In-depth 7 Top Rated Variable Speed Angle Grinder Reviews

1. Metabo HPT G12VE Variable Speed 4-1/2-Inch – Best Variable Speed Grinder

Check Latest Price on Amazon

Specs:

  • Weight: 4.2 Pounds
  • Size: 4 ½ inch
  • Dimensions: 12.2 x 3.7 x 2.1 inches
  • Power source: Corded electric
  • Speed: 2,800 – 10,000 Rpm

Metabo is a trusted name in the angle grinder industry. One of their best sellers right now is the Metabo HPT G12VE.

In terms of performance, the HPT G12VE comes with a 12-amp, brushless motor. The motor offers a lot of torque and can attain a no-load speed of around 10,000 RPM. The speed can be variably adjusted between 2,800 RPM and 10,000 RPM.

The 12-amp motor is controlled by an inverter circuit. If your power supply is uneven, the circuit kicks in to regulate the current, ensuring smooth and uninterrupted performance. 

Additionally, like many other grinders, you get a number of safety mechanisms like kick-back protection and zero-voltage restart protection.

You can work the grinder using a paddle switch. A lock-off lever must be pushed down before you can depress the switch. For some people, the switch’s difficult to use.

The grinder is fairly lightweight at around 4 pounds. To reduce weight as much as possible, the body and side handle are made from plastic. Only the gear housing is made from metal. The handle is rubberized to provide a firmer, more comfortable grip.

Pros

  • Lightweight
  • 2,800-10,000 RPM variable speed adjustment
  • Multiple safety mechanisms

Cons

  • Not a good choice for those who aren’t fans of paddle switchs

2. DEWALT DWE43214NVS 5” – Best Corded Variable Speed Angle Grinder

Check Latest Price on Amazon

Specs:

  • Weight: 6 Pounds
  • Size: 5 inch
  • Dimensions: 16.89 x 6.1 x 5.12 inches
  • Power source: Corded electric
  • Speed: 2,200 – 10,500 RPM

The DEWALT DWE43214NVS is a 5 in. variable-speed electric angle grinder. Its small disc size means it is more suited for DIY or light-duty projects like wood-carving.

Cutting power is derived from the 13-amp electric motor. According to the manual, the maximum no-load value is 10,500 RPM. As the DWE43214NVS comes with a speed change dial, you can flexibly adjust its speed between 2,200 and 10,500 RPM.

The motor is completely brushless, so you don’t have to crack it open to change the brush every once in a while.

Safety features include Power-Loss Reset® tech, which can restart the grinder from zero-volt. If the drill shuts down unexpectedly or there’s a power outage, you can just press the ON/OFF button to restart it from zero-volt.

Electronic kick-back protection will kick in when it detects a pinch, stall, or bind-up. The in-built brake can stop a standard 5-inch (125mm) wheel in less than 2 seconds once it has kicked in.

Compared to the Metabo, the DEWALT DWE43214NVS is more elaborate. The body is made from yellow plastic with a rubberized handle section. Metal makes up the gear housing at the front. The whole package weighs around 6 pounds.

The power cord is 6 feet long, which is decent enough for an angle grinder.

Pros

  • Good-looking design
  • Low-maintenance motor
  • 2,200-10,500 RPM variable speed
  • Multiple safety mechanisms

Cons

  • Relatively heavy
  • Not the best choice for specialized heavy-duty jobs

3. BOSCH GWS13-50VSP – High no-load speed

Check Latest Price on Amazon

Specs:

  • Weight: 5.3 Pounds
  • Size: 5”
  • Dimensions: 12.5 x 2.75 x 2.75 inches
  • Power source: Corded Electric
  • Speed: 2,800 – 11,500 RPM

With a 13-amps motor and no-load speed around 11,500 RPM, this 5-inch grinder from Bosch can handle many different jobs. Take it into consideration if you need a powerful tool in the 5-inch disc size range.

The 13 amps motor, like we mentioned earlier, has a very high no-load speed of 11,500 RPM. Since it comes with a variable speed control dial, you can tune it down to a minimum of 2,800 RPM whenever you need it (great speed for polishing).

Notably, this grinder has a “direct-motor cooling” design. Supposedly, it can cool down the motor when it gets too hot, ensuring stable performance throughout. This is a very good feature to have in case of overload.

The design of the GWS13-50VSP is standard: plastic body, rubber handle, and metal housing. At 5.3 pounds, this model is more lightweight than the Bosch GWS 9-115s 115mm, which weighs about 6 pounds. Less weight means less fatigue when used for an extended time.

If you need something even more lightweight than that 5.3 pounds, try the smaller Bosch Professional Mini Grinder – GWS 7-115e. This one is only 4.1 pounds heavy and is quite compact with a flat head, making it highly suitable for work in cramped spaces. Note that the mini version only has a top no-load speed of around 11,000 RPM.

Pros

  • Powerful motor with a high no-load speed
  • 2,800-11,500 RPM variable speed
  • Can handle overload with direct-motor cooling design

Cons

  • Heavy and can induce hand fatigue

4. MAKITA 9565PCV

Check Latest Price on Amazon

Specs:

  • Weight: 5.3 pounds
  • Size: 5 inch
  • Dimensions: 6.5 x 15 x 5.5 inches
  • Power source: Corded electric
  • Speed: 2800 – 10,500 RPM

The MAKITA 9565PCV has a stronger motor than most angle grinders in the 5-inch range. Thanks to a 13-amp motor, this grinder can build up to a no-load speed of 10,500 RPM. Of course, the 9565PCV also comes with a speed adjusting dial that allows you to freely change the speed between 2,800 and 10,500 RPM.

