I can compare the Mannesmann with the mini-pipe cutter Corso 3-16 of scooters.
The part of scooter will cost more than double. The deburring tool in the head from the scooter is a 90 degree corner of a 1.5mm-sheet.
Since not even convinced me of integrated deburrer of scooter, I would recommend a normal 90 ° Hand deburrer.
The mechanics of the scooter is smoother and more massive than the Mannesmann. Ie equal to the difference in the price range
