10 Best Angle Grinders - Reviews
1. Bosch 1375A 4½-Inch Angle Grinder - Best Overall Pick
The Bosch 1375A gets top honors overall because it’s a great product at a great price. The 1375A is powerful, compact, and—weighing in at only 3.75 pounds—is incredibly lightweight. The low weight reduces fatigue and ensures a comfortable grip over long periods of use, even for inexperienced users.
The 1375A has a two-position side auxiliary handle, allowing for a natural grip whatever the position. An ergonomically designed top handle further ensures comfort and control over a range of different working positions.
This angle grinder comes with a variety of wheels, increasing versatility. Wheel changes are quick and easy with the included wrench, allowing you to switch between wood, masonry, or metal in seconds.
This model incorporates a powerful 6-amp motor into a compact, lightweight, and cost-effective design. It is ideal for vehicle fabrication, plumbing, metalwork, and other professional trades.
I chose a corded model over a cordless one because of power issues. Cordless models are very convenient. Unfortunately, they require a lot of power to operate. If you're working on a large project, it's going to be annoying to have to change out the batteries every six to ten minutes.
2. BLACK+DECKER BDEG400 Angle Grinder - Best for the Money
You can’t review power tools without reviewing Black & Decker, and once again, they don’t disappoint. The Black & Decker BDEG400 is a budget-friendly option with all the quality and reliability you have come to expect from Black & Decker.
The BDEG400 is equipped with most of the standard features you’d expect from higher-priced models. Easily adjustable side handles, a spindle lock, and a wheel guard come as standard, allowing user convenience and comfort.
Included with your angle grinder are a metal grinding wheel, spanner wrench, and a wheel guard. Even better, it comes with a very hard-wearing metal carry case to keep it all together.
You get a lot for your money with this budget-friendly option from Black & Decker. While you might be compromising a bit on power, you certainly won’t be compromising on quality or convenience.
3. DEWALT DCG413B 20V XR Angle Grinder - Premium Choice
Dewalt has brought another excellent product to us in the DCG413B angle grinder. This model is a top-end portable grinder that can handle anything from carpentry and plumbing to light masonry jobs. Rated to 9,000 RPM, watch it go from 0 to 9,000 RPM in less than a second for fast, efficient results.
Battery run-time isn’t bad. You can expect to get about 6 minutes of power per charge with high-level use. A quick-change wheel release and a tool-free guard adjustment make it a user-friendly machine and minimize interruption to workflow.
This model is an excellent angle grinder suitable for use by amateur enthusiasts and professionals alike.
4. Bosch GWS13-50VSP Angle Grinder
A higher-end model from Bosch, the GWS13-50VSP High-Performance Angle Grinder, is bigger, more powerful, and, of course, comes at a higher price. The product includes a backing flange, lock nut, spanner wrench, grinding guard, and vibration control side handles.
This model has variable speeds ranging from 2,800 RPM to 11,500 RPM. Lower speeds make it the best angle grinder for concrete polishing or working on granite. Meanwhile, the 13-amp motor (at high-speeds) allows it to power through metals and other materials.
This model is designed with an ergonomic paddle switch to allow a comfortable grip in a range of positions. Some people, however, prefer a standard trigger switch.
The Bosch GWS13-50VSP is a reliable and well-designed product. Variable speeds make it suitable for a range of jobs, from domestic DIY to light commercial work.
5. Makita XAG04Z 18V LXT Angle Grinder
Makita brings yet another outstanding power tool to the market with the XAG04Z 18V Cordless. If you’re unwilling to compromise on power or portability, then this is the best cordless angle grinder for you.
The 18-volt motor is powered by lithium-ion batteries, offering full portability and no troublesome cords to worry about. Also, the polymer construction makes it super lightweight to carry around and use just about anywhere.
If you’re worried that lightweight means less power, then you’ll be pleasantly surprised. The XAG04Z offers just as much torque as a corded model and is equally as robust.
This angle grinder comes with an INOX 36-grit grinding wheel, 36 Grit, 5-inch ultra-thin cut-off wheel, a lock nut wrench, 5-inch cut-off wheel guard, and a tool-less wheel guard. The brushless motor design eliminates carbon brushes and allows the motor to stay cooler. This ensures less maintenance and a longer-lasting machine.
