Jeg's Reversible Extended Reach Cutoff Tool

Just a thought, but it might not be the tool that is the problem.

If you don't have a large compressor that puts out the CFM required for the tool that will make it work like crap as well.
Pretty sure the compressor isn’t the issue. 5hp, 60 gallon, two-stage with careful attention paid to pipe, hose, coupling sizes in order to minimize restrictions.
