Hi All
Not come across these angle grinder cutters that have been mentioned,
does anyone have a link to an image and seller of them?
I have to cut a large open a stainless steel pressure vessel (now
vented!) Its a dewar - like a giant vacuum flask for holding a couple
of hundred litres of liquid nitrogen. The two skins are about 4 or 5mm
thick and have some kind of insulation material between them - some form
of mica.
I need to cut through the outer skin to empty the mica and then through
the inner skin to prove that it is empty and very definitely vented!
I had planned to do this with a 9 inch angle grinder and a small stack
of cutting disks but am now wondering if these cutters in the small
grinder may be a better option - if only so that I can open up a smaller
hole in the inner skin.
Comments and group wisdom gentlemen?
regards
Dudley

Here's an example, though you should be able to find them for about
half the price, maybe from your local welding supplies house.
I find them invaluable.

I've got some bosch ones, 115mm from the local hardware shop. also 1mm
thick, and they cut quite nicely in mild steel and so on as well as SS.
