    Looks like they are only available in Australia. Perhaps our Aussie mates can chime in.

    Looks like refined pipe clamps.

    Look like woodworking clamps to me with that small beam and those thin cast clamping surfaces. I'm sure they're fine for thin stuff like gauge-thickness material, but so are any other light-duty clamps. They'd have no place in my shop.

    I think they have a place but not sure how far I would go to get them. I have a couple sets of 10$ ones on 3/4 pipe, on occasion they have their place and would replace them if they were lost tomorrow. I dont expect them to be brutal. I got one like the top one from my neighbor the other day, it had a particular reach I needed.

    Re: Excision Clamps

    We like Piher clamps over here for steelwork




    They look similar, but the Piher clamps are really quite beefy. The main backbone is 35x8mm for the medium strength version and I've never seen it bend visibly unlike Bessey F clamps.

    I like a heavy duty classic F clamp design though.

    I saw and played with some Piher clamps a couple years ago at Fabtech. They really were beefy and felt very solid and strong.

    Re: Excision Clamps

    The only thing I don't like about the Piher design is the screw itself. I have destroyed one of my maxipress clamp screws on jig work while pre-setting a bend in 50x50x3 stainless square tube. Literally tightening the clamp up as hard as I possibly can.
    After about 200 operations the screw now feels notchy and galled. It was brand new before I started the job. In retrospect these clamps were not designed for this sort of work.
    I moved onto a Bessey HD type, it has twice the size of screw and I use a 3/8" ratchet to tighten it up. The backbone flexes a lot but never deforms and have done probably 500-600 pre-setting operations with it.

    Ya, I would think it would be rather obvious they are not the same as a Bessy in comparison. All this has a place.

    I too prefer the look of a classic Bessey F although the curved body of the clamp in your top pic looks sexy yet beefy.

    Thin back bar clamps scream "woodworking" to me.

    I know it's mostly a personal thing but I like my Besseys....



    but I will admit to having a pile of Stronghand clones.

    I will go sit in the corner now. LOL

    this is one of my bessey type clones, they're imports under Kennedy name and they're fully awesome. The 14mm hex means you can use a ratchet to tighten them. Like i say, you can get a good amount of spring in the backbone, but it doesn't deform permanently.
    I've used these alongside the Bessey SG30M and they're as good as each other... I think I like the Kennedy model better.

    @munkul these excision ones are 35x8mm too.

    Clamping force is 1200kg,. 1200kg=2645lbs

    That must be a copycat Munkul, probably one of many

    Nice spec for general purpose steelwork etc then Are you in Australia? It looks like an Aus brand and I can't see any importers for the UK anyways.

    Re: Excision Clamps

    The brand is made in Spain I think.

    I wonder how much clamping force a normal f-clamp 400x140mm has.? Just to compare.

    The hydraulic has 4000 pounds of clamping force. Seems like the beam must be fairly strong. Maybe strong enough for punching holes in wood. Lol.

    If they were reversible they would be cool but they are not. I use the clamps like that, the ones that use a 3/4” piece of pipe as the bar, and they are reversible it is great to open and hold open something that is shrinking too much as you are welding it.

    If I wasn't so.....crazy, I wouldn't try to act normal, and you would be afraid.

    Looks great.
    I use a mig gun and just tact the part in place.
    It is faster than a clamp.
