In-depth 9 Top Rated 6-Inch Angle Grinder Reviews
1. Makita 9566CV SJS™ High-Power – Best Corded 6″ Angle Grinder
Specs:
- Weight: 5.3 pounds
- Power source: Corded electric
- Speed: variable speed (4,000 – 9,000 RPM)
The Makita 9566CV is a good buy for professional and amateur users alike.
In terms of performance, the speed of this item is adjustable using a 5-stage variable speed control dial. Speed can go between 4,000 to as high as 9,000 RPM. The variable speed makes the Makita 9566CV perfect for stoneworking.
Spinning power is supplied by a high-efficiency 13-amp brushless motor.
The grinder itself has pretty good build quality. Most of the body is made from high-impact plastic. Parts that bear a lot of stress like the gear housing are made from solid metal. Rubber paddings are built along with the handle for extra grip and comfort.
Makita has been careful and added a lot of dust ingress protection features. The grinder won’t shut down even when sawdust and other particles are everywhere.
A special feature of the 9566CV is the Makita’s Super Joint System (SJC). Basically, if the grinding disc was to catch, the coil would relax and shut down the gears. By shutting off the grinder, the motor, gears, and the user are protected.
The only problem with the Makita 9566CV is that its power cord is a bit short. You’ll most likely have to bundle it up with an extension cord.
The grinder comes with a 1-year warranty for manufacturing defects and errors. However, according to quite a few customers, Makita’s warranty isn’t as good as many of its competitors.
Pros:
- Powerful motor
- Variable speed control
- Good build quality
- Special safety mechanism (Super Joint System)
Cons:
- Short power cord
- The warranty could be better
2. Makita GA6010Z with AC/DC Switch – The Runner up
Specs:
- Weight: 5 pounds
- Power source: Corded electric
- Speed: 10,000 RPM
From a brief glance, it would be hard to differentiate the Makita GA6010Z from the 9566CV. Most of their differences are under the hood.
Instead of a 13-amp motor, the GA6010Z comes with a 10.5-amp motor. Though the motor is less powerful, it doesn’t mean the GA6010Z is inferior. The motor runs cooler and is generally more power-efficient in comparison. Depending on the kind of power that you use, there’s a switch to let you change between AC and DC.
The recorded no-load speed of the GA6010Z is 10,000 RPM. There isn’t a variable speed control dial, unfortunately.
This model is just as well-built as the Makita 9566CV using a mixture of impact-resistant plastic, rubber, and metal. Notably, the soft rubber grip on the handle can reduce fatigue if you have to work for long periods. It is also sealed against dust contamination.
The power cord that it comes with is short. If you don’t have one yet, you should bundle it up with an extension cord.
Pros:
- Cool, efficient motor
- Decent performance
- Good build quality
- Can switch between AC and DC
Cons:
- No variable speed control dial
- Short power cord
3. DEWALT DWE43116 4-1/2-Inch to 6-Inch – Best price
Specs:
- Weight: 5.7 pounds
- Power source: Corded electric
- Speed: 9,000 RPM
The DEWALT DWE43116’s selling point is that it accepts 4½-inch, 5-inch, and 6-inch cutting discs. Smaller discs are better for small-scale, DIY projects. You can attach a 6-inch disc to it when you need the extra cutting power.
Packed inside the DWE43116 is a 13-amp motor, which has a rating of 9,000 RPM. At this speed, cutting through metal and stone shouldn’t be a problem. It doesn’t come with a speed control dial.
The grinding wheel is controlled by an e-Clutch system. If there’s a pinch or a stall, the clutch will engage and shut down the grinder to protect the motor and other components from damage. As long as the clutch works, you won’t be at risk of an overload.
Like every grinder, it has a dust protection system. DEWALT called it the “Dust Ejection System”. Any particle that enters the air intake will be shot back out into the environment.
At 5.7 pounds, the DEWALT DWE43116 is a relatively lightweight angle grinder. That, combined with a padded grip makes using it a comfortable, fatigue-free experience. There’s no complaint on my part about the build quality, either. It feels solid in the hand and will be able to withstand some abuse.
A problem with the DWE43116 is that it comes with a low-quality user manual. Not only it doesn’t offer a lot of useful information, it’s also very difficult to read.
Pros:
- Work with different disc sizes.
- Decent motor
- Good e-Clutch system
- Great build quality
Cons:
- Not a variable speed grinder
- Bad user manual
4. DEWALT FLEXVOLT DCG418X1 4-1/2-Inch to 6-Inch – Best Cordless Angle Grinder
Specs:
- Weight: 14 pounds
- Power source: Battery powered
- Speed: 9,000 RPM
If you’re looking for something more mobile and flexible, a 6-inch cordless angle grinder will fit the bill better than a corded one. In that case, try the DEWALT FLEXVOLT DCG418X1. It is one of the best cordless angle grinders out there.
Despite being battery-powered, the DCG418X1 has comparable performance to that of a corded one. It comes with a 13-amp motor, which is capable of achieving a no-load speed of around 9,000 RPM. The grinder accepts discs of 4½-inch to 6-inch.
DCG418X1 comes with trigger-based variable speed control. The harder you press it, the faster the wheel is going to spin.
