    I've got a Rage2, I wouldn't recommend it, flimsy base and clamp, does the job but could be much better, I'd suggest a cold saw with a more solid frame/base/clamp or a horizontal bandsaw.

    It's only for thin wall pipe, up to about 50mm, and it's all the Minister for Finance (in this case me!) was prepared to shell out. Another $200 for the Makita with a smaller blade that are $200 each - get what you pay for of course, but too many other purchases preceded this (new compressor and Drill Press in the last 6 weeks knocks out $3500 with add ons like cabinet for compressor and compound tables for DP).

    I just wish I'd thought of the melted PC thing when I bought the Abrasion Saw late last year, but at least it was only $130 - Ozito, with a slow start which is great. This 355mm blade with no slow start has quite the kick to it!

    Just be a bit mindful what you try to cut.
    A bloke I know tried to cut some 6mm steel plate and he ended up destroying the motor and also the blade.
    Turns out it was not mild steel but some sort of hard steel alloy.

    Those Evolution blades doesn't like thick zinc coating, i have noticed that, blade gets dull very fast.

    But i have accidentally cut 2" stainless 316 rods with it without problem.

    My old Ridgid didn't like stainless materials at all, but had no any problems with zinc coating...

    Evolution has tungsten carbide teeths, i wonder why zinc is the one that makes problems?

    My thought was similar when I purchased it, don't use it enough to justify the extra $$, cheap blades, and have other tools to buy. I do still regret not paying the extra $200-$300 for something better.

    The Zinc probably has "galled" or partially melted onto the teeth this will make the teeth slippery and appear blunt. It should eventually come off.
    Maybe try cutting some small pieces of cast iron? The friability of the CI might remove the Zn

    If that was the case then surely the powder coating would melt well before the zinc, but it doesn't.

    Galling can happen at room temperature, it's a type of cold flow/smearing of a ductile metal over itself or a harder metal. It's also common with Al and especially Cu.

    I see, similar I suppose to what happens to brass & ally when filing.

    I have a block of wax for the blade from way back when I used to cut a lot of Al tube, so I wonder if that might prevent or mitigate the zinc from galling? Not that I have noticed it in the first dozen cuts

    Yep, that would help.

    Lets not go mixing up a thick zinc coating (i.e. hot dipped) as opposed to the much thinner, batch gal coating you have on steel like Duragal. That latter ain't going to gall or gum up on anything.

    .
    Yes just like that, there is virtually no heat as the blade cools before it runs through the cut again(thick materials and a blunt blade will generate heat though).
    Coolant will pose very little problems it wipes of easy and liquid hand soap removes any residue if you dont want to use a degreaser. Never had any problems with paint adhesion running coolant on my saw or effecting TIG welds that I've noticed(after cleaning).
    The bonus on leftovers/offcuts is no rust for months providing you dont wash it off.

    If your only going to cut thin wall tube get the highest TPI blades you can.

    A Bandsaw will not compete for speed against a drop saw, but even a small bandsaw has a large cut size capacity often a lot more than even a proper large coldcut saw( I dont call them dropsaws cold cut because they aint) Plus you can gang materials up to speed it up while you walk away

    I've got an AGP 14" saw and it works well. I have a horiz band saw as well, but rarely use that now.
    When I bought cut off saw a few years ago it was the cheapest around, but looking just then it seems it's around $750 - I wouldn't pay that for it.
