Flange Wizard - 72800 FLANGE WIZARD Radius Marker Small

I bought this because the medium is abysmal at drawing small circles. The small one measures in at 7.5 in length and effectively opens to about 8.5 - 9. In other words it will draw a 16-18 diameter circle without slipping out of a center punch mark. You can make a larger circle but its really not easy to do with how wide it needs to be open for that. I do like the medium as well, but just not for circles smaller than 12 diameter. They both claim to be pocket sized. I would say, sure you can fit it your pocket, but dont. They are sharp so youll likely poke a hole in your pocket and yourself if you do.

Does what its supposed to do

great tool, i use it all the time at work, when it was new it was pretty stiff but finally loosened up after a few times.

Must have tool