Disc changing is easy, and the handle is adjustable to switch sides, depending on how you’re working. Another excellent feature is the automatic speed change technology that will adjust the torque while you work, so you don’t have to.
The Makita XAG04Z combines quality with convenience. It is packed full of features to enhance both user safety and comfort, while still giving a smooth, powerful performance in a cordless unit.
6. Metabo HPT G18ST Angle Grinder
If you’re looking to get some serious heavy-duty work done then, the Metabo HPT G18ST is the grinder for you. This electric angle grinder from Metabo is nothing short of a beast. Equipped with 15 amps of power, with plenty of mass and torque, this unit will power through concrete, metals, and stucco with ease.
It is a considerably heavier model than your standard 4½-inch grinder, so a certain degree of user experience is recommended. The upside, of course, is that the extra weight does most of the work for you.
In contrast to its heavy-duty exterior, the Metabo HPT has a soft start motor and is surprisingly quiet when running. The halved stator design increases cooling efficiency to protect the lifespan of the motor. Labyrinth style interior construction, meanwhile, prevents debris and dust from getting into the interior components, again increasing the lifespan of the unit.
The weight and design of the Metabo HPT optimize control and promote user confidence. It is created for heavy-duty service and designed with longevity in mind.
7. Makita 9557PBX1 Angle Grinder
We’re rounding off our angle grinder reviews with the Makita 9557PBX1. This has a high power output for a small size tool. A locking feature allows you to lock the machine in the on position to avoid fatigue. In addition, the small diameter barrel grip is comfortable to hold over longer periods of use.
The internal components are protected from dust and debris through an innovative labyrinth design. Together with the zig-zag varnish seals and thick coil wires, this promotes durability and extends the life of your angle grinder.
The Makita 9557PBX1 comes with a range of wheels for general purpose use as well as more specialized diamond wheels and grinding wheels. It offers plenty of power and smooth performance, and its compact design makes it ideal for tight spaces.
8. DEWALT DWE4011 Angle Grinder
We thought our angle grinder reviews wouldn’t be complete without another addition from Dewalt.
Because it is corded and plugged into the mains, it has more power and is, therefore, suitable for heavier duty tasks. That said, the design is still compact and lightweight enough to avoid user fatigue or discomfort. One handy feature allows you to lock the switch in the “on” position. This means you can use it for an extended period of time without tiring out your hands.
Convenience features include a quick-change wheel release, adjustable side handles for optimum positioning, and a one-touch guard. All are combined in a sleek, ergonomic design that provides maximum comfort over long periods of use.
9. PORTER-CABLE PCC761B 20V MAX Angle Grinder
The Porter-Cable 20V is our best budget angle grinder. The combination of portability and power makes it ideal for home renovations, auto repairs, and sharpening work tools. It packs just as much punch as comparable models from better-known brands, but without the price tag.
Under extremely heavy loads, the torque is compromised a bit. For this reason, we consider it more for domestic DIY and not a commercial-grade model. 8,500 RPM makes it suitable for just about anything around the house, though.
Unlike other models, it features a 3-position handle. This handle is unique and offers excellent maneuverability. With its lightweight and cordless design, it is an incredibly diverse addition to your tool-kit.
10. Ryobi P421 Angle Grinder
Our list for the budget-conscious DIY enthusiast is the Ryobi P421 6500. For a 4½-inch model, the Ryobi P421 6500 is surprisingly sturdy to hold. As with many cordless models, it does offer slightly less torque than equivalent electric models. What it lacks in power, however, it makes up for in maneuverability and ease of use.
Handy features include a side handle adjustable to three different positions for greater flexibility. The on-board pin wrench included with the tool allows you to replace grinder discs easily and quickly, meaning less interruption to your workflow.
We also like the rubberized grip near the trigger. The rubberized grip allows a comfortable grip and maximum control, even if your hands are oily or sweaty.
Battery run-time is a bit less than other comparable models. However, the Ryobi P421 6500 is compatible with a range of lithium-ion batteries from the Ryobi One+ Series. It shouldn’t be too hard to have a spare on hand.
We consider this a small, reliable, and surprisingly sturdy machine for the price.

Buyer’s Guide: Angling for the best angle grinder?
