3 Pack Tire Reamer Drill Bit, Multi Sizes, 3,4.5,6 mm

Works great thank you

These are inexpensive, but they work great. I use them to ream tires to repair. They have already paid for themselves. I highly recommend.

These are not going to help out in the field unless you have a drill, but do a much better and quicker job at home when you have a drill. Be aware these get crazy hot very quick.

I dropped my drill with the bit installed. It broke quite easily. It was a relatively inexpensive so I can't complain. A higher quality harder metal would have earned 5 stars.

They are sharp and effective on a cordless drill. Personally I use just the largest one for patching car tires as a full time mechanic but smaller applications Im sure the smaller ones would be useful.

Last for a while amazing

Bought to replace my reamer that bent, this one did a great job with no problems

I used to use ordinary metal drill bits to drill out the punctures in tires when repairing them. These are certainly better for that purpose. The sharp tip helps easily guide it through and the burr like cutting design leaves a much cleaner hole.
