ICOOLInner-Outer Reamer for Copper PVC Pipe and soft steel Tubing,3/16 to 1-5/8inch in Diameter

To be fair, they don't say it will work on copper pipe, although I assumed when they stated it would work on metal pipe that would include copper, but nope. So, if you are looking for a reamer for copper, look elsewhere--this is worthless.

Handy reamer that’s easy to hold. Only used it on pvc so far but it worked great.

For ten bucks, you can’t beat it. Does the job on metal like copper and aluminum just fine.

It is not as sharp as description so I return it.As I mail it back with other item Amazon told me to do this, I didn't get the refund.It have been one week.

The tool is advertised to be able to deburr 1-5/8" copper. That diameter pipe doesn't fit in the tool. That's the main reason I purchased the tool. Aside from that, I like the size of the tool for better grip. It's about 3/4" taller than my Lenox reamer. We will see how long the blades last. I install a lot of boilers.
