I've tried using a 7" cutting wheel on my circular saw. After about
24" they tear free from the
center mount. I went through 3 of them this morning and made 1.5 cuts.
The last time I cut up
a sheet I used a regular router bit. Needless to say the bit was dead
by the time I was done. I
also tried a 1/8" mill end I had gotten from somewhere locked in my
router. It did a really nice
job for about 12" then snapped. I'm thinking a beefier mill end would work.
