You are getting HSS drill
bits (the ones from Microscrews are HSS) or you are going to try drill
ing HSS? HSS is generally rock hard and them tempered.
I will verify that the drill
s I bought from Microscrews work on Allen screws, I think I have already done that but will check.
If the screws are stainless, then it is likely that the screws work harden while drill
ing making the task challenging. Stainless can be a major pita to work.
