The only non-replacement burr option that I'm aware of is the burr exchange program that Ditting runs... though iirc the savings is not significant.

 

So the answer is no... just gotta buy replacement burrs.

Hi Michael,

 

When you look at the burrs from the side you see a set of triangular waves with the edge of the wave slightly overhanging the trough of the next wave.  All those "waves" or teeth are cut individually on a machine tool.  The individual burr must be mounted in the machine by hand.  The angles of the teeth are very precise, maybe to a 100th of a degree.  I'm sure you could find an old school machinist to essentially reverse engineer the burrs for you and then take two solid days re-cutting them.  And you would end up paying over a $1000 for his time.  Even though the burrs look simple they are actually complex to manufacture, hence the price.  And because the complexity comes from how the teeth achieve their specific geometries sharpening existing burrs really isn't any less complex, or expensive, than forging new ones.  Which is why you don't get a price brake from Ditting when you send in old ones for resharpening.

 

You are SOL.

If you establish a wholesale account with Bunn (if you are a roaster/wholesaler) you should be able to get the burrs for around $100 plus shipping. If you are not a roaster ask your roaster to help you get burrs for your grinder at their cost.

Thanks again for the advice...I replaced the burrs and the coffee tastes like $200 better already!