One of the best selling points of this item (and just about any Makita grinder) is the patented Super Joint System (SJS). If the wheel is forced to a stop, the drive shaft will automatically slip. It protects the motor and gear from being damaged by a sudden stoppage.

The grinder also comes loaded with a variety of electronic control systems. You have a controller that maintains the wheel’s speed even when it’s under load, a controller for soft start-ups, and a current limiter to protect the grinder from overloads.

Design is basic with a plastic body, rubber handle, and metal housing for the gears. A vibration control handle is to the side of the grinder for greater comfort and control. 

Weighing around 5.3 pounds, it is quite heavy. Nonetheless, the ergonomics of the grinder is good enough that we haven’t found any complaints about fatigue for the 9565PCV thus far.

Compared to a close competitor, the Makita GA5040C 1400W 125mm grinder, the 9565PCV is a bit weaker. The GA5040C can go up to 11,000 RPM while this model is stuck at 10,500 RPM. In return, the 9565PCV is lighter and more affordable. 

Personally, I think that the features of both models are similar enough that the cheaper price of the 9565PCV will make it a more value purchase.

Pros

  • Powerful motor
  • 2,800-10,500 RPM variable speed
  • Electronic control system
  • Super Joint System protection

Cons

  • Design is quite dull

5. Metabo 5″ Variable Speed (WEV 1500-125 RT) – Strong performance

Check Latest Price on Amazon

Specs:

  • Weight: 5 pounds
  • Size: 5 inch
  • Dimensions: 15 x 5 x 5 inches
  • Power source: Corded electric
  • Speed: 3,500-11,000 RPM

You can pick up the Metabo WEV 1500-125 RT if you need a 5-inch angle grinder that can produce a lot of cutting power.

The 13.2-amp motor, combined with the speed adjustment system, can give you speed anywhere between 3,500 and 11,000 RPM. This speed is good enough to handle any cutting job that a 5-inch grinder can reasonably take up.

There is an auto-stop system within the motor. The moment there’s an issue such as an overload, it shuts down the motor to protect it.

Like other high-quality angle grinders, the Metabo WEV 1500-125 RT comes with kick-back protection and an electronic soft start system. It can also be restarted from zero-volt condition, as well.

Metabo did a great job designing this grinder. Both the handle and side handle are encased in rubber for a firmer, more comfortable grip. A portion of the body is made from plastic to reduce weight, but the gear housing and guard are cast from metal.

Weighing 5 pounds, it’s a pretty hefty grinder, but the ergonomics design balances it out.

Pros

  • Strong performance
  • 3,500-11,000 RPM variable speed
  • Excellent ergonomics design

Cons

  • A bit heavy

6. Makita XAG20Z 18V LXT BL 4-1/2”/ 5” – Best Cordless Variable Speed Angle Grinder

Check Latest Price on Amazon

Specs:

  • Weight: 5.7 Pounds
  • Size: 4 ½ – 5 inch
  • Dimensions: 7.9 x 13.9 x 5.4 inches
  • Power source: Battery Powered
  • Speed: 3,000 – 8,500 RPM

If mobility is important for you, check out the Makita XAG20Z variable speed control angle grinder. It’s a cordless one that runs on a battery instead of a power cord. So, as long as the battery’s charged up, you can work anywhere you want.

Because it runs on a battery, performance is weaker. In manual mode, the motor inside can drive the grinder from a low of 3,000 to a high of 8,500 RPM. Automatic speed change technology adjusts speed and torque during operation for optimum performance.

This motor is brushless, so it doesn’t require a lot of maintenance and can run cooler and more efficiently.

The grinder is still loaded with a number of safety systems. There is an active feedback-sensing tech that will shut off the motor if the wheel’s stopped suddenly. A controller flexibly regulates the grinder’s performance when it comes under load to give you the most optimum operation.

Overall design of the grinder is still the same as other Makita grinders. Only this time, there’s a big bump near the handle, which is where the battery is located.

Pros

  • Mobile design
  • Efficient performance
  • Numerous safety systems

Cons

  • Relatively low performance

7. Hoteche 4-1/2″ Electric Variable Speed – The cheapest

Check Latest Price on Amazon

Specs:

  • Weight: 4.2 pounds
  • Size: 4-1/2″
  • Dimensions: 15.2 x 4.9 x 4.1 inches
  • Power source: Corded Electric
  • Speed: 0-11,000 RPM (6 levels)

If you want an angle grinder for cheap, consider the Hotech 4½-inch. It’s a decent budget tool for DIY-ers and those who don’t need a pro-level grinder.

This Hoteche grinder comes with an 8-amp motor. It has a no-load speed on paper of up to 11,000 RPM. Real-life performance isn’t as high, but it’ll do for cutting wood and softer materials.

It is double-insulated to prevent electrocution and the motor has an auto-stop system.

The design is basic with a plastic body, rubberized handle, and metal housing. It’s a fairly lightweight grinder at 4.2 pounds, so you can use it without fearing fatigue.

Pros

  • Very affordable
  • 0-11,000 RPM variable speed
  • Lightweight and compact

Cons

  • Performance is quite low in real life

3. Do all angle grinders have variable speed?

The answer is NO. Many only offer a single speed. These typically are larger grinders with wheel diameters around 7 inch to 9 inch. Since they’re heavier, bulkier, and are expected to perform heavy-duty tasks, having only one speed doesn’t hurt too much.

Versatility is its best selling point. You can use it for many different kinds of tasks. So long as the job isn’t too heavy, your grinder will always be able to work its magic.
