How We Picked

Top Angle grinder

After a lot of testing and research, I made this list of best angle grinders based on the following criteria:

Disc Size

Angle Grinding machines come in various sizes. The commonly available sizes are 4.5 and 7 inches. Small discs are pretty functional for fine work, while large discs are appropriate for heavy-duty jobs. You can opt for size according to the grinding, cutting, and precision of your work. We have chosen four devices with different disc sizes that work well with specific tasks. 

Power Source & Speed

There are typically two types of grinding devices as corded and cordless. My top pick is a cordless model because I wanted something more convenient and easy-going. They are portable angle grinders and hence you can take them anywhere. Corded versions are considered more powerful, but they are bound to stick to an electrical outlet consistently. 

Nevertheless, both are equally functional, and again, you can choose according to your preference and work. Plus, you can also consider speed rpm, which is the number of times a disc spins and the power it generates during operation.

Overall Features

Each grinder on this list has at least one unique feature. I have preferred models that are generally easy to operate and not very heavy. I have also considered ergonomics, comfortable grips, adjustable handles, and noise levels. 

Brand Reputation

I have paid more heed to the brands with a reputable online presence and honest customer base. You should always check online reviews, feedback, and the features of the product before buying. It depends on how you choose to spend your money, but a product should always provide value for your money. Therefore, do active research to avoid any horrible experience.

How We Tested

I had a lot of free time in my hands during the lockdown. So, I decided to utilize it in the best way possible by taking my tools and DIY understanding to another level. I reached out to a couple of brands, tried plenty of grinding devices, and continued my research. 

I liked several items but dropped the idea of buying after finding reviews of unhappy customers. After discussing with an artist friend, we decided to make 3-4 different categories and start our research accordingly. 

Going from corded to cordless, 2-7 inches disc sizes, fixed to variable speed, we went all out and approached well-reputed brands. We filtered this list into four final categories to present to you guys with the best-built and high-performance products.

Top Pick: Makita XAG04Z 18V LXT Lithium Brushless Angle Grinder

Best grinder for professionals
  • Great power
  • Well-built and sturdy material
  • Easy to use
  • Brushless motor to support prolonged working hours
  • Fairly noisy
  • Fiddly guards
  • It sells the battery separately

Makita XAG04Z is a portable and super convenient angle grinder for everyday small-mid level tasks around the house and garage. It features a brushless motor, ⅝ inch 11 spindle thread, 8,500 rpm, a robust paddle switch, automatic speed change, and active feedback sensing technology.

One of the many advantages of this apparatus is that it features a brushless motor. These motors don’t require frequent repairing and maintenance, plus they have the perks of enhanced efficiency, durable run-time, reduced noise, and heat.  Makita’s brushless motor is designed to deliver improved run-time that lasts up to 50% longer per charge. It enables the brushless motor to stay and run cooler for extended hours. In my opinion, it is a great plus for the functionality of a cordless item.

Its active feedback sensing technology (Aft) shuts the motor off if the rotation of the mounting wheel suddenly gets jammed. It boasts an automatic speed adjustment technology that changes the speed and torque according to requirements to deliver optimized performance.

There are some minor drawbacks that I would like to address. Firstly, the company sells the battery separately. You have to buy a separate Makita 18V battery. Secondly, it has lots of power to survive for days for intermittent use; it still drains the 3.0 or lower battery. I recommend using 5.0 or even a higher battery. 

Although this model is a bit expensive to get started with, the functionality outperformed my expectations. This product is too advanced from the old-era cordless devices. This Makita cordless grinder is a fantastic choice to add to your collection if you prefer a cordless and compact model that is easy to use.
