| Finding a chuck key! |

When faced with the same problem, I took the chuck into a tool shop and tried the keys they had. Second tool store I tried had the proper key. |

I had a similar problem and a collection of old chuck keys which didn't fit. I looked at the chuck and read the maker and model and looked it up on the internet. It probably helped that it was a Jacobs one - but that was also more incentive to get a key. Russell |

I guess if you measure the distance from the hole centre to (what would be) the pitch circle on the chuck, double it and multiply that by Pi, you'll get the circumference of the key at the pitch circle. Now see how many teeth are in that distance on the chuck and you'll have your tooth count for the key. |

Well some failure and some success/luck I turned down the pin on a couple of my multi keys and found that none of them fit the chuck. However, on a positive, the random key that came with the chuck but doesn`t fit, DID fit the new drill chuck that I said in my original post was on its way and had no key! It is just this chuck - I just wonder if it is slightly different being a tiny lathe chuck rather than drill chuck! Chris |

Chris Someone ought to tell you that 0 MT only means that you have two pieces of metal but one has a 0 morse taper shank that fits aan unknown drill chuck. All that anyone can guess that it is a little one. I'm sitting at my desk with a baby keyless Albrech which holds 0-to 1.5( I presume mm) Again, I am sitting with a Rohm 0.5- 4 PJO S1 and that it has a key called Vitrex 1. What the shanks should be and importantly what the female end of the drill chucks have to be determined - by fit. Maybe details as above might assist? Cheers Norman |
