These are the 64mm flat tempered-steel grinding discs Mazzer specifies as part number 189D — the same burrs your grinder shipped with, not a look-alike substitute.\u003c\/p\u003e\n\n\u003cp\u003eBurrs are a wear part. As the cutting edges dull, grind quality drifts before it fails outright: shots start channelling, the grind setting creeps finer to hit the same dose time, fines increase and the cup loses clarity and sweetness. A fresh set restores the grinder to the way it ground when it was new — usually a bigger improvement to the cup than anything else you can do for the money.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Mazzer part:\u003c\/strong\u003e OEM 189D discs, machined to Mazzer's own tolerances so they seat correctly and hold alignment in the burr carrier.
