McGraw 3" Air Cut Off Tool: Review and Testing - Harbor Freight

I do a test and review of the McGraw brand 3" air cut off tool that is found at Harbor Freight. I test this tool using a Dewalt cut off blade, high flow type V fittings, and on two different air compressors: 1) 20 Gallon Husky with 4.0 CFM @ 90 PSI and 2) 8 Gallon Kobalt with 4.0 CFM @ 90 PSI.
