I got tired of changing disks to cutting wheels to grinding wheels etc, while working on a metal fab project so I went and bought several Harbor Freight Ones for about $15 each. Each has a different accessory and saves a lot of time and effort.

I figured I could throw them away and not sweat $15. They have been used and abused for well over 10 years now.

The new ones have crap Switches. Sneeze and they pop loose and you have to latch them again. I would prefer a simple trigger or a switch that stays on no matter what. Instead they have millennial switches. They quit working when you need them to do their job the most.
