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.

Great value, easy to use, and do a great job.
Great for tire repair! It fits in any drill in a snap, so you are able to ream the hole out in a tire so you can patch and repair the tire. My shop used these all the time, and never had any issues with them. They hold up well, and do the trick for just about any size hole in a tire. Great buy!
