asbestos fiber types
I need to cut a 4-5 ” hole in fiber cement shingle. any advice as to which brand and type of hole saw?
I have asbestos shingles and i need to vent a portable a/c so i’m going to replace a few shingles with fiber cement board so i can cut them. i heard these things are a nightmare to cut.
A jig saw with a metal cutting blade will work. First, trace the hole you wish to cut on the surface, then drill one hole big enough for the jig saw blade to fit through. Then simply cut out your pattern.
CAUTION! Don’t breath in the dust since asbestos is a carcinogen. Get a filter mask at any hardware store.
