Durston 1038 Molly F165 Combo Rolling Mill With 50-1 Reduction Gear - 128.178

Durston 1038 Molly F165 Combo Rolling Mill With 50-1 Reduction Gear - 128.178

The Durston Molly F165 Combo Rolling Mill combines the power of a patent-pending 50:1 reduction gearbox with exclusively flat 165 mm rolling surface, delivering effortless control over heavy stock. The front-mounted turning wheel makes this mill equally comfortable to operate standing or sitting, while the ultra-high gear reduction means 50 handwheel turns produce just one roll revolution — dramatically reducing the effort required for each pass. Built on a solid single cast body with induction-hardened rolls and Durston's highly calibrated adjustment wheel, the Molly F165 is engineered for precision, repeatability, and long-term durability in a professional studio.

Features

• 50:1 reduction gearbox (patent pending) – 50 handwheel turns equal 1 roll revolution for smooth, low-effort feeding
• Front-mounted turning wheel designed for comfortable use standing or sitting
• Exclusively flat rolls across the full 165 mm working width
• Side extension with 4 half-round grooves (4, 3, 2, and 1.5 mm)
• Sheet thickness capacity up to 6 mm
• Single cast body construction with induction-hardened rolls
• Highly calibrated adjustment wheel for accurate, repeatable gap settings
• Larger footprint than the Olivia model — not compatible with the Durston Rolling Mill Stand

Specifications

What our Experts Think

• Ultra-High Torque 50:1 Gearbox Advantage
  The Molly F165 delivers one of the highest reduction ratios in its class, making heavy rolling work dramatically easier while maintaining precise control over pressure and thickness.
• Wide 165mm Combination Rolling Capacity
  Built with a large 165mm flat rolling surface plus side extensions, allowing efficient handling of wider sheet metal and consistent profile work in fewer passes.
• Full Combo Functionality for Sheet + Wire
  Includes square and half-round grooves, enabling both sheet reduction and wire shaping from a single machine—ideal for multi-process jewellery production.
• Professional-Grade Durston Construction
  Solid cast body with induction-hardened rolls ensures long-term stability, high wear resistance, and consistent rolling accuracy under daily workshop use.
• Effortless Operation for Extended Work Sessions
  The 50:1 gearbox significantly reduces physical strain, making it suitable for long production runs or users who prioritize smoother, low-effort rolling.
• Flexible Standing or Seated Use
  Front wheel design allows comfortable operation from multiple positions, improving ergonomics in busy studio environments.
• Production-Focused Workflow Tool
  Best suited for professional goldsmiths and manufacturing workshops that require high output, wide rolling capacity, and minimal operator fatigue.

Q&A

Q: What is the Durston 1038 Molly F165 Combo Rolling Mill With 50:1 Reduction Gear (128.178)?
A: It is a professional combination rolling mill designed for jewelry making, used for sheet reduction and wire forming with a wide 165mm rolling capacity.

Q: What is it used for?
A: It is used to reduce metal thickness, roll wire, and prepare consistent metal stock for jewelry fabrication.

Q: What materials can it handle?
A: It works with gold, silver, copper, brass, and other non-ferrous metals.

Q: What makes this model different?
A: It features a 50:1 reduction gearbox, which greatly reduces the force needed to operate the mill, even with thicker or wider metal.

Q: Is it manual or powered?
A: It is a manual rolling mill with gearbox assistance.

Q: What is the main benefit of this rolling mill?
A: It combines a wide working capacity with very low operating effort, making it suitable for professional high-output jewelry production.

Maintenance Tips

• Clean rollers after every use – Wipe the 165mm flat + wire groove area immediately to prevent filings from scoring the induction-hardened steel surface
• Protect with light rust oil when idle – Apply a thin film of 3-in-1 or equivalent; fully clean before rolling to avoid contaminating sheet metal
• Maintain 50:1 gearbox regularly – Light lithium grease keeps the ultra-high reduction system smooth and reduces wear under heavy torque loads
• Keep side extensions and grooves clear – Remove debris from 4 half-round grooves (4–1.5mm) to ensure accurate wire forming and clean profiles
• Avoid overloading capacity – Max sheet thickness ~6mm; reduce gradually in passes instead of forcing heavy compression
• Use only clean, annealed metal – Dirty or hardened stock increases roller wear and reduces surface finish quality
• Check alignment frequently – Ensures even pressure across the full 165mm width, preventing tapering and uneven rolling
• Secure mounting is essential – Bolt firmly to a rigid bench; the heavy 75kg cast frame depends on stability for precision output
• Store in dry environment – Prevents corrosion on rollers, gears, and cast housing components
• Never touch rollers with bare hands – Skin oils can mark precision-ground steel and affect long-term finish quality
