If you end up buying the Pollard drill from Hugh, we have a spray etch machine at work (close to Hugh) that could be available for sale. Bought new, used about twice. If we need a PCB made I much prefer to use the CNC machine.I've had fun searching high and low and not had much success so thought why not ask here.
I'm on the hunt for a bench top manual drill for drilling circuit boards. My father has one that he sourced in the stated some 40 years ago and I need something similar (forget CNC that's on the cards but this requirement is still here).
The main requirements are
- Deep throat (needs to reach middle of A4 sheet)
- High speed (talking 20-30k minimum)
- Collet based (biggest drill is usually 1.3mm)
- Minimal throw (the drill pictured only requires me to push down about 10-20mm for the full depth, probably about a 1:1 ratio if not greater).
Oh and must be rigid - the speeds these drills need to spin at that's a must.
I'm not particularly interested in building or adapting one because simply it's time I don't have. All the stuff I can find for drilling PCBs is dremel based / more like a drill press and that's exactly what I don't want.
Budget - well it's critical piece of equipment so I'd say there isn't one. Whilst happy to pay a couple of k, more than that will make me question it and probably want a demo first.

Yes, CNC drilling and routing. Using a carbide vee engraving bit and a couple of passes the quality can be excellent. No tear out on fr4 board.Already have an etching bath that does what I'll need - free off this forum in fact.
Cnc as in drilling / routing? Not found them to be close enough to the accuracy we require for making circuit boards, always suffers from tear-out on the circuit board. Photo etching produces far better results we've found out.
I've yet to see a cnc router manage 0.25mm wide tracks spaced at 0.25mm something that is perfectly achievable with photo etching with minimal effort. I think 0.5mm pitch was just about the limit of a very expensive router when I worked at BAE and even then suffered on large boards because not being able to hold the FR4 flat.Yes, CNC drilling and routing.

Fair enough. That's beyond our usage.I've yet to see a cnc router manage 0.25mm wide tracks spaced at 0.25mm something that is perfectly achievable with photo etching with minimal effort.

For reference almost all my boards will have a 0.5mm pitch QFP on them or something similar.
Gryphon is the motor brand but I guess the seller doesn't realise that. Multico made good kit. I have a multico table saw.Multico Gryphon Drill | eBay

Has the deep throat but unfortunately not collets and does not look fixed by the column through the belt cover but it may be a brand to look into.
And no longer in business it seems from that link.Only 10k rpm
