Review on TIDEWAY Woodworking Forstner Drill Bit - Premium Quality Wood Cutter by Darius Carraway

price! Wow! Cheap! I need one Forstner bit per project to cut a hole once to install a door latch in a 1/2 inch sheet of hard plastic. First tested on a piece of scrap 2x4. up to the specified diameter - 50mm. I used a drill press to work with the clamp. So if the midpoint is too flat, as another reviewer pointed out, it didn't affect my application. Now the caveat: 50mm is NOT 1-15/16". That's close, and maybe close enough, but 50mm is 1-31/32", which is 1/32" more than the advertised English fractional diameter. In my application it doesn't matter - it's close enough. But specifying the bit as 1 - 15/16" is a little clever.
