" Keep the proper size tap drill bit in your drill case and you are all set."
I use the Klien tapping tool also. It's great for fixing the bottom hole in a metal box mounted in a masonary wall that usually has the screw rusted in. I use a #26 drill for the #10 tap, but I confess I don't know what the corrosponding drill sizes are for the #6 & the #8 taps, if anyone could help me out here.
