Combination waltz DRM 130 Durston

Durston DRM C130RE Combination Roller with 5:1 Gearbox and Side Extensions

The DRM C130RE from Durston Tools is a hand-operated combination roller from the proven DRM series for sheet metal, square wire, and half-round wire. The model designation describes the features: “C130” stands for combination rollers with a 130 mm roller width, “R” for the reduction gear, and “E” for the side roller extensions.

The precision-hardened main rollers, with a diameter of 60 mm, offer a flat rolling area of 75 mm for sheet metal and pattern rolling, as well as 11 square wire grooves ranging from 8 mm to 1 mm. Sheet metal can be rolled up to a thickness of 6 mm, and wire up to 8 mm.

The side roller extensions come standard with 4 half-round profiles and expand the range of applications, such as for the production of ring rails. Additional extension rollers with different profiles are available as options.

The self-lubricating 5:1 reduction gear significantly reduces the effort required for rolling. The roller gap is adjusted via a calibrated handwheel on the top. As with all rollers in the DRM series, the frame is made of solid cast iron, and the rollers are induction-hardened to 64 HRC. This ensures high stability and a long service life in professional workshop use.

For safe operation, the roller should be securely mounted on a suitable roller stand or a sturdy workbench. For larger cross-sectional reductions, it is recommended to anneal the material between individual rolling passes.
