When I first took the AVID POWER Angle Grinder out of the box, I was impressed by how solid and well-built it felt. The red finish looked sharp, and the auxiliary handle was easy to attach, giving me a good grip right away. I decided to test it on a few small home projects, cutting and grinding some metal scraps in my garage. The 7.5 Amp motor started up quickly and ran smoothly. I was surprised by how light the vibration was, which made it comfortable to hold even during the first few minutes of use.
Daily Use
Over the next few days, I used the grinder for different tasks around the house. I followed the advice to not run it for more than 30 minutes at a time and took breaks as recommended. This really helped prevent the tool from overheating. The included cutting wheels and grinding discs worked well on metal surfaces, and the flap disc was perfect for polishing and removing rust. I even tried using it on some stone tiles after buying a diamond disc separately, and it handled the job without any trouble.
