Multi Cutter

[leevis]

Hi All
I need a to chop some fire stop and architrave at a really low level and the only way that I can see to do this is with a multi cutter (one of those plunge saw things).
The cheapest one I can find is around £43 but looking on the internet I see that one of the sheds sells a PTX Plunge Cutting blade which according to the blurb is compatible with most multi tools, now I have a Dremel and was wondering if these things fit them and how it would work as the Dremel end spins and these things kind of oscilate. Very strange but awesome if they are what I need because they are only £5

not sure why you think it will fit a dremel rotary tool
as you say one oscillates one rotates
the reference to " compatible with most multi tools" is because they have different fitments and use different blades
keep your eye on lidl and aldi as they often have them
