Heavy-Duty Deburring Chamfer Tool with Sharp Tungsten Carbide Blades, Fast Hex Shank Deburr Drill Bit, External Burr Removal for Metal Rod Bolt Pipe 3D Printing PVC in 1/8" to 3/4" Diameter (3~19mm)

Great for chamfering saw cut bolts. When, and if it wares out I'd buy it again. Saved me lots of time.

Works perfectly, good quality steel and cutter. Great value

This is one of those tools that are like: "you know I wish I would have bought that cause it would have been much easier to use than a hand file in a tight space." Worked very well on multiple cut off studs. The nuts threaded right back on without needing additional filing help.

Does what it says well.

Effectively deburred the outside of the pipe that I intended to install a slip-on faucet onto. Guy at home depot told me that was an important step if the pipe has any sharp edges on the outside, it can cut the o-ring inside of slip-on faucets, preventing a proper seal. I attached this to my drill and it got the work done pretty fast. For a proper finish, I had to swivel the drill around a bit to prevent further sharp edges from forming from the deburring tool, which wasn't too hard.
