WOW! These things are great! These are annular cutters like the mag drill takes but these are used in a hand held drill, drill press or mill instead. These are used on sheetmetal up to 1/4" thick plate. (cutters are taller than that, probably could cut up to 1/2" plate but...) Says up to 1/2" on plastics.
I needed a 16mm for some tooling I'm making so I got the metric set. I got mine here for $69.99:
https://www.mrmtool.com/Hougen-11077-RotaCut-Hole-Cutter-Kit--Metric_p_7468.html but many others sell for similar prices. (with this place, I got free shipping and NO sales tax!) Had them in 2 days too! These are all over amazon and ebay but you might have to pay ship or tax, do you homework!
I will be getting the S.A.E. set next, the small set is on sale for $75. They do have larger sets and combo sets that have the small and large. You can also buy each size separate if needed. (great if one gets damaged or worn out)
