Need to drill a 80mm hole in some thin galvanized metal, to make a smoker. Have always used "Starrett" in the past, but at £40 for something I will only use once is a bit steep. Cheap hole saws tend to be for wood and non ferrous, any alternatives or better makes, that will do the job? Thanks Nos

Jigsaw or drill mounted nibbler would be ideal for this size hole, assuming thickness as above.

Clamp it between two pieces of wood and drill through the wood.

Buy a cheaper hole saw.

Ive used loads of cheap holesaws. Even the Titan branded ones from screwfix work fine.

Thanks Hitch I do have some hole saws some "Wolf" ones and some cheap ones, have measured the thickness and its .80 mm, I would prefer to use a hole saw as it will be a neater job, so think I will give it a go when I get some flue pipe, thanks again. Nos

Tow pieces of wood work well especially if securely clamped , you get a neat hole and now distortion of the plate. Also done this at work when I snapped a mandril and dint have a spare , once you have a hole in a piece of wood with hole and clamp no need for mandril.

As long as its not the type where numerous ones fit onto a large back plate/mandrel at once.

Managed to cut a nice hole, had to use one of the cheapo stackable sets at about £4, I took my time with DW putting oil on all the time and stopping regularly to stop overheating, didn't think it was going to work, but it did, the saw of course now, would struggle to cut through warm butter :cb , but Iam happy :huray: now to get the pig in for smoking :scratch: :scratch: Nos
