I saw an ad on ebay that claimed that the same collet that fits a 1617 Bosch also fits a bunch of DW and Hitachi routers. I gave my son a 1617 kit a while back and I just had a chance to compare the collet from his Bosch to the one for my M12V2 Hitachi which is the same as my VC also. They appear to be identical as far as cone diameter goes and either screws onto the other router. Therefore I'm convinced that the list I'm attaching is in fact correct which may be of help to some users of these models in finding replacement collets at some point. The ad is for a 1/4" but would apply to any Imperial or metric sized collet except the OEM part numbers would be different. The attached photo is a 1617 collet on the left and a M12V2 on the right. In the photo they appear ever so slightly different in cone diameter but in my hand I couldn't see any.
