Cutting steel with a circular saw

[Michael Kellough]

Has anyone tried this blade with an ATF/TS 55 saw?

That is a 20mm arbor if the pic is too small.
Panasonic cordless circular saws have a 20mm arbor.

Shane  posted a link to a video showing the TS 75 cutting stainless steel here.
I haven't read of anyone using the 55 saws to cut steel.

Does anyone know what speed the 75 was running in that video?
I know dedicated dry cut saws run at around 3200 rpm in the
7-1/4" diameter so I'm guessing the 75 ran slower.
Does anyone know the correlation between speed numbers on the saws
and actual rpm?

Okay, I did my homework.

The TS 55 has speed settings from 1 to 6 with an rpm range of 2000 to 5200.
So...

1 = 2000
2 = 2640
3 = 3280
4 = 3920
5 = 4560
6 = 5200

The Panasonic saw that uses the 5-3/8" metal cutting blade runs at 3600 rpm
so the ATF/TS 55 saws should be set to around 3.5.

Thanks for doing the homework Michael, if you end up cutting some steel please report back on your experience.
