5 Best Grain Mills - Feb. 2022 - BestReviews

Other grain mills feature metal burrs. In most cases, the burrs are made from durable high-carbon stainless steel and provide more of a shearing action than the crushing action that stone burrs use. Metal burr grain mills are typically quieter than stone burr models, and there's no risk of the burrs chipping or flaking.

What is a Mill File? (with picture) - Info Bloom

A mill file can also vary in tooth configuration to suit different cutting applications. The tooth configuration is known as the cut of the file, which refers to how fine the teeth are. Cut sizes are identified by name, which from smoothest to roughest, include dead smooth, smooth, and second cut. Bastard, middle, and rough come after.
