How To Drill HSS?

George Van in WI
>Is it possible to drill HSS? I have some 1/8" thick that I would like to make into bits for a hollowing tool. The bit I tried did not penetrate. Maybe I need a different angle on the bit or a method to heat the spot. On thinner metal scrapers I was able to spin a nail head creating a hot friction spot to loose the temper and drill without loosing the overall temper of the piece.
