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!

Tire plugging must-have
I have plugged two ties since buying this and it makes it incredibly easy! No more struggling to get the hand reamer in. Stick it in a drill and go to town. I start with smallest and work my way up
