welcome back to the shop as most of you
know I do little hobbies where I cut
little rocks like this focus okay
focus there we go all right I'd cut
little rocks like this and used for
jewelry and some people want to know if
I can drill a little tiny hole in there
and so I ordered some of these some of
these old drill bits they were a dollar
maybe 50 cents apiece 10 bucks for the
whole set on Amazon and they are you can
zoom in there pretty much this diamond
coated crappy drill bits
I guess there's metal or they are metal
I think and it looks like they just dip
them in epoxy and and then dip them in
some diamond powder kind of like a sugar
cookie yeah we're gonna see how they
work for today's experiment what we need
is the rock the drill bit the brick to
put everything on and a bucket of water
for cooling set drill bit because you're
supposed to drill those under water and
then the the beer is for good luck most
people usually use these use a dremel
kit which is a little handheld guy it's
got a little variable speed on there
little tiny drill bit and they hand do
these but since I since I like precision
well this is a knockoff version the
procs on instead of a dremel since I'd
like precision we're gonna do a little
something different and we're going to
use
this guy big old drill press should be
fun all right I've got us all set up
here I've got a a I think that's a one
millimeter diamond encoded bit in there
got my rock sitting in there and got my
water and I've got the drill press set
to not go too far on the water because I
don't want my chuck to get all all full
of water coated in oil right now all
right we'll see how this goes oh and for
rpm sake I've got it set to 3,000 rpm
generally on the RPM side the heart of
the substance the slower you go but also
the smaller the drill bit the faster you
go so I honestly have no idea what to do
so I'm just gonna go fast
should work see how it works
okay there's too much water try again
okay take two less water contact
the drill bits bending I don't know if
you can see that
there's no bueno let's try that
something else all right take three I
tighten the out of it maybe that'll
work contact
still kind of bend a little bit too
happens
yeah let's not do that looks bad okay
next take I upgraded from the one
millimeter to the millimeter and a half
drill bit the chuck wasn't happy with
the one millimeter it's pretty on the
low end of what it can handle so maybe
this will work contact
[Applause]
[Applause]
yes all right let's see what it looks
like focus okay yeah look at that
there's a hole in that rock and I don't
think it really chipped at all that's
cool
I think what I'm going to do is I'm
going to move up a size and I'm gonna
countersink the outside of the back and
the front of the hole just so wet and
somebody you know put something through
it over time it won't chip any further
and for the next take I will put a
marker and Center it because that
is not Center at all all right all right
we are going to countersink those holes
make them a little bit cleaner and less
viable the chip in the future contact
I missed
you think this is in the finished piece
there we go nice
tsaldari let's do the back side back
sides gonna be little bit harder
all right just touched up see what it
looks like all right focus there a
little bit there we go zoom in over DS
in been already so not sure if you can
tell but that's counter sunk just a
touch chips off there nice good hole
minimal to Pidge and should last pretty
long time
all right thanks for watching
