Mahlkönig K30 Burr Set

Mahlkönig K30/E65 Series Steel Burr Set

This is the current OEM burr set for the Mahlkönig E65 and K30 lines, now packaged and numbered as 275123 (superseding the earlier 306715). If your grinder is losing consistency, running hotter than usual, or you're just chasing a fresher, brighter cup, worn burrs are the most common culprit and this is the direct fix.

INSTALLATION

Straightforward for anyone comfortable opening a grinder's burr chamber, but note the burrs correctly (S vs. D) before removal so reassembly orientation isn't guesswork.

PRO TIPS

• Reset your grind adjustment to a coarser starting point after installing new burrs and dial back in gradually, fresh, sharp edges bite more aggressively than worn ones and will over-grind if you start at your old setting.
• Don't mix a new burr with an old, worn mate, pairing one sharp and one dull burr causes uneven particle size and inconsistent extraction even though the grinder "looks" fine.
• See our grinder burr maintenance guide for the wear signs that tell you it's time to replace rather than just clean.
