Invest in a box of Dormer jobber drills and you’ll never look back. Get the black ones if you use a battery drill, not the A002 ones. Those ones are fine in pillar drills etc, but the tips chip easily and the shanks are very soft.
Consulting the latest, (March '24) Orbital Fasteners catalogue,
page 268 lists both the A108 Dormer Jobber drill bits,
(one up from the standard A002),
and also the next level up, A777, 8% Cobalt drill bits, (especially good for stainless steel).
