I how 20 year old rocky grinder. clean it every six months (take all the screws out and clean). What is the difference between 40 and 50 style burr grinders that I see being sold?

Best Answer: Hi,
The Rocky Rancilio does in fact use the 50mm set and so does the MD-40 grinder made by Rancilio. They are 50MM BURR SETS.

Hello. Does this Rancilio Rocky D50 Burr Set come with the 6 bolts to fasten the 2 rings back into the unit? My existing bolts are worn and may not be reusable. Thanks.

Best Answer: I'm sorry, unfortunately we are unable to get the screws for the burrs, so the burr set we carry does not come with them. Although it's possible to strip them out, this is a rare occurrence. If it happens, you can probably find replacements from your local hardware store, just bring them with you to match them up!

Great seller. Great product.Review by Arthur K.
I initially ordered this set from Amazon, but was surprised to find only 1 (one) burr included for the same price. I had to request a refund and went shopping elsewhere. The item ordered from SCG was indeed a full set that is needed to replace dulling burrs. I had switched to using my Rocky only for pour over coffee as the burrs had worn down too much to make a fine enough grind for espresso. With the burrs replaced, ol' Silvia is back in action. The package itself was shipped in a timely manner, and I can recommend buying from this site. (Posted on 2/25/2015)
