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.

Handy Tool for Frequent Flat Tire Repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
Good quality and easy to use. As someone involved in emergency services, we deal with flat tires often, and this tool has been really helpful. The bits are sharp, durable, and make the repair process quicker and cleaner. Great to keep on hand for regular use or in a roadside kit.
