NAVACNTD28 Copper Tubing Deburrer | Pipe Deburring Tool | Replaceable Deburring Blade | 2 Spare Blades Included | 1 Year Warranty

It does what it says. They are all pretty much the same that look like this, just different colors.

It does what it says it will do and that's deburr holes. Be aware the body is plastic but the blade is definitely a bit longer and more robust than other generic blades. The unit came with two additional blades stored in the handle as well which I appreciate.
