Attach drill bit to cordless screwdriver?

Jul 09, 2007 20 Replies

Can I get an attachment so my small cordless screwdriver (1/4 inch hexagonal socket) can hold a small drill bit (eg 2mm)?



Sometimes I want to drill a hole but don't really want to get out my large cordless drill.



Thanks Alex


(I know there are mini drill kits like a Dremel but I would rather use my cordless screwdriver.)


Sir might need some of these...

Normal way would be to use drill bits with a hex end. I noticed them in B&Q the other day.

No he doesn't. You can't fit a round shaft in a hex chuck.

Be careful of these, the bit is just glued into the hex portion so when it says "not for high torque applications" believe them. I have managed to "spin" the bits in the hex portions on two (admittedly cheepo) of these hex shanked bits.

Either get a small chuck with hex shaft:

a set of bits with hex shank.

Either of those will get the bit into the codless tool, but codless screwdrivers can have low rpm for drilling. One way to greatly speed drilling up is to regrind the bits to steep cutting angles.

a 2mm drill? Good luck. ;-)

Would buying a larger codpiece help improve your tool?

No one said he could You can use them in between your fingers and twist to make the hole. Alternatively putting them in a chuck will speed up the process.

Thank you too. This looks like what I am looking for.

Well done mate. It looks just right. Thank you.

No problem. :)

Also try a search for 'screwdriver chuck' on Ebay.

cheers, Pete.

I did exactly the same - and glued the drill bit back into the hex with polyurethane glue - still using it.

Yes, I liked it as well, the postage cost is off putting though!

Thing to note with these is you won't get a good fit with a plug in chuck - it will wobble to some extent. Which will be a PITA for accuracy

- especially with smaller drill sizes.
