1. DEWALT DWE402 Angle Grinder Tool – Best corded 4 1/2 angle grinder
- Weight: 6.2 pounds
- Voltage: 120V
- Horsepower: 1.8
- Dimensions: 15.63 x 5.94 x 4.81 inches
- Speed: 11,000 RPM
- Size: 4-½ inch
DEWALT DWE402 is the best corded angle grinder for all your home fixing jobs or DIY projects. This grinder boasts a popular disc size of 4 ½ inches, which fits grinding discs from 100mm to 115mm.
Additionally, this item runs on an 11-amp electric motor with a maximum rotating speed of 11,000 RPM, delivering the best power to weight/size ratio among many counterparts on the market.
The first reason I included the DWE402 on my top list is that it packs safety features to protect you from severe injuries while using a powerful and fast tool like angle grinders.
First, this grinder uses a Paddle Switch with no lock-on instead of a sliding on-off switch like cheap items, preventing accidental starting accidents.
Second, the 360o handguard with a single rotation action protects your hands from injuries, no matter you are left-handed or right-handed.
Convenience is another factor when picking up a cutting tool for non-professional purposes. The newly ergonomic handle design lets you easily control and maneuver the tool, especially when dealing with odd-shaped or small cutting areas.
If you need to switch from a large wheel to a smaller one for polishing a small space, the Quick-Change Wheel Release allows you to do it in a few seconds without special tools. The auto-off brushes will force the motor to stop in this case to avoid damages.
What should be improved on this electric grinder? It weighs 6.2 pounds, which is slightly bulky for an average person to use for an extended period.
- Best power to weight/size ratio
- Pack with various safety features: Paddle Switch
- Change wheels with no tools with the Quick-Change Wheel Release
- 3-year limited warranty
- Might be a bit heavy for new users

Makita 9557PBX1 is another best 115mm corded angle grinder with a cheaper price tag that you can consider when pursuing your DIY hobby. It is less potent than the previous DEWALT DWE402 (7.5 amps versus 11 amps) but much lighter with a weight of only 4.5 pounds. Thus, you can control and maneuver it for hours with no arm and hand fatigues.
How about its cutting efficiency?
Since this best Makita grinder comes with a General-Purpose Turbo Rim diamond blade, you can use it for concrete cutting or cutting other materials like tile, masonry, or granite.
Plus, you can cut any small areas with high accuracy, thanks to the metal gear housing that can rotate 90o left or right. You can utilize the available power supply with the AC/DC switch no matter where you work.

3. Bosch 1375A 4-½” Angle Grinder – Best budget
- Weight: 3.75 pounds
- Speed: 11,000 RPM
- Size: 4-½ inch
- Horsepower: 0.91
- Voltage: 120V
Bosch 1375A is a versatile choice for metal work, plumbers, vehicle fabricators, or any mechanic jobs that require the daily use of a grinder.
This tool comes with a portable weight of 3.75 pounds yet offers impressive power with a 6-amp motor and a maximum rotating speed of 11,000 RPM. Are there any other reasons that make this corded angle grinder good value for the money?
Dust and debris are unavoidable when you have to use grinders to handle industrial work applications daily. If left unresolved, these tiny particles can cause severe respiratory problems for you and nearby workers.
Besides using a vacuum cleaner to clean your working space, you might be happy to know that this Bosch angle grinder has a unique dust-free construction to protect the motor and internal electric parts. On the outside, it has a sealed switch to prevent generated debris from getting into the tool. On the inside, the epoxy-coated field windings keep all metal debris and abrasive dust from damaging the motor. Thus, you can maintain your work performance while extending its lifetime usage.
Another reason that makes this Bosch angle grinder a valuable choice for daily usage is that it inherits Bosch’s exclusive Service Minder Brush System. It means that the tool will automatically stop when its brushes need a replacement. According to the manufacturer, you should examine its brushes every two to six months to maintain the motor’s peak efficiency.

- Weight: 4.0 pounds

If this is your first angle grinder, and you don’t want to spend too much money on an expensive professional model, this Metabo grinder should be your perfect fit. This portable grinder offers the lowest price tag among the 6 remaining items on my list. Yet, it still includes essential features to help you get your jobs fast, safely, and efficiently.
You can share the Metabo G12SR4 with your coworkers or family members since it has a removable, forward-canted side handle that can be used for either left-handed or right-handed users. Thanks to the spindle lock, the disc or accessory changes are simple and easy, with no special tools needed.

