31/64" Brad point bit?

[skipdiver]

I need a brad point bit slightly over 12mm but not as big as 1/2" (12.7mm) and the nearest i can get to that is 31/64", which is around 12.3 mm. Trouble is i can't find one. Plenty on American sites and i have found one that Fisch make for doing pen blanks but it is £22 and i don't want to pay that much for something that won't get a lot of use. Anyone know where to look to get a decent one that will cut cleanly into end grain of birch ply. I have a Fisch 12mm that cuts beautifully but it is just a tad too tight for what i need. I could cut with a 12mm and then just make the hole bigger with a normal jobber bit but would prefer to just do it in one hit with a brad point.

Use the £22 bit 10 times and its cost you 2.20 a time. at 22 times its a pound a go.
Work out your labour costs for buggering about drilling undersized and then expanding it 22 times.
You know it makes sense.

Or if you can get a jobbers bit then just re grind the end to create a usable brad point it's not that difficult with a bit of practice.

It looks a bit long to be honest, which is putting me off more than the price.

The re-grind is a good shout, never thought of that.

Colt make a 12.5mm and 31/64th 5 Star pen bits - M2. They're still long and around the £20 mark, though. Google will bring up some suppliers as will ebay.uk

Yeah, think a bit more searching is in order and i'm sure something will emerge. Just wondered if anyone could point me at a site to save me the bother. Thanks all for suggestions so far.

Here's a couple of 12.5mm bits

Seems that 31/64ths is the drill bit for pen blanks, which i didn't know, so will find something i'm sure. 12.7mm is way too slack, so i imagine 12.5 will be as well. 12mm is almost perfect but with it being a hole drilled very near the end on the edge of 18mm ply, sometimes the ply parts when i put the 12mm fitting into it, so i'll get a 31/64ths, which is about 12.3mm. Would prefer the clean cut of a brad point, so it looks like i'll have to shell out for one.

Thanks to all.

Might it be easier to change the size of whatever you're going to stick in the hole?

Just bought 200 of them, so no.