It has an e-Clutch system to stop the motor when there’s a pinch or stall. In addition to the e-Clutch, you also get a Kickback Brake with the item. It applies force to the wheel to force it to stop spinning. The brake can stop a disc from full speed to zero in 1.5 seconds.
The battery is a 60V Lithium-ion cell. On a full charge, it can power the grinder for 30 minutes. Battery life is acceptable, but there are many grinders at the same price range that can last for up to an hour.
Pros:
- Good performance
- Trigger-based speed control
- Accepts many disc sizes
- Multiple safety mechanisms
Cons:
- Battery life could be better
5. MILWAUKEE 6 Inch Angle Grinder – Sturdy & Comfortable to hold
Specs:
- Weight: ~ 8 pounds
- Power source: Corded electric
- Speed: 9,000 RPM
Small and compact, the MILWAUKEE 6-inch angle grinder is a good one if you need something that you can carry around with you.
It comes with a standard 13-amp motor, which is capable of pulling a no-load speed of 9,000 RPM. The inclusion of the company’s Constant Power Technology™ ensures that the disc will always turn at high speed, even under load.
Like other grinders on this list, the MILWAUKEE grinder also has an electronic clutch to protect it from bind-ups. Overload protection is also featured.
The design of the grinder is sturdy and padding around the handle makes it comfortable enough to hold and use. However, the blade guard at the bottom doesn’t lock well into 180° position. Definitely a design flaw.
Pros:
- Compact
- Good performance
- Plenty of safety mechanisms
Cons:
- Flawed design
6. BOSCH GWS13-60 High-Performance – Cooling system for longer work time
Specs:
- Weight: 5.3 pounds
- Power source: Corded electric
- Speed: 9,300 RPM
The Bosch GWS13-60 delivers enough power to satisfy heavy-duty jobs.
Like most other grinders, it comes with a 13-amp motor and can pull a maximum no-load speed of 9,300 RPM. Notably, the motor has newer carbon brushes, which promises better longevity than the brushes on old motors.
It doesn’t have variable speed control, unfortunately.
To help the GWS13-60 perform heavier tasks without overheating, Bosch designed this grinder with a “direct motor cooling” design. It extends the length of time that the motor can perform under maximum load.
The grinder is built strong and has a two-position Vibration Control handle to the side. By limiting vibration, fatigue is reduced. The bottom burst-protection blade guard is adjustable.
Pros:
- High performance
- More durable carbon brush motor
- Cooling system allows for longer work time
- Fatigue-reducing design
Cons:
- Speed isn’t adjustable
7. Bosch 1806E 6-Inch Angle Grinder – Affordable price
Specs:
- Weight: 7.4 pounds
- Power source: Corded electric
- Speed: 9,300 RPM
The Bosch 1806E 6-inch angle grinder has a very similar design language to that of the Bosch GWS13-60. There are a couple of differences.
First, instead of a 13-amp motor, this one has a 12-amp unit. It still provides 9,300 RPM, but overall cutting power is a bit lesser than the GWS13-60. Furthermore, this model doesn’t have an active cooling system.
Design-wise, the Bosch 1806E (7.4 pounds) is slightly heavier than the GWS13-60 (5.3 pounds).
That’s about all of the differences between them. The 1806E still has a motor that’s engineered for maximum longevity, all of the safety mechanisms, and the distinct Vibration Control handle.
Pros:
- Good performance
- Lightweight
- Decent overall design
Cons:
- Doesn’t have a motor cooling system
8. Metabo 6″ Angle Grinders, Sliding Switch w/Lock – Powerful & Ergonomic
Specs:
- Weight: 6.54 pounds
- Power source: Corded electric
- Speed: 9,600 RPM
This Metabo 6-inch angle grinder comes with a 13.5-amp motor that can supply a maximum no-load speed of 9,600 RPM. It is one of the most powerful angle grinders on this list.
As it’s so powerful, it needs a safety system to keep it in check. The grinder comes with Metabo’s S-Automatic safety slip clutch in case of jams or kickbacks.
The best selling point of this angle grinder is its suite of electronics. You have an electronic soft-start system for a smoother startup. The grinding wheel is kept at high speed with an electronic speed stabilization system.
The overall design of the grinder is great. You can rotate the gear housing 90° for left-handed operation or when needed. It increases comfort significantly. The handle is also padded with soft rubber for better grip. There’s also an anti-vibration handle to keep the grinder running smoothly, too.
Pros:
- High performance
- Electronically controlled
- Ergonomics design
Cons:
- Pricey
9. Metabo WE14-150 Quick 6-Inch Angle Grinder – Featured with Electronic soft start
Specs:
- Weight: 6.25 pounds
- Power source: Corded electric
- Speed: 9,000 RPM
The Metabo WE14-150 150mm angle grinder is basically the lite version of the previous model. It has a 12.2-amp motor and can reach a no-load speed of 9,000 RPM. Keeping the wheel from spinning out of control is the S-Automatic brake system.
You will also get the full suite of electronic controls with this model, which includes an electronic speed stabilization system and an electronic startup system.
Aside from a few superficial differences, the design is the exact same as the previous model. That means the WE14-150 inherits all of its great ergonomics and comfort features.
Pros:
- Decent performance
- Electronically controlled
- Ergonomics design
- Soft start
Cons:
- Still quite pricey
