Mine did but I never use it as the supplier I got my collets from use M10 for MT2 and M12 for MT3. I just use M12 threaded rod with a nut on it. I've been meaning to make a self ejecting drawbar but haven't got round to it.

Self-ejecting drawbar? Do tell!

You can get a R8 to morse converter but not the outher way round http://www.arceurotrade.co.uk/Catalogue/Adaptors-Sleeves , I would go with R8 .

My chester 20v mill has one, when you undo the draw bar the top nut is held in a cup so it can't screw out the top, instead it pushes the rod down and ejects the taper.
Jonny:
Can get MT2 in 3/8"BSW, M10 and M12
MT3 in M10 and M12, may be more.
Just make up drawbars with desired thread if have several different tools. Spare MT3 mill unused had 3/8" BSW that came with it and made up two in M10 and M12 to suit the collets and tools had at the time. Easy enough to make.
Current mill is MT3 only have the M12 drawbar as all tooling is M12.

That's cool. My MT3 is always a pain. I know that they're designed for a drift but there's rarely room to extend the spindle, and you'd need to undo the drawbar all the way... ya, definite pain.
