to start with, in my opinion, using a carbide tipped blade on the common chop saw is not a safe practice in any way. those saws spin way too fast.
what i was wondering about, is there a saw out there that is specifically designed to use a carbide tipped blade ?
i have seen some slow rpm saws used to cut metal, but i can't remember where. i was wondering if anyone had any experience with one.
band saws work great, but take up more room.
i have discovered, however, the common chop saw [no matter the diameter] works best with cutting discs between .045 and .062 thicknesses.