As with most items these days, you’re spoiled for choice with the extensive range of models on the market. This variety can be a blessing as well as a curse. Before you swipe the credit card, take a look at our buyer’s guide and angle grinder reviews to make sure you’re investing in the best angle grinder for you.
What is a Angle Grinder?
An angle grinder is a handheld power tool that uses high-speed blades to easily cut through concrete, brick, steel, metal, and other tough materials. Angle grinders can also be used for polishing and buffing, making them an excellent addition to any workshop space. Before you buy, it’s good to know the basics and what things to consider.
Consider the following before you buy...
Your budget always comes at the top of the list when you’re shopping around. There’s no point getting excited about a top-end machine if you just can’t afford it. That said, a top-end model might not be the best angle grinder for your needs.
Consider what you’ll be using it for the majority of the time, what materials you’ll be working on, and whether or not you need to prioritize portability or power. Knowing your budget will help you narrow down your search.
Corded or Cordless
Angle grinders are powered by either electric, compressed air, or gas.
Gas Powered: Gas-powered angle grinders are bigger, heavier, and are generally found in more industrial environments. Their portability and power make them suitable for a huge range of projects. They tend to be more challenging to handle, however and are not a great idea if you’re just starting out.
Compressed Air: Also known as pneumatic angle grinders, these models combine portability with lower weights, making for an easy-to-handle unit. They are generally less powerful than gas or electric models. For domestic DIY purposes, they are usually spot on.
Corded Electric: These plug into a standard domestic electrical socket. The benefit is a steady supply of power and usually a bit more punch. The downside, of course, is the reduced portability. You can buy extension cords to expand its reach, but you’re still more limited as to where you can use it than you are with a cordless model.
Power and wattage vary hugely between different models, and you can expect to find anything in the range of 500 to 2,500 watts, with amp ratings ranging from 4 to 15. Generally, the higher the power, the higher the price. You won’t need an industrial-sized motor to sharpen a few garden tools. Standard voltages will include 240volt, 110volt, and rechargeable 18volt for cordless models.
Similar to power, there’s a range of speeds available in domestic angle grinders, ranging from 5,000 to 7,500 RPM. Slower speed grinders generate less heat and are quieter to run. Unsurprisingly, faster speeds tend to pose a higher safety risk.
We always advise you to start at a slow speed and work your way up. Building speed slowly helps you to get a more precise cut as well as preventing juddering, vibrations, and overheating. The majority of models these days have variable speed adjustment, allowing you to perform a range of different tasks and work on different materials.
Also known as the wheel or the head, angle grinder discs commonly come in sizes ranging from 4½ inches up to 9 inches. Anything under 7 inches is usually fine for most domestic DIY jobs, giving the optimum balance of function and maneuverability.
Larger disc sizes are usually accompanied by a more powerful motor and achieve greater depths of cut on larger surface areas. Bigger is not necessarily better, and if precision work or polishing is more your thing, stick with a lightweight model with a small disc size for better maneuverability and precision detail.
If you’re shopping around for the best angle grinder, it pays to be familiar with other features you’ll hear mentioned frequently. While some are optional extras that you may or may not need, others are vital safety features. Optimum user comfort will ensure correct control of the tool at all times, offering a more efficient workflow, better results, and a higher level of user safety.
- Spindle Lock: Discs can be changed quickly and easily with a handy button that stops the spindle turning when the nut is being adjusted.
- Vacuum Attachment: Dust is the pet hate of many DIY enthusiasts. If you’re working in a confined space for several hours, proper dust management can help keep your air clean. A vacuum attachment is a handy feature that lets you connect your angle grinder directly to any household vacuum cleaner to allow the dust to be whisked away instantly.
- Moveable Side Handle: This increases versatility and lets you operate the grinder in a left-handed or right-handed position.
- Adjustable Disc Guard: A disc guard is an important safety feature that protects you from sparks or flying debris. The easy adjustment of the disc guard makes sure you’re protected no matter what position you’re working in.
- Anti-Vibration Handle: Over an extended period, vibrations from the angle grinder can cause fatigue and strain. Over time, this may result in repetitive strain injuries. By opting for a model with an ergonomic anti-vibration handle, you can help reduce the risk of fatigue and strain. Less fatigue also ensures you have optimum control of the machine throughout use.
