Buying Guide

This part of the guide includes a comprehensive buying guide that will definitely help serious buyers that are looking for the best utilization for their money. We will highlight some essential factors of cordless angle driver, through which you can judge any driver if you are not at all satisfied with our reviews of products.  

 Let us look at some of the most important things to take into the account before purchasing your suitable cordless angle grinder.


The battery is considered as the heart of the cordless angle grinder, so this should be your primary focus. Coming long way over the last few years, Lithium-Ion battery is finally equipped enough to be taken seriously into consideration as a source of energy for a power tool. In many cases, you might have to buy an extra battery and its charger separately, which no doubt is very expensive. Still, the good thing is if you select a line of tools to stick with, like DeWalt or Makita, you can easily reuse the same batteries for your whole line of devices. We suggest you stick to the lithium-ion batteries between 18 and 20 volts; otherwise, you will run out of power quickly.


Generally, there are two types of cordless motors available in the market which are brushed or brushless motors. Specifically, the brushless motor has made many cordless tools much more influential while using less energy, resulting in extended battery life. Having brushless motors give you the edge of less or no friction, thus runs a lot cooler and generally last for a longer time than brushed motors. 

However, the unfortunate thing is that the brushless motors do not yet are widely used in the Lithium-ion battery, so you will need to check the packing to see if a model that you are interested in has a brushless motor.


Weight is another crucial factor that can alter your experience of using any product. There is no doubt that more weight or heavy tools will cause fatigue to set in much quicker than a lighter device, causing your hands to get tired and cramp. It can be very challenging to control or manoeuvre, leading to accidents. Don’t forget that battery also weights so you will need to try out a few tools in the market to see what is more comfortable and convenient for you.

Disk Size

Lastly, a disk size is also something that you should take into account. The size of the grinding disk or blade will determine the size of the job you can complete. Small size disk is for precision grinding, while the more oversized discs are for large surfaces. Mostly wheels of these tools are 4 ½ inches, which is around the largest size the motor can easily spin. It is big enough for most jobs around the house, and we also know a lot of professionals that use these wheels regularly, but still, you may find larger wheels on corded grinders if you really need them.


When acquiring a cordless angle grinder, we strongly recommend pickup up at least one additional battery to have as a backup. Two extra batteries are probably much better as grinding can take some time. If you previously have battery-powered power tools, you will probably try or attempt to get the same brand.

We really hope that you have enjoyed reading over these analyses and found a brand that suits you and indeed has helped you make a new addition to your workshop tools.
