I made this for my Proxxon 4 jaw as it just came with an Allen key Cheers Paul 1 Link to post Share on other sites More sharing options...
Quarryscapes Posted July 21, 2022 Share Posted July 21, 2022 There isn't a chuck key for the 4 jaw independent, it just uses the same Hex key as everything else. (The proper Emco one anyway) Link to post Share on other sites More sharing options...
Tim V Posted July 21, 2022 Share Posted July 21, 2022 My proper EMCO one has a square end - to match the 4-jaw chuck! Oh and to the OP, it is 4mm across the squares. Link to post Share on other sites More sharing options...
