Can someone please tell me what type of drill bit I need to drill out a
5/16" diameter hole in my existing 2" mast with 3/8" wall. I want to go to
5/8 if possible but the mast may just be too hard.
I would rather stay away from the real expensive, like $150.00, drill bits,
instead preferring to use several say cobalt tipped or titanium tipped or
some kind of hardened steel bit.
I have looked at McMaster-Carr's catalog and see what they recommend in
print but was hoping someone would be able to give me guidance based on
experience.
The other hooker is I have to drill this on the top of a tower so staying
there for hours will not be pleasant, especially with a heavy half inch
drill.
This is a rather personal request on a Tower-Talk related subject so
personal replies might be in order to: w0yg@prolynx.com
Thanks and 73,
Charlie, W0YG..>>
