Has anyone heard of or tried using Forstner bits for swich holes, etc in
chassis construction? I had read an article somewhere about using them on
aluminum chassis but didn't mention something like 20 ga. mild steel. I wonder
how it would work in either, especiall using bits with a TIN coating? I could
see how they wouldnt really need a starting hole, maybe just a spot from a
center dril to make a big hole like Trepanning. What I use now is either cone
bits, or chassis punches driven with an electric impact wrench. The larger cone
bits require a starter hole like 1/8" and of course the punches have to have a
hole to match the bolt. Any comments on these Forstner bits would be
appreciated.
Best,
Will
