All professional DIY workers have an electric grinder in their range of power tools, this is because it is the most universal tool in its fields of use.
However, in some cases, not everyone is able to use their power tools to their fullest potential, because sometimes they do not know how to replace worn discs or change their type of use.
First we need to understand how a grinder works, in a simple way we can summarize the grinder in a motor body that operates a rotating arm composed of the disk which as we know is removable and replaceable.


Disk replacement

 

before getting to the heart of the matter, let's pay attention to a detail that could really make the difference: safety.
Before starting, always check that you have unplugged the tool or removed the battery.
Once the first step has been completed, press the disc lock button which is generally found on the opposite side to the disc. Now all you have to do is use the key supplied with the grinder to unscrew the disc, obviously keeping the lock button pressed on the opposite side.
Once disassembled you can replace the disk and screw it back on by releasing the pressure on the locking button.
