View Full Version : 5C collet ID specs

01-09-2010, 08:35 AM
Hi, im wondering if anyone knows the specs for making a 5c internal collet stop? I read online the hole is 24pitch and 1.041~1.047 depending on the manufacturer.. But im not exactly sure what the collet stop itself should be, as far as major diamiter and pitch diamiter (I have a nice set of pitch diamiter micrometers)

I need to create one thats 'standard' size as I need to check the ID threads for fit of all my new chinese collets, as Iv allready found 4 (out of 33) where something prevents the OD thread from functioning.
