Key Features
48mm TriB-048-I Conical Burr
The innovative burr combines compression, shearing and piercing to break coffee beans more evenly before grinding. This helps provide smoother rotation, fewer fines and a more consistent particle distribution.
12-Point Burr Geometry
Alternating seating and piercing teeth guide the beans into the burr efficiently, reducing uncontrolled bean-to-bean collisions.
Ultra-Precise 15μm Adjustment
Each click adjusts the burr by approximately 0.015mm, offering precise control for dialing in different coffee brewing methods.
90 Clicks Per Rotation
The external adjustment ring delivers clear, distinct clicks and resists accidental changes during grinding.
Reduced Fines and Boulders
The TriB-048-I burr creates a tighter particle distribution and reduces coarse particles above 1,300μm for more balanced and even extraction.
High-Precision Bearing System
Custom bearings with approximately 5μm tolerance help maintain burr alignment and stability under load.
Large Ergonomic Crank Knob
The wider, fuller knob fits comfortably in the palm and provides better leverage for a smoother grinding experience.
Flared Bean Inlet
The outward-opening inlet guides coffee beans neatly into the grinding chamber and helps prevent spills.
Premium All-Metal Construction
Built with aluminium alloy and 304 stainless steel for durability, stability and a premium feel.
Easy to Clean and Maintain
The removable burr-lock structure provides convenient access to the grinding burr for routine cleaning.
