Durston 1045 DRM-Round150RE Rolling Mill with Reduction Gear & Extension Rolls - 128.144

Durston is the first manufacturer to offer a rolling mill with full round wire rolls, making it possible to produce true round wire with few — or in many cases, no — passes through a draw plate. Traditional wire rolling mills form wire in a diamond or triangular profile, requiring additional draw plate work to achieve a round cross-section. The DRM-Round150RE changes that: its full half-round groove geometry produces genuinely round wire directly off the mill. A slight flash may occur at the seam between the two half-round shapes, and a single pass through a round draw plate will clean that up, but for many applications the wire comes off the mill ready to use.

The 150mm roller length and 5-to-1 reduction gearbox make significant wire size reductions far easier, reducing operator effort and delivering consistent, repeatable results. Eighteen round wire grooves ranging from 1 mm to 10 mm cover the most common jewelry wire sizes. The integrated side extension rolls provide four half-round shank profiles — 4 mm, 3 mm, 2 mm, and 1.5 mm — for rolling half-round shanks without a separate tool setup.

Self-lubricating, maintenance-free bearings keep the mill running smoothly over years of heavy use. Hardened helical drive gears with a special tooth form deliver maximum drive efficiency and long service life. Calibrated dials on both top wheels with pointer indicators allow precise, easy-to-read gap measurement for accurate, repeatable reductions.

Durston rolling mills are widely recognized for holding their value better than virtually any other jewelry tool investment. Made in Great Britain.

Q&A

Q: What is the Durston 1045 DRM Round 150RE Rolling Mill (128.144)?
A: It is a professional manual round combination rolling mill designed for jewelry making, used to produce round wire shapes, sheet reduction, and profile forming in one machine.

Q: What is it used for?
A: It is used to reduce metal thickness, shape wire into round profiles, and create consistent wire forms for goldsmithing, silversmithing, and jewelry production.

Q: What materials can it work with?
A: It is suitable for gold, silver, copper, brass, and other non-ferrous metals commonly used in jewelry fabrication.

Q: Is it manual or powered?
A: It is a manual rolling mill, but the gearbox reduces effort significantly for smoother operation.

Q: What is the main benefit of this model?
A: It allows jewellers to produce round wire directly through rolling (instead of only reducing wire), improving efficiency and reducing the need for drawplates in many workflows.

Q: What makes it different from standard rolling mills?
A: Unlike typical combination mills, it is specifically designed for round wire forming as a primary output, making it more specialized for wire production alongside sheet rolling.

Maintenance Tips

• Clean grooves after every use – Remove metal dust from all 18 round forming grooves (1–10mm) to prevent scoring, uneven wire shaping, and buildup inside precision channels.
• Light oil protection on idle – Apply a thin anti-rust oil layer on rollers and exposed steel when not in use; always wipe completely before rolling to avoid contaminating wire.
• Maintain gearbox (5:1 reduction) – The gearbox reduces effort significantly but still benefits from periodic light lithium grease to keep torque smooth and consistent under load.
• Prevent finning issues with proper technique – Rotate wire 90° between passes and adjust roll pressure slightly open/close to reduce side fins and improve roundness.
• Use only clean, annealed wire – Dirty or work-hardened metal increases groove wear and reduces accuracy of round forming.
• Check alignment regularly – Ensure even pressure across the full 150mm roller length to maintain consistent groove depth and avoid uneven deformation.
• Secure mounting is essential – Bolt firmly to a rigid bench or stand; cast iron frame depends on stability for precision rolling.
• Store in dry conditions – Protect rollers and bearings from humidity to prevent corrosion and maintain smooth operation.
• Avoid forcing heavy reductions – Do not exceed recommended wire capacity (~10mm) and reduce gradually to extend roller life.
• Never touch grooves with bare hands – Skin oils can cause long-term spotting on hardened steel and affect finish quality.
