I'm trying to make a base plate for an EVT Bicycle stand as cheap as possible.
I can get a 1/2" thick ASTM A36 steel plate with the 4 holes already drilled. My questions are:
Will I have any problem with a 3/4", 6FL, 90 Deg countersink into a 1/2" hole without a drill press?
If I can just use the bit with a power drill, can I get away with the HSS version ($30) or better off with the Cobalt ($40) or Cobalt with TiN ($53).
Only needs to sink 4 holes. Zero foreseeable use for this bit after this project. Don't want to get 3 holes done and have bit crap out.
Thank you for any advice!
