Product Description
The Pepetools 90mm Flat Rolling Mill is a professional jewellery rolling mill designed for reducing metal sheet thickness, producing thin metal foil, and preparing flat metal stock for jewellery fabrication. Featuring precision-machined hardened steel rollers and a 4:1 reduction gearbox, it provides excellent leverage, control, and consistent rolling performance when working with gold, silver, copper, brass, and other suitable non-ferrous metals.
Unlike combination rolling mills that divide the rollers between flat surfaces and wire grooves, this model features a full 90 mm flat rolling area, providing maximum usable width for rolling sheet metal. This makes it particularly useful for jewellers and silversmiths working with wider sheets, metal strips, and larger jewellery components.
Built with a high-strength ductile frame and precision-machined carbon steel rollers, the mill is designed for durability and long-term workshop use. The outer 3 mm of the rollers are induction hardened to approximately 65 HRC, providing excellent resistance to wear and deformation. The polished, mirror-finished roller surfaces help produce smooth, consistent metal sheet with minimal surface marking.

Rolling Mill Operation & Care
For best results, reduce metal thickness gradually over multiple passes rather than attempting large reductions in a single pass. Anneal the metal as required between rolling stages to restore workability, prevent cracking, and reduce unnecessary strain on the rolling mill.
Keep the rollers clean and free from debris to protect their precision-polished surfaces. Avoid rolling hardened steel or other unsuitable materials that could damage the rollers. The rolling mill should be securely mounted to a sturdy workbench before operation.
Important Information
This is a flat rolling mill with a full 90 mm rolling surface. It does not include square wire grooves or half-round ring shank profiles. For customers requiring both sheet rolling and wire forming capabilities, the Pepetools 90mm Combination Rolling Mill may be a more suitable option.
The maximum roller opening of 5 mm represents the maximum separation between the rollers. The minimum achievable sheet thickness depends on the metal, its preparation, and the rolling technique used.
The Pepetools 90mm Flat Rolling Mill is an excellent choice for jewellers and silversmiths who require a durable, precision-engineered rolling mill with maximum flat rolling width, excellent leverage, and consistent performance for professional sheet metal fabrication.
