Serious jewelers and metalsmiths - meet your new best friend. This professional 90mm rolling mill flattens metal like butter with its mirror-finished, induction-hardened rollers (65Hrc hardness!). The 4:1 gear reduction makes rolling effortless, while the solid steel construction handles years of studio abuse. Adjusts from 0-5mm thickness for perfect sheet metal or wire every time. Made in Oklahoma with aircraft-grade aluminum gears because "good enough" isn't in our vocabulary. Pro tip: The "T" bar adjustment keeps rollers perfectly parallel for uniform thickness. Warning: May cause excessive jewelry-making marathons.
