Durston 1037 Molly C165 Rolling Mill With 50-1 Reduction Gear - 128.177

The Durston Molly C165 is a professional combination rolling mill featuring the brand's patent-pending 50:1 reduction gearbox—delivering exceptionally light turning effort and a wider rolling area than the Olivia model. Designed for studios that demand effortless operation and generous flat rolling capacity, the Molly C165 combines a front-mounted turning wheel, induction-hardened rolls, and a highly calibrated adjustment wheel into a solid single-cast body built for precision and durability.

Features

• 50:1 reduction gearbox (patent pending) – 50 handwheel turns equal 1 roll revolution for exceptionally light rolling effort
• Front-mounted turning wheel operates comfortably standing or sitting
• Induction-hardened rolls for long-lasting, consistent performance
• Highly calibrated adjustment wheel for precise, repeatable gap settings
• Combination mill – handles flat sheet metal and square wire in a single unit
• 110 mm flat rolling area on the main roll for wider sheet work
• 11 square wire grooves on the main roll
• Side extension with 4 half-round grooves (4, 3, 2, and 1.5 mm)
• Solid single-cast body construction for rigidity and stability
• Larger footprint than the Olivia model; does not fit the Durston Rolling Mill Stand

Specifications

What our Experts Think

• Maximum-Capacity Professional Rolling Mill

• Wide 165mm Working Width with Strong Flat Area
  Provides a 110mm flat rolling zone plus full combination capability, ideal for larger sheets, pattern work, and production-grade jewellery manufacturing.
• Full Combination Functionality
  Includes 11 square wire grooves and 4 half-round extension grooves (4mm–1.5mm), enabling sheet reduction, wire forming, and profile work in one machine.
• Built for Production Environments
  Heavy cast construction with induction-hardened rolls ensures long-term durability, stability, and consistent pressure under continuous use.
• Ergonomic Standing or Seated Operation
  Front wheel design allows comfortable use whether seated or standing, improving workflow flexibility in busy studios.
• High Output Efficiency Focus
  Designed for jewellers who need speed, reduced physical strain, and repeatable precision when working at scale.

  Best suited for professional workshops, manufacturing setups, and high-volume goldsmithing where throughput and consistency matter most.

Q&A

Maintenance Tips

• Clean rollers after every use – Wipe the 165mm flat and wire grooves immediately to remove filings and prevent scoring on the induction-hardened rolls (~64 HRC).
• Protect with light oil film – Apply a thin layer of rust-preventive oil (e.g., 3-in-1) when idle; always fully clean before rolling to avoid contaminating metal stock.
• Maintain the 50:1 gearbox – The ultra-high reduction system is low-effort but still requires periodic light lithium grease to keep torque transfer smooth and prevent long-term wear.
• Keep grooves and extensions clean – Regularly remove debris from 11 wire grooves and side extension channels to ensure accurate wire forming and prevent uneven pressure marks.
• Avoid overloading thickness – Do not exceed ~6mm sheet capacity; always reduce in gradual passes instead of forcing heavy single reductions to protect rollers and gearing.
• Use only clean, annealed metal – Dirty or hardened stock increases wear on precision rollers and reduces surface finish quality.
• Check alignment regularly – Ensure even pressure across the full 165mm width to prevent tapering, uneven wear, and gearbox stress.
• Secure mounting is critical – Bolt firmly to a heavy, stable bench or dedicated stand; the large frame relies on rigidity for accurate rolling performance.
• Store in dry conditions – Prevent humidity exposure to protect rollers, bearings, and cast frame from corrosion.
• Never touch rollers with bare hands – Skin oils can cause long-term spotting on precision-ground steel surfaces.
