Key Features
- Three-in-one rollers: press gold, silver, copper, and other malleable metals into sheet, square wire, and half-round shapes.
- Sturdy and durable: 40Cr hardened rollers, cast iron hand crank, and painted sheet metal frame resist deformation during long-term use.
- Labor-saving design: 3:1 gearing; the pinion drives the large gear to reduce operating force.
- High stability: base screw holes allow secure mounting to a workbench for steadier operation.
- Low noise: double-sided gears help reduce noise for a quieter workspace.
- Adjustable thickness: T-handle precisely sets roller gap up to 0.36 in to fit different tasks.
- Protective packaging: custom foam resists compression and drops during transit.
Details
- Extra-long hand crank: cast iron body and durable grip provide smooth, even force.
- Gear cover: sheet metal side cover protects the gears during normal operation.
Application
- For jewelry making: converts gold, silver, copper, aluminum, and other malleable metals into thin sheets, square wires, and half-round profiles—ideal for jewelers and craftspeople.
Notes
- Screws are not included.
- Add lubricating oil to the connection ports at both roller ends once or twice daily during use.
- Remove the protective plastic film from the rollers before first use.
- Allow minor color differences due to lighting and a 1–3 cm measurement variance.
