinder’s wheel spins dictates the kind of material you can work with and cut through.

Most angle grinders have speeds ranging between 5,000 to 10,000 RPM (revolutions per minute). But just like disc sizes, different speeds are suitable for different types of work.

If you’re cutting through very tough materials, using high-speed grinders will help you finish the job more efficiently.

On softer materials, however, it may ruin the workpiece.

If you can get a variable-speed angle grinder, it’ll provide you with more versatility as you’ll be able to change the speed according to the task at hand.

Slow Start

I think this feature is essential when it comes to keeping your operation safe. Even if you’re looking for a grinder that reaches 10,000 RPM, it’s a lot better if it rises to that speed gradually.

Dust Sealed

Dust, debris, and fragments are bound to be everywhere around your workspace after you’re doing using an angle grinder.

And just like you have to protect yourself from them, there should be protective measures for your tool, and these are dust sealing and protection.

When your grinder is sealed against dust, it has a longer lifespan and becomes a lot more efficient.

Dust protection elements such as special seals or design prevent any dust from reaching the inner workings of the tool.

What Can You Do With an Angle Grinder?

An angle grinder can be used to finish many tasks. It depends on the speed at which the wheel spins and the strength of the motor.

For example, you can use your grinder to cut woods, metals, stone, tile, or even concrete.

Moreover, you can sharpen edges and tools, polish and clean metals, or remove mortar from bricks.

Final Thoughts

Buying the best angle grinder may not be a direct task, but once you learn what you’re looking for, you can narrow the options down to settle on the one that best suits your needs.

And if you’re looking for a reasonably-priced grinder that has reliable performance, I’d recommend the Metabo WP9-115.

If you’re looking for a budget-friendly choice, then go for the Bosch 1375A. It’s highly affordable yet still delivers superb performance.

The Makita 9557PBX1 is a good option that gives you value for the price, but it’s a little too heavy to be convenient for people who work for longer durations.

Finally, if you’re looking for the most powerful performance and budget isn’t an issue for you, opt for the Metabo WEV15-125.
