The trouble with having a good strong bit is it's more likely to

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.


1/32 x 1/64 brass strip was furnished to fabricate the hardware, and you
have to drill a hole in the 1/32 side for the hinge pins. 1/32" is 0.8mm
so your 3mm isn't going to work. I bought a set of bits that ranged from
.030mm to 1.00mm.

Maybe some people get off on writing the lord's prayer on a pinhead, but
I'm not one of them. If I ever build another boat it wil lbe at least
12' long, not 6 inches, and I won't need 4x magnifiers to see the damn
thing.

To really top the cake Amazon labels it as 'Model Shipways 18th Century
Longboat 1/4" Scale Wood Model Kit - Intro to Shipmodeling'


I like a model boat to be about 2 foot long, although even that can be fiddly.
