Brownells stuff is usually real quality. You should be set with that kit.
I have a Pachmayr set, a small Chapman set, and some diamond grit tipped ones that my brother
got me for Christmas a couple of years ago. I save them for special use on tight "stuck" screws,
since I expect the diamond grit to have a limited lifetime. It really works, high friction, keeps the
tip from wanting to cam out under torque. Since they will wear out, only use them when needed,
for their special ability.
I also have several holders for standard 'buy them in a tin' Phillips tips, used for sheetrock and
deck screws. They work well for any phillips, which are rare on guns except some buttplates.
The replacement hardware store hard straight bit tips are pretty good, but not so easy to find
as the phillips.
