🆕 Pepetools Ultra Rolling Mill (160mm Combination Rolling Mill)

Product Description The Pepetools Ultra 160mm Combination Rolling Mill is the largest model in the Pepetools Ultra Series, designed for professional jewellery making, silversmithing, and demanding metal fabrication applications. Combining flat sheet rolling, square wire reduction, and half-round ring shank forming in one heavy-duty machine, it offers exceptional versatility for jewellers working with gold, silver, copper, brass, and other suitable non-ferrous metals. Featuring an extra-wide 160 mm roller width, large 65 mm diameter rollers, and a powerful 4:1 reduction gearbox, this rolling mill provides excellent leverage, precision, and control when reducing metal thickness. The combination rollers include a 77 mm flat rolling area, nine square wire grooves, and five half-round wire profiles, making it particularly useful for workshops that regularly produce their own sheet, wire, and ring-making stock. Manufactured in the USA, the Ultra 160mm features a high-strength ductile iron frame designed to provide superior rigidity and durability compared with conventional grey cast iron housings. The large 65 mm diameter rollers provide an increased contact area for smooth, consistent rolling, while the precision gearbox and spur gear system help deliver efficient power transfer and controlled metal reduction.

Pepetools uses a high-strength ductile iron housing rather than the conventional grey cast iron commonly found in other rolling mills. Ductile iron offers 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 operation, while its vibration damping characteristics contribute to smoother rolling performance. This construction is especially beneficial in a large 160 mm mill intended for demanding professional workshop use. 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 Reducing and shaping square jewellery wire Creating half-round and domed ring shank stock Preparing metal for rings, pendants, earrings, bracelets, and bangles Producing custom wire and sheet dimensions for jewellery manufacturing Silversmithing, metal forming, and general jewellery fabrication Professional jewellery workshops, schools, 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 combination rolling mill featuring a 77 mm flat rolling area, nine square wire grooves, and five half-round wire profiles. The total roller width is 160 mm, but the full width is not available for flat sheet rolling. Customers primarily requiring wider sheet rolling without wire-forming grooves may prefer a dedicated flat rolling mill. 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 Combination Rolling Mill is an excellent choice for professional jewellers and silversmiths seeking a large, powerful, and versatile rolling mill capable of producing sheet, square wire, and half-round ring stock with precision and consistency.
