Diamond Pacific and other companies sell and or can locate, a 5 to
10 weight food grade mineral oil... It is still a petroleum product,
albeit a highly refined one and supposedly containing only a small
amount of chemicals and their odorous fumes
Trim sawing, with blades up to 10 inches, should have little to NO
real problems in cutting, with 100% water alone as a lubricant...
Purchase a good blade which can be used in water MK 303, etc, there
are many good blades available for trim sawing in water alone.
Even with water alone cutting, it is very important to wear a mask
to protect not only your lung health, but your overall health as
well ! With oil trim sawing, wear an OSHA approved mask for oil
