Best Cordless Angle Grinder Reviews

1. Dewalt DCG412B Cordless Angle Grinder

Our first product comes from DeWALT, a well-known company with a reputation for producing top-quality power tools. This model is of a slightly unusual design, boasting an ergonomic grip with a built-in trigger guard. Its appearance is certainly eye catching, but is there more to this model that may help make it the best battery-operated angle grinder for you?

Review

When you see the black and yellow design of DeWALT, then you know you are picking up a quality power tool. That’s true here since this is a model that comes packed with useful features.First off, it has been designed with comfort in mind. To that end, the front handle can be moved into two positions to find a grip you find comfortable. The rear grip is also ergonomically designed and includes a cool trigger-guard style design. In use, the tool has a quick-release button so that you can change discs or attachments safely and quickly.The 20-volt motor sounds powerful, but the tool can, in reality, only deliver a max of 8,000 RPM speed. That’s quite a bit below the 11,000 RPM that you would expect to find on a premium model. There is also no variable speed option, so when you press the trigger, the tool fires up to maximum revolutions instantly and stays there.All in all, this is a well-built tool with the solid construction you expect from DeWALT. It’s just a little let down that it is not quite reaching the premium performance of the other high-quality brands.

2. VonHaus Cordless Angle Grinder Set

While most cordless angle grinders are sold as a tool only, VonHaus have gone against the grain by presenting a complete kit. With a purchase, you’ll have a solid angle grinder tool, a battery, a charger, a carry bag, and even a free cutting disc; everything you just might need to get started all delivered in one convenient box!

Review

What you have here is an excellent angle grinder start kit that delivers phenomenal value for money. So, while many toolmakers will only sell you the angle grinder tool, here you get a full kit for a similar price others charge just for a tool.On top of that, it’s a decent and somewhat basic model, which means that the motor inside is nice and powerful with a 20 Volts max output that translates into 11,000 RPM. That is going to be enough to tackle a range of tasks. The handle is designed to dampen vibration and can be mounted on either side of the tool, making it comfortable for left and right-handed users.As a more basic model, it is missing some of the bells and whistles found on higher-end models. The lack of a quick-release, in particular, is a big omission, meaning you have to fiddle with a wrench to get the discs on and off. Nonetheless, the safety of the user has not been compromised as it is equipped with a two-stage safety trigger.

PROS

  • checkComplete kit
  • checkPowerful but lightweight
  • checkPrevents accidental starts
  • check100-minute charging time
  • checkUseful LED indicator lights

CONS

  • Handle only fits at 90 degrees angles
  • Wrench required to change discs

3. Makita XAG03Z Cordless Angle Grinder

Makita is another manufacturer with a well-earned reputation for producing high-end power tools. This model is from the pricier end of the options, but it is also packing a range of premium features.

Review

The stand out feature for us has to be the motor. It is of a high-quality brushless design that means it has a frictionless operation, making it both long-lasting and extremely powerful. It also means that more power can be squeezed out of a smaller motor, so this tool, despite its power, is very small, weighing in at barely six pounds.The power of the motor is also very intelligently controlled, as the tool will hold back full power until the cutting edge meets resistance.  This helps prolong battery and motor life while ensuring that power is always delivered exactly each time you need it.The only real downsides are that it neither comes with a battery nor a storage case. They are not deal breakers at all, but frankly, we were struggling to find the downsides to this very well-designed model.

PROS

  • checkAutomatic speed change technology
  • checkQuality motor
  • checkErgonomic design

CONS

  • Tool-only purchase

4. Bosch GWS18V-45 Cordless Angle Grinder

Our next product comes from Bosch, a manufacturer with a deserved reputation for producing extremely well-built power tools. This tool contains a number of the features that we look for in high-end angle grinders, so could this be the best one for you?

Review

This is a very good power tool, exactly what you would expect from Bosch. It is packing a number of useful features such as a quick-release button for fast and easy disc changes. It also has a comfortable ergonomic design, and the side mounted handle is designed to dampen vibration to make the tool easier to control.So far so good, but when you dig into the specs of the motor, it becomes a little less impressive. This model packs an 18-volt max output motor, which can only generate 10,000 RPM of spin speed. You’ll notice that both those numbers are a little below the power level generated by other premium-grade angle grinders.Bosch has probably done this to keep the weight and size down, and they have succeeded, as the tool only weighs about four pounds. So, it is light and small, but it’s also a little underpowered.

PROS

  • checkExtremely
  • checkBosch-quality construction
  • checkTool-free disc removal and replacement

CONS

  • Underpowered motor
  • No battery included

5. Hitachi G18DSLP4 Cordless Angle Grinder

We finish up with this model from Hitachi, which is small both in terms of product size but also in terms of cost. As the budget tool on the list, is it still able to deliver enough features to be a useful power tool while also keeping a few extra bucks in your pocket?

Review

As stated, this is a budget model and so it is lacking in a few features you would expect to find on higher end products. For example, there is no quick-release button, so a wrench must be used to change discs. This can be fiddly and time-consuming, especially when you are in the middle of a job. The side mounted handle is also very basic, as it has no vibration dampening abilities at all.That being said, this tool does deliver decent power, with an 18 Volt motor that although being less powerful than some other models, it is still able to kick out a decent level of power. It’s also very small, weighing in at four pounds and only being about 12 inches in length. That makes it particularly well suited for use in smaller, closed-in working environments.Additionally, this unit is loaded with safety features like an overcurrent protection system as well as a zero-voltage reset capability that will prevent unintentional starts once the battery is loaded.

PROS

  • checkVery light and compact
  • checkGood value for money
  • checkEasy and safe to use

CONS

  • Very basic design
  • No battery included
