Rancilio Rocky / MD40 / Obel Bregant 50 mm (suitable for Junior and Roma models only) espresso grinder burr set. Aftermarket burrs made to the same quality standards as OEM.
Ø 50x31x8mm left hand rotation
For Rocky users: the burr mounting screws reportedly get VERY tight and may strip when you try to remove them. You may want to consider purchasing an extra set of six
