Collet sizing; can you help? - UK Vintage Radio Repair and Restoration Discussion Forum

I've aquired an obsolete "Dremel-like" cordless mini-drill made by Ryobi (HTC 18). I'd like to buy a set of collets but can't find any information on the OD dimensions of current OEM types available (i.e. the OD of the long cylindrical section which is not slit). The Ryobi collet is about 4.2mm; could someone with a Dremel or similar measure one?

Many thanks

John

No Dremel, but my Black & Decker Wizard is around 4.3mm D.

Thanks John, sounds like there may be some generic standard.
