Dremel bits for cutting panelized PCB?
2004-04-02 by ggindele
I wonder if anyone can recommend a dremel bit for cutting panelized
PCB. What's better, a routing bit or the cutting wheel?

I use a Stanley knife to score the board on both sides, then snap it and
clean it up with a file. Much quicker than cutting it and the results are
quite neat.

Hello,
I'd suggest the routing bit. The best type for pcb material looks
like it has elongated diamond shaped facets as cutting edges...

I use a shear. Very clean and fast. It makes a complete mess of
phenolic but FR4 is very clean. I dont use phenolic except in
emergencies so it doesn't matter.
I've used a dremel and agree on the routing bit but that makes a
nasty little mess.

carbide blade in tablesaw --> great.
edges like polished, and straight..
or a shear, but the handheld sheetmetal shear bends the board slightly....

Agreed, I use a floor mounted 30" sheet metal sheer. flat bed,
straight cut. definitely overkill but I have it for other things as
well.

Dremel = ++dust
I have used a paper shear, but its a bit of a strain. A metal shear is
just the ticket. You might be able to use one at a local sheetmetal
shop, hight-school, hospital shop, etc.

that the edges of the boards I cut yestarday are identicle to the
factory edge.
I need to cut odd shapes in boards and notches for things like
elongated holes for power connectors or reliefs for getting around
mounting holes or standoffs.
On some projects, you can use a Vee shaped tool and etch a grouve,
then snap the board on the grouve.

Dave,
This is for the bakelite (white) or phenolic(light to medium brown,
as sold by radio shack) boards, correct?
Because the epoxy based boards will make short work of destroying a
regular milling bit...

(anyone know a good source for bakelite at low prices?)
The routing bits I have been using are regrinds, the 50 for $15.00
variety and the edges are very good.
On the boards I cut yestarday, I did a final inspection to see if I
made any errors. I could not determine which were my cut edges and
which were factory edges. It just doens't get any better than that.
Of course the bits will wear out, but getting 15 bits in the box is
not too bad. Some are 50 mil. some 62 and some 90 something.

PCB Shear (was) Re: Dremel bits for cutting panelized PCB?
2004-04-03 by Robert George
I ran across a nice little 4" PCB shear a couple of months back, but
unfortunately I can't find the link.
Does anyone know of a small, inexpensive PCB shear? The Kepro is
gorgeous, but it's also $550.
Enco has this 6" plate shear on sale for $60, but it's Chinese, so
the quality of the tool is not likely to be good:
