While cutting a sink opening in a counter top I hit an imbedded screw. Instead of the blade bending the gears broke. This never happened with either Milwaukee or Bosch jig saws, the blades would just bend. The Festool repair dept. said "it would cost 355.00 to repair the saw". I said "why should I pay 355.00 to repair a 350.00 saw?" He said "I abused the saw by hitting a screw". He said "I should have used a metal blade". That's when I knew I was talking to the wrong person. Has anyone had this happen to them? Maybe I shouldn't use Festool for construction. Should Festool tools just be by hobbyists.
