Jarvis 303 Tapping head collet sizing
I recently bought a Jarvis 303 tapping head with a Jacobs chuck no. 440-J5. After looking in the current Enco catalog (page 310) at the collets in an effort to find the one that fits this chuck I am still in the dark. Can one of you wise men or ladies steer me in the right direction? They list a Jacobs tap chuck but do not reference a number. Steve |

Steve I have a Jacobs 440-J10 with two Rubberflex collets, I wonder if they're the same as for the J5. Not for sale, except with the chuck, and you already have one of those. Anyway if it helps, here are the specs on the two collets I have: No. J441--capacity, #10 to 1/2" No. J440--capacity, 5/16"-5/8" Each collet has six jaws, about 1/8" thick, set in rubber--5/8" long, and a 20 degree cone angle. Largest diameter across the points is 1 3/16".

From your description they seem like the right size. How does your chuck attach? This one is retained by a pin the way it appears although I have not taken it off the tapping head. How dear is the chuck and collets to you? Maybe we could work out a trade or cash if need be. Contact me off list at speterooooooooatoooooooowctaooooooodotooooooooonet take out the "o"s |
