I have a small drill chuck – pre mounted on an MT2 taper – that unlike my other drill chucks wil take fairly small drill bits. It also seems to be a quality product. So it would normally be getting well used.

It is however missing the chuck key and search as I may at shows etc – I’ve never found one with the right tooth/hole combination.

Obviously ‘Jacobs’ drill chucks had different sized keys – but I’ve never seen their dimensions published. And did other manufacturers use Jacobs as a guide – or was it just suit themselves?

Any ideas!

Regards,

Any standardisation – and published tables?

Hi There

I think Jacobs went by numbers so a Jacobs chuck no 31 would have a K31 key.

Tried the Jacobs website?

http://www.jacobschuck.com/

Also I have seen multi fit 4 way keys available from various suppliers and DIY outlets.

Thank you for the feedback – the ‘Jacobs’ website has some useful info on their product range & I now have a PDF that lists their keyed chuck sizes with holding range. The key for each chuck is also listed as being “Kxx” but no dimensions are given – perhaps unsuprisingly.

Can anyone point me to the main dimensions of these keys – i.e. key ‘pitch’ & peg diameter?

Regards,

Ian T
