Pietro ProBrewing 58 mm Vertical Flat Burr Kit, M-Modal

Made by Fiorenzato for their Pietro grinder line, this is the current M340 steel burr set, using a filter-focused "Pro Brewing" geometry designed to balance grind size and consistency for filter brewing. It's the direct successor to the earlier Dark-T burr kit.

SPECIFICATIONS

58 mm flat steel burrs, M340 steel, M-Modal / Pro Brewing geometry
Filter-brewing grind focus
Includes burrs and mounting screws

COMPATIBILITY

Fits: Fiorenzato Pietro grinders (both models, interchangeable)
Replaces: Fiorenzato #900002091/R; supersedes the earlier Dark-T kit (FZTPIETROPB-BURRKIT)

INSTALLATION

DIY-friendly for an experienced home user, see the How to Change Pietro Burrs video for the full process.

PRO TIPS

These M340 steel burrs are the filter-focused geometry, if you're mainly pulling espresso on your Pietro, this isn't the burr set to reach for; it's tuned for the coarser, more consistent grind that filter brewing wants, not espresso-fine precision.
