Aside from danger factor with this tool - as you can get hurt , One might still be best off with tools that are slower and safer , ANYWAY I completely burned it out in 45 min or so Blades still sharp just the same . It's going back to sears.
I would only use this tool for cuts that require a savings of time Like the brackets of a AC motor if your not in the mood to use screwdriver it does cut the ends of AL / copper / or brass radiators fast
