Eje interior Ottoflex (cable) 38-1/4 pulgadas

Found a Otto Frei OTTOFLEX Flex Shaft Rotary Tool Model BD on E-bay in "Like New" condition. Thought I would upgrade from a Dremel. I could tell from the pictures that the key end of the cable was broken off. Not knowing a lot about flex shaft rotary tools, I contacted this seller to inquire what hand pieces would fit this model. The sales rep assured me the Foredom handpieces would fit. Made the purchases of the Rotary tool and the Inner Flex Shaft on the same day. Perfect fit. So happy I was able to get things matched up.