5. DEWALT DWE43214NVS 5” – Best corded brushless angle grinder
- Weight: 6 pounds
- Size: 5 inch
- Speed: Variable speed
- Voltage: 120V
Angle grinders with a brushless motor like this 5-inch DEWALT one are pretty expensive, but they are worth every penny if you have to do grinding/cutting jobs every day and don’t want to lose much maintenance effort.
Since this brushless motor uses magnets instead of carbon wires for generating power, it is more powerful and produces less heating. Plus, this motor doesn’t require brush replacement like a brushed one.
This brushless DEWALT grinder has a disc size of 5 inches, which is compatible with all 125mm grinding wheels, just like the 1100W DWE4215. You can pick up an appropriate speed level to cut, grind, or sand many different materials depending on their hardness and cutting areas.
This corded 5-inch angle grinder also packs various safety features to protect you from possible injuries. For example, if you use this tool to cut hard materials, the electronic Kickback Brake will instantly stop the wheel and shut the motor off to keep the wheel from flying towards your hands. If there is a power outage, you will have to cycle the trigger on/off switch to restart the tool.
- High-efficient brushless motor
- Compatible with 125mm grinding wheels
- Various safety features
- No specific complaints
6. Makita GA7021 7″ Angle Grinder – Ideal for cutting thick material
- Weight: 15.4 pounds
- Size: 7 inch
- Speed: 6,600 RPM
- Voltage: 120V
The 6th candidate on my best-rated list is another grinder from Makita. Still featuring an AC/DC switch, the Makita GA7021 is suitable for small to medium-sized jobs. Let’s explore some differences between these two Makita angle grinders.
First, Makita GA7021 features a higher amperage of 15 amps and a bigger disc size of 7 inches, while the first Makita has a lower amperage of only 7.5 amps and a smaller disc size of 4 ½ inches. Thus, you can use this Makita grinder to deal with thick pieces of metal with ease.
Second, the maximum rotating speed of GA7021 is lower at 6,600RPM, while that of the remaining one is 11,00RPM, meaning that you will have to spend more time cutting materials with the exact sizing and hardness. The pros of this lower rotating speed are that your tool will stay cooler when working at higher speeds, thus avoiding risks of injury.
Third, the GA7021 is much heavier (10.4 pounds versus 4.5 pounds), which might be hard to control. Yet, I think that it is the price you have to pay for its stunning performance.
- Suitable for small to medium-sized jobs
- Extensive 7-inch discs for cutting thicker materials
- Come with no case

How To Choose The Best Corded Angle Grinder?
The speed measurement of corded angle grinders’ grinding wheel is RPM (in short for rotations per minute). It’s worth noting that the number listed by manufacturers is often the max speed in “no-load” settings or when the grinder is freely spinning without cutting or grinding any object.
Keep in mind that the quicker the wheel spins, the hotter it becomes. Moreover, never operate a wheel faster than its specified max speed, as it could break, resulting in serious injuries.
Smaller corded angle grinders’ rotational speeds vary between 5,000 and 11,000 RPM, and many models feature various speed controls to allow you to adjust the speed that fits your needs.
On the other hand, the max speeds of larger grinders are often lower, ranging between 5,000 and 8,000 RPM.
Angle grinders accommodating 4.5-inch or 5-inch wheels are the most popular among DIYers. They are compact enough to fit into tight locations (a majority are about 12 inches), yet powerful enough to do most common projects such as grinding, sharpening & sanding around the house, garage, and yard.
On the other hand, angle grinders with 7-inch or 9-inch wheels have more power, however, they’re also heavier & less maneuverable in confined locations.
Even though some DIYers may require these massive tools, especially if they carry out major renovation or auto repair tasks, these tools are typically used by professionals who require the biggest size and highest power when cutting through extremely hard materials including concrete & steel.
Corded angle grinders that have this feature offer you the option of increasing or decreasing their overall RPM speeds. If your projects involve polishing sensitive metals/surfaces, you should utilize tools with varying speeds to avoid damaging them.
The higher the amperage output that an angle grinder has, the heavier tasks it may handle. If you are new to this field, you should start with 7-8 amps before moving up to grinders with the normal 9-10 amps.
Heavy-duty operations, such as welding thick pipes, will necessitate angle grinders with higher amperage and bigger wheels.
Be cautious when choosing angle grinders based on their switch. Most welders prefer paddle ones as they can use their fingertips to turn the switch easily. Additionally, slide-up switches can also be a suitable option, particularly if you need to quickly turn the grinder off.
Because your corded angle grinders will be used on rough & potentially tough metal materials on a regular basis, it’s critical to choose a high-quality, durable angle grinder.
Long warranties are offered by the leading brands such as Dewalt to ensure that you can utilize the power tool & get good value for your money.
Dust buildup in a grinder’s internal parts can result in clogging over time, which can cause the machine’s motor to overheat and perhaps burn out. Dust accumulation might also cause the gears to wear out more quickly. Therefore, dust protection is essential, especially when you operate your grinder for extended periods of time.
Features that protect your grinder from dust, like a dust ejection mechanism and a seal, are available on some models. They help keep dust away from your power tool’s vents and its motor’s inner parts. These features increase the tool’s lifespan, reducing the need for replacement.
On a grinder, it’s critical to have a kickback brake since it ensures that the grinding disc is automatically halted when a pinch, bind-up, or stall is detected. Stopping the disc from spinning prevents the grinder from breaking free and kicking back at the operator, hence, avoiding serious damage.
Some grinder models include 2-stage triggers, which are another safety measure that helps to keep you safe. Before use, you must use the 2-stage trigger to deactivate the safety switch. This reduces the change of your grinder unintentionally starting while changing the wheel.
Angle grinders commonly rebound when they switch on since their motors are powerful and rapidly approaching the maximum speed. The power tool may bounce in your hands as a result of the recoil, posing a major injury risk.
The soft-start feature minimizes rebound during startup by lowering the power output at first and gradually increasing it till the power tool reaches its maximum speed.
The safety guard is the must-have feature for every angle grinder. It keeps your hand safe from the rotating disc, protects your face from debris and sparks, and minimizes surface damage when using the grinder in tight places.
There are either movable or fixed safeguards covering one-half of the grinding wheel, which allows you to see your work area.
- Moveable guards can be modified to suit your dominant hand & adjusted to shield you from flying sparks and debris. However, they can slip off your grinder if not properly fastened.
- Fixed guards are more durable and offer additional protection. Once adjusted, they are hard to fall off the grinder.
Thermal protection is beneficial to any motorized power tool. This safety feature, also known as a thermal cut-out, stops the engine when it reaches a maximum temperature. This protects the motor from overheating and possibly burning out.
After the grinder has cooled sufficiently, you can switch it on again to continue working.
