And with pilot drills, I always buy the cheapest possible, because
simply by moving your hand slightly to one side by mistake, you can
snap any bit of any quality. I'd rather lose cheap ones.


A cheap twist drill dulls quickly so then you have to push harder
and then snap.

I like a quality HSS with cobalt twist drill, it stays sharp a lot
longer so it cuts easier and faster.

Fine for larger ones, but thin drills for pilots, you can break any
quality drill by simply being not too exact with the angle. Better to
waste cheap ones.


Breakage has not been a problem for me. I guess US people are more
skilled with a hand drill. ;-)

I'm talking about the thin 2-3mm pilots. A few degrees off the right
angle and they just snap.


I won't let you near my 0.35 mm drills then... A couple of winters ago
I decided to build a model boat and figured starting small was a good
idea. Sweet Jesus, everything was tiny. I've built real boats faster. At
least for me it was not a relaxing experience.

If it's plastic, fine, but drilling into hardwood with a 3mm pilot drill requires a steady hand, or several spare drill bits.

If using very small drill bits I insert as much of the shank as I can into the chuck. This lessens the chance of one snapping.

How does that make a difference? You need a certain amount out of the chuck to go into the workpiece.

Cheap drill bits for fine work are money wastedd

No, it means you lose less money when they inevitably fail.
