Product Description
The Pepetools Ultra 160mm Flat Rolling Mill is the largest model in the Pepetools Ultra Series, designed for professional jewellery making, silversmithing, and demanding metal fabrication applications. Featuring a full 160 mm flat rolling surface, this heavy-duty rolling mill is ideal for reducing precious metal sheet thickness, producing thin metal stock, and preparing wider sheets for jewellery manufacturing.
Equipped with a powerful 4:1 high-torque reduction gearbox, the Ultra Mill provides excellent mechanical leverage, allowing jewellers to roll gold, silver, copper, brass, and other suitable non-ferrous metals with greater control and less physical effort. Its large rolling capacity makes it particularly useful for workshops producing their own sheet metal for rings, bracelets, bangles, pendants, and larger silversmithing projects.
Manufactured in the USA, the Ultra 160mm features a high-strength ductile iron frame designed to provide superior toughness and durability compared with traditional grey cast iron housings. The precision-engineered spur gear system helps deliver smooth, consistent rolling performance, while the substantial 30 kg construction provides a stable platform for demanding workshop applications.

Why Choose a Flat Rolling Mill?
Unlike combination rolling mills that divide the roller surface between flat sections and wire-forming grooves, this model provides the entire 160 mm width for flat sheet rolling. This allows jewellers to work with significantly wider metal sheets without the limitations of a smaller flat rolling area.
The full-width roller design is particularly beneficial for silversmithing, producing larger jewellery components, and preparing sheet metal for stamping, forming, texturing, and fabrication.
Why Ductile Iron?
Pepetools uses high-strength ductile iron rather than conventional grey cast iron for its Ultra rolling mill frames. Ductile iron provides excellent mechanical strength, toughness, and resistance to cracking, making it particularly suitable for larger rolling mills subjected to substantial forming forces.
The rigid frame helps maintain roller alignment and consistent pressure during rolling, contributing to accurate and repeatable results. Its robust construction is especially beneficial for professional workshops where the rolling mill is used regularly.
Applications
- Rolling sterling silver, gold, copper, brass, and other suitable jewellery metals
- Reducing metal sheet and strip thickness
- Producing custom sheet metal for jewellery fabrication
- Rolling wider metal sheets up to 160 mm
- Preparing sheet metal for rings, pendants, earrings, bracelets, and bangles
- Producing wider sheet stock for larger jewellery and silversmithing projects
- Preparing metal for stamping, forming, texturing, and fabrication
- Professional jewellery manufacturing, silversmithing, and metalworking
- Jewellery schools, training workshops, and production environments
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, minimise cracking, and reduce unnecessary strain on the rolling mill.
Keep the rollers clean and free from debris to protect their working surfaces. Avoid rolling hardened steel or other unsuitable materials that could damage the rollers. Due to the size and weight of this machine, the rolling mill should be securely mounted to a sturdy workbench before operation.
Important Information
This is a flat rolling mill featuring a full 160 mm rolling surface. It does not include square wire grooves or half-round ring shank profiles. For jewellers requiring both sheet rolling and wire forming capabilities, the Pepetools Ultra 160mm Combination Rolling Mill may be a more suitable option.
The maximum roller opening of 7 mm represents the maximum separation between the rollers and does not mean that every metal or thickness can be reduced in a single pass. Rolling capacity depends on the material, its hardness, preparation, and the reduction attempted per pass.
The Pepetools Ultra 160mm Flat Rolling Mill is an excellent choice for professional jewellers and silversmiths requiring a large, powerful, and durable rolling mill with maximum flat rolling width and reliable performance for demanding sheet metal fabrication.
