Homebrew PCBs

Just getting started on this toner transfer stuff---  My first board turned
out better than I expected-- I just used a copier at work on standard copy
paper, and a $22 Harbor Freight laminator!  I've tested all the traces and
not a single short or open! ( I made an "Eagle" conversion of an "Arduino
RBBB" by westfn :
http://www.instructables.com/id/Turn-your-EAGLE-schematic-into-a-PCB/)

So now to drill (cheap dremel-type).  Before I order carbide bits online I
was trying to find some locally.  I have read on here of people who have
found multi-packs of small carbide bits at Harbor Freight.  I looked through
our store and didn't find them (staff was busy and didn't have time to
ask).  Do the Harbor Freight stores no longer carry them?  (I didn't see
mention of them online either).

Any other suggestions, to be able to drill my board this weekend?

Thanks!
John C.

P.S. My $60 ebay HP p1102w just came today, so now I can try it on magazine
paper or transparency paper or press and peel or pulsar or homemade dextrin
paper or ....

Something like this product may be what you were looking for at Harbor
Freight: http://www.harborfreight.com/20-piece-solid-carbide-micro-bit-grab-bag-44924.html

In case the link doesn't come through it's item # 44924

You really do get what you pay for when it comes to micro drill bits.
There are some good places online but I've lost the links.  A lot of
jewelry supply websites sell them pretty cheap.

I find a Dremel drill and stand just breaks carbide PCB drills, you need something better. More the stand than the Dremel. DJ Delorie has a simple solution for using a Dremel If you use the Dremel then HSS drill bits are more robust and cheap enough. Move to Carbide later as the need arises.

Carbide PCB drills are available from McMaster Carr, but they are not exactly cheap. I found some at a surplus store, in the past cheap, but they are not in business anymore. If you have a PCB fab nearby you might be able to buy some used bits that they may just throw away.

Thanks Erik!  I searched for "drill bits" and of course that was not found
:)  I've seen the references here to places online, but I was wanting to get
my feet wet before I ordered more stuff...

I found the "micro-bit" at my local HF and am having good success so far,
thanks again!

Cheers,
John

I use resharpened drills from Mega Electronics (UK). They aren't cheap, 
but they work very well and last a long time if one is careful with them.

if you reside in canada, you can also get a nice set from princess auto for
cheap.

Drill Bit City has been a good online resource  for me over the years.

You will need a drill press to be able to use  carbide drill bits without 
breaking them every time. I use a $100 drill  press from Home Depot
that works fine even though it is not high  RPM.

One of the small Micro-Mark Drill Presses are nice to have for  around $200.

Cameron makes an excellent high-speed drill press if you  can
find one on Ebay for a good price.

This Micro-Mark Drill is very similar to the PROXXON that I own:

http://www.proxxon.com/eng/html/28128.php

It's made in Germany.

Where are the Micro-Mark made?

I find that the Dremel and dremel drill press stand acessory works wonderful and 
is probably the best setup short of a cnc machine.  If you look at my youtube 
channel you will se a video that I recently posted a video showing very closeup 
drilling a PCB.  I was using a #79 carbide drill in the video, thats about as 
small as I go but ocasionally I use a #80,  Most general PCB drilling I use a 
#60 carbide drill.  Please chekout the video and subscribe for future updates, I 
will be posting a new video this weekend.  Good Luck...

For those interested in youtube videos of my Homebrewed Printed Circuit Board
fabrication, PIC chip experiments, High powered LED projects, Arduino
applications, QRP kit builds, and Electronics Tourism, Please take at look and

As far as I know Micro-Mark is the North American variant
of Proxxon and goes by the name of Microlux. They are both
made by the same company.

Thanks, I never heard about the US “mark”.
