Re: [CAD_CAM_EDM_DRO] Taper ?

Hi RayHex,
I have lots of ER-16 collets. What I need are additional tool holders that
were made to fit the spindle of the Dyna Myte that's ground for ER-16.
Everything surrounding and ER-16 is spec DIN 6499 but, I have not found a
trace of what this is on the internet after searching 3 hours.
Apparently I would have to pay big bucks to some standards org for just
a peek.
Dyna Myte (Mechtronics) hasn't made this 2400 model CNC mill in 15 years.
Like you say, use one as a pattern.
Thanks, RichD
