The Victoria grinder mill for grain is built from high-quality iron. It features a grinding cover to keep your kitchen space clean, an adjustment screw to change the coarseness of your milling materials, durable cast-iron construction with double-tin plating to resist stains and corrosion, high-performance anti-erosion discs made of white iron for maximum durability and performance, and protective non slip rubber to prevent slipping and damage on your surfaces. The clamp adjusts to most tables and boards 1/2″–2″ thick for easy adaptability.
