    Default 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.

    Do these come with the changeable carbide tips like the one in the OP or they a tool steel insert?

    G/day Tony, here is a close up from one of the pics on the web page link above, looks like carbide inserts to 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.

    You could wrap it nicely and give it to the missus for mothers day, i'm sure she will let you use it

    The one I bought would do 3.5ish mm if you did it in several passes, worked really well for 5-10mm material before I dropped it and fractured the body of it.
