It makes to process of plugging a tire a lot faster. I think you need to use a drill with these. Unless you had a hand drill with a chuck to tighten down on the bits, you probably wouldn't be able to use like a t-handle because you couldn't pull the reamer bits out. Just in case you were thinking of keeping this in a roadside emergency kit. It turns probably a 30 minute job into a 5 minute job with a drill though. I attached a picture of the hole after I was done reaming with all 3 sizes up to the largest.

These work great.

These work great, and is much easier than a hand reamer. Quality seems good as well.
