These tire repair reamers work great for plug/other type repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These tire repair reamers work great for plug/other type repairs. Gone are the days of manually fighting a hand reamer through rough rubber. This is an efficient, neat and clean way to prepare a tire for the repair. Will purchase again as needed.

Got what I paid for.
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
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.

These bits are great. We use them every day e when patching or plugging tires. Having multiple sizes helps us match the bit to the patch we use.

Easy on the hands
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These make it much easier to ream tires that have been punctured. It takes the stress off of your hands, forearms and elbows especially when you’re plugging higher ply tires.
