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

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.
