I have a jig for drilling 5mm holds at 32mm intervals to comply with the
European cabinet system.
Most drill bits are 3-4" in length. Why don't we have shorter bits for
this type of work? A shorter bit would seem more managable and would be
easier to control with a hand drill.
Question: Could a standard bit be cut and resharpened to accomplish this?
See part number 8255A39 @ http://www.mcmaster.com .

Try using depth stops on the bit itself, they are available in most common
sizes & generally tighten on with one or two flush allen key head screws. I
have a set of 8 that I think came from Vermont American (not 100% sure).

Maybe im missing something - but why not just break off the other end of the
bit?
I have snapped a few bits before - and just rechucked them - just need to
make sure the jaws dont grab in the flutes.

Drill bits are available in a variety of lengths and what you're looking for
is called a stub drill which is about 1 inch shorter than a standard bit.
Probably not available from the Borg (never been there I'm in the UK) but
any decent supplier should be able to help. The problem with shortening a
standard bit is that the flutes get shallower as you move towards the shank
which may cause problems with chip clearance. Hope this help

Shorter bits are readily available but you won't find them at he borg. Go to
anyplace that supplies machine shops and buy screw machine length bits.

Yes they can, any machine shop can handle the task for you. a surface
grinder with a whirly gig can shorten the bit and put you cutting edge back
on.
You could do this yourself with a die grinder to cut it off,clean up the
burr, and a neat little tool called a "Drill Doctor" to resharpen the bit.

Cut off the other end. May need to do this by grinding.

The web of a twist drill bit gets thicker further away from the point. See
my other post on this subject for a far better and more cost effective
solution.

Hi -
Don't forget that some of that bit length is used to carry chips up through
fixtures or guide bushings...
There are drills designed for single purpose uses such as you describe, they
just generally have no appeal for consumers...
Cheers -
Rob
Just a thought. Why not cut a little off the end that goes into the
drill? Surely seems simpler than recutting the tip.

Excellent suggestion. Why couldn't I think of that?
I agree that in some cases shorter bits might have advantages, and when this
occurs you can "cut, break, or whatever" a bit to meet those requirements
and resharpen it. However after you do this you have a short life bit that
may not be able to be resharpened. I prefer to use the depth stop on my
drill press and keep my bits long as long as I can.
