Anybody know of a collet supplier with id collets in the 1" long x 1/2 to 5/8 diameter range? i will need to grind a locationg dimater in the end andit will need to slide over another expanding collet to be actuated by. go to http://www.roviproducts.com/expandin.htm#mini to see what i mean. basically i am using a mite-e-bite id collet to drive the machinable mini collet. the smallest rovi offers is 1 5/8 long x 5/8 diameter. much too large for my app. if i can find a smaller version of the machinable mini collet i won't have to have them made from scratch. any help will be GREATLY appreciated. TIA!
