Extra-long die grinder?

[MGregoir]

I am trying to find a 12" working length (not overall length, the length from the base of the grinder to the collet) pneumatic die grinder.

Ingersoll-Rand and Chicago Pneumatic top out at 6", and Dynabrade goes to 7-1/4". Does anyone have any ideas?

can you use a 6" burr with a 6" die grinder?
