Cutting sheetmetal trailer skin - any ideas/suggestions?

[Mike0123]

So as a follow up to my original post on this subject
https://www.spyderlovers.com/forums/...tach-the-metal
I am wondering if anyone has heard of a flush trim bit for a router or laminate trimmer that will do sheetmetal?

Has anyone tried this, or have a better suggestion than cutting it by hand? Does anyone think a carbide bit for woodworking would work?

Thank you all

Mike

.046 X 4.5 cutting disk in 4.5 inch side grinder. Very thin and cuts a straight line. Any place that sells hardware has them.

For sure wear a face shield. The really thin disks are easy to break.

I also recommend an Angle Grider for doing this ..... I buy 1mm ( .040 ) disc's made by Diablo in bulk, H.D. also sells them .... I think this is the Thinnest disc made

If you're going to be cutting lots of sheet metal, & you need to be able to cut around odd shapes as well as straight lines, you don't hafta rely on just disc cutters &/or angle grinders loaded with cutting discs, you can also get 'sheet metal nibblers' & 'sheet metal shears' - the nibblers do what they say, & chew/nibble a small section of metal out with each stroke, doing some hundreds or more strokes per minute; while the shears are heavier powered versions of what used to be called 'tin snips'.

Here's a nibbler that I chose at random from the first search I did on them: https://www.bing.com/shop/productpag...ue&FORM=SHOPIC

And a shear that I found easily the same way on amazon: https://www.amazon.com/DEWALT-DW890-..._t2_B011HX36GS

They're not the nibblers or shears I own/use, but they're similar & I find them a lot quicker & more versatile than disc-based cutting, easier for cutting complex shapes, & safer all round too - but depending on the model/type of either that you get, you might lose a thin strip of metal with every cut.

Personally, I wouldn't recommend cutting too much metal with a carbide bit (or any bit for that matter) that was designed for woodworking either - I reckon there's a whole bunch of reasons that they've been 'designed for woodworking' rather than 'designed for cutting sheet metal'

Peter! That's the only way to go for ease, accuracy, and safety.

Ok ... thanks all!
