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.\u003c\/p\u003e\u003cp\u003eThe 150mm roller length and \u003cstrong\u003e5-to-1 reduction gearbox\u003c\/strong\u003e 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 \u003cstrong\u003eside extension rolls\u003c\/strong\u003e 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.\u003c\/p\u003e\u003cp\u003eSelf-lubricating, maintenance-free bearings keep the mill running smoothly over years of heavy use. \u003cstrong\u003eHardened helical drive gears\u003c\/strong\u003e 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.\u003c\/p\u003e\u003cp\u003eDurston rolling mills are widely recognized for holding their value better than virtually any other jewelry tool investment. \u003cem\u003eMade in Great Britain.\u003c\/em\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFirst rolling mill to offer full round wire rolls for true round wire output\u003c\/li\u003e\n\u003cli\u003e18 round wire grooves from 1 mm to 10 mm cover the full range of common jewelry wire sizes\u003c\/li\u003e\n\u003cli\u003e5-to-1 reduction gearbox significantly reduces the effort required for large wire reductions\u003c\/li\u003e\n\u003cli\u003eSide extension rolls include four half-round profiles: 4 mm, 3 mm, 2 mm, and 1.5 mm\u003c\/li\u003e\n\u003cli\u003eSelf-lubricating, maintenance-free bearings for long-term reliability\u003c\/li\u003e\n\u003cli\u003eHardened helical drive gears with special tooth form for maximum drive efficiency\u003c\/li\u003e\n\u003cli\u003eCalibrated dials on both top wheels with pointer for precise gap measurement\u003c\/li\u003e\n\u003cli\u003eMade in Great Britain\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eRoll Size\u003c\/th\u003e\n\u003ctd\u003e150 mm × 60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRoller Type\u003c\/th\u003e\n\u003ctd\u003eFull Round\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRoller Length\u003c\/th\u003e\n\u003ctd\u003e150 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRoller Diameter\u003c\/th\u003e\n\u003ctd\u003e60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWire Grooves\u003c\/th\u003e\n\u003ctd\u003e18 round sizes, 1 mm – 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Wire Capacity\u003c\/th\u003e\n\u003ctd\u003e10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSheet Thickness Capacity\u003c\/th\u003e\n\u003ctd\u003e6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGear Ratio\u003c\/th\u003e\n\u003ctd\u003e5-to-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSide Extension Profiles\u003c\/th\u003e\n\u003ctd\u003eHalf-round: 4 mm, 3 mm, 2 mm, 1.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e17\" L × 8-3\/4\" W × 10-1\/2\" H (430 mm × 220 mm × 265 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet Weight\u003c\/th\u003e\n\u003ctd\u003e104 lbs.
