Homebrew PCBs

Just checked my Harbor Freight flyer from yesterday's mail
they have a knock off "Dremel" type rotery tool on sale 
($20.00 USD) until Jan. 30, 2006

I have not seen the tool in person, I'm just posting the
information for anyone who may be interested, so if it turns
out to be a piece of garbage, don't blame me.

Thanks for the tip!

I was looking for a cheap quiet one around Christmas, but have been 
stuck finishing up a bunch of side jobs people have assigned me, and 
haven't yet grabbed anything. All I can find here are the usual 
Dremels, B&D's, and GMC's. Twenty bucks isn't much of a risk.

We've got a Harbor here too, but I've only been once. They just told 
me they've got that offer in store too. What's the deal with that 
Chicago Electric brand? The HF site turned up like fifty pages of 
results for a search on it. They had everything from tile saws to 
extension cords. They've also got a 12v roto in a kit for under $15 
(with an AC/DC transformer). I don't know what that sounds like, but 
the cordless brand name ones were supposed to be exceptionally quiet 
from what I read.

-Take Care

MIGHT (???) be able to use one of these Keyless Chucks

I have one of these that I use with my real Dremel, I can use 1/8 shank
"PC Board" bits (i.e. drillbitcity.com ) or smaller / larger strait 
shank bits without having to change a collet. I don't know if these 
chucks would fit the Harbor Freight "knock off" or not, as I said
before, I have not seen that tool in person.

I just need the "PC board sized" bits with 1/8" shanks. Where can I
buy new ones besides these reconditioned ones?

Don, I coincidentally saw a multi-pack of those on the HF site while I 
was looking (maybe a 50pc). It was under $10. They looked like the 
refurbs I just bought, which all have eighth inch shanks.

I still can't get over that brand and some of the prices on the larger 
power tools at that site. There's an angle grinder in there for $9.95. 
At those prices, worst case scenario, some of that crap could be good 
for a laugh after it breaks (maybe not immediately afterward).

I'm still wondering if anyone's used a cordless or 12V type roto for 
PCB. I'm not sure they'll have them connected for listening. FWIW, my 
etched holes and pads are usually enough to keep down any significant 
side to side bit play, and I've got a larger press and several power 
drills for bigger holes, so a cheap chuck or a tad less power may not 
kill me.

             -Thanks!
George

PS Don- Just an uneducated guess, but it may be possible that the 
resharpened stuff isn't all that much different than new. It sounded 
like they're constantly being popped out of high quantity drilling 
machines as they dull, and going right back to whomever shaped the 
edge to begin with (could be wrong though). I hate to admit it, but 
I've gotten lazy and cut with a broken one before. At the PCB speeds, 
I almost couldn't tell the difference.

Check my post 11737.   Those bits have 1/8" shanks.

Others have recommend carbide bits, as steel dulls rather quickly.
These reconditioning places don't have carbide ones do they?

Yeah (mine are at least). They came from "Tools and Tunes"(good place) 
from a tip here in the group -

I use a Dremel MiniMite 4.8V rechargable tool (Model 750) to drill  the 
holes in the boards I make. It has 2 speeds, I put it on high, and with 
the extremely cheap bits that I got at harbor freight, I have not broken 
a bit in it, and it is like a hot knife in butter, although I have 
broken several of the tiniest bits without even trying  when they 
weren't in the tool. The bits I found were in 2 small plastic boxes and 
appear to be made to fit in a standard dremel tool, without buying any 
extra parts. I usually can get a couple hundred holes between charges.
