It works
Size: CB-M03H
I use it on a power tool as regular drill bits seem to not work to well with the plugs. They leak air. Doing it by hand is to hard

Doesn’t cut steel belts in tires to facilitate repair.

Pattern and roughness appropriate but still need to test
I haven't had a flat tire yet, so I also haven't had occasion to test these but they seem like great value for an extremely low price (especially versus a new tire.) I have handled them to try and gauge how quickly they'd smooth a hole, and they're rough / sharp and aggressive enough that I expect them to work quickly and well on not only tires, but on a variety of other materials. This pattern in particular should allow material to be shed and then passed backward pretty easily without clogging things up or slowing them down. If you've bothered to buy a patch kit for your tires, you really ought to have one of these around.
