Pneumatic chamfering tool
I don't think I have a use for one of these, but maybe some of you do?

My Al ship builder BIL uses a small hand held router and standard WW carbide rounding bits to round over some of his corner TIG welds. He's typically welding 12 -16 mm plate and by the time he's finished it looks like a solid curved piece.

Nice tool if you have one but I`ll stick with my DIY one.
WW bits for ally and die grinder bits for steel. Good enough for me.

They use a triangular carbide insert.
If you’re doing a lot of heavy structural section that requires bevelling to weld, they are the ducks.. They are also very handy for a thousand other things that you don’t think of when you buy it. There was a thread on here about 18 months or so ago when they were first starting to appear more widely, someone bought one and did a bit of a show and tell on it.
The weak point is the guide bearing, as the youtube video suggests, the one it comes with will flog out relatively quickly, put a decent quality replacement on it, and keep a couple as spares.

This is a very small unit with a maximum chamfer of about 1mm so not really suitable for pre - weld preparation. The 45 degree angle is also not ideal.
