In this grinding roll holder an excellently optimized version was actually created with the previous model! Unlike Altvorsatzgerät also a tool-free exchange of the grinding roller can now be done, and this goes even considerably faster by equip. Admittedly, the new is also a land more expensive - but if you often have to change the role because of the grain size (which then a right fumbling is), put you in the past, often several grinding roll holder on which had mounted the various grain sizes.. This is now superfluous, since a grinding roll change is "Rip-Rip" done! Had almost dreamlike when Dremel would also bring out the small, thinner grinding roll holder in this way - although I'm not sure if it (due to the significantly smaller diameter) is technically feasible at all? This small "helper" is worth MEDIE full number of stars and my strong buy recommendation for those who like "dremeln" !!!
