Measured the milling end-mills etc with my vernier calipers. OK shank = either 6.3mm or 3.1mm. Just need to get 6mm and 3mm collets. WRONG. Collets arrived - tools don't fit. Measure again - yep 6.3mm and 3.1mm shanks. WAIT 1/4" is 6.35mm and 1/8" = 3.175mm. So all my endmills etc are imperial not metric. Note to self: need to be more precise in metalwork.

211 forum posts 18 photos	Hi Ed, Yes - I tried that and the tool goes into the collet but then the splayed collet doesn't go far enough up into the taper for the drawbar to connect with the collet. But never mind - I've ordered some Imperial collets - not expensive and widens my range of possible tools.
