dcvbny Pneumatic Chamfering Tool Handheld, Mini Air-Powered Chamfering Machine Trimming, 45° Arc Corner with 1/4 Inch Air Inlet for Metal Wood Beveling Deburring (C&R Angle Blades)

It does great no burr. After parting something off deberring it was time consuming but not anymore.

Decent enough tool in build quality. Nothing new in its usage. Use to round edges or complete chamfers for a finished look. High reving to get the job done.

Great little tool . It’s loud but put a silencer on it and it’s a money maker

I've been a fabricator for 30 years but I can't get this tool to bevel correct. Tried on steel and aluminum but not consistent enough. Maybe it operator error lol.

This is cute little device with marginal documentation and works but does not do as heavy a cut as claimed.I tested it on some aluminum, mild steel and Delrin plastic... At 0.5mm it did a good job on the aluminum, and was somewhat OK on the steel. At 1.0mm it was barely functional on steel but basically not usable as it kept stalling out and gave a very ugly, rough cut. On the Aluminum it was a little better but still left a pretty rough finish. On the Delrin plastic it did very nicely. I did not try deeper cuts as I don't think I'd have gotten acceptable results. The surface finish of the chamfers was OK, not great, but probably would be acceptable for most applications. More usefully there were no obvious burrs on the corners, and it did a good job of removing burrs from prior operations.The documentation was a mixed bag at best... There was NO operating manual of any sort, just a single one-sided page with a well done parts diagram and list. The 'standard' parts like bearings and screws had both part numbers and descriptions that would allow easy replacing. EXCEPT for the two items most likely to need replacing - the inserts and the insert retaining screws...By going through the description pages for this item and the other variations on it, I was able to make a basic spec list, including possibly a partial description of the inserts....Bottom line, I would not recommend this for making high visibility chamfers but it is acceptable and useful as a deburring tool at shallow depths of cut.
