What our Experts Think

• All-in-One Rolling Powerhouse
  The Double D4 features a stacked dual-roll design, combining flat rolling (top) and wire rolling (bottom) in one machine—ideal for maximizing productivity without switching tools.
• Wide 158mm Capacity for Larger Work
  With an extra-wide 158mm roller width, it easily handles standard 6” sheet metal, making it perfect for pattern rolling and larger-scale projects.
• Dual Gear System for Power & Speed
  Equipped with two interchangeable handles and triple gear reduction (up to 11:1), offering both high torque for heavy reductions and faster rolling for lighter tasks.
• Extremely Versatile Output Options
  Includes 19 wire grooves, multiple half-rounds, and side extensions, allowing you to produce sheet, square wire, and half-round profiles from a single machine.
• Built Like a True Workhorse
  Constructed from one-piece cast iron with induction-hardened rollers (~64 HRC), ensuring long-term rigidity, precision, and durability under heavy daily use.
• Efficient Workflow for Professionals
  The stacked configuration saves space while delivering multi-function capability, making it especially valuable for busy or compact workshops.
• Smooth, Low-Effort Operation
  Advanced gearing and bearing design provide controlled, low-resistance rolling, even when working with thicker metals or larger stock

Q&A

Maintenance Tips

• Clean after every use: Wipe both upper and lower rolls to remove debris and prevent surface damage.
• Lubricate key components: Regularly oil gears, bearings, and adjustment mechanisms for smooth operation.
• Roll gradually: Reduce metal thickness in stages to avoid stress on stacked rollers and maintain alignment.
• Monitor alignment: Check both roll sets for even pressure to ensure consistent results.
• Use annealed, clean metal: Prevent roller wear and marking by avoiding hardened or dirty materials.
• Protect all roll surfaces: Keep both rolling levels free from scratches and contaminants.
• Store in dry conditions: Apply anti-rust oil and keep away from moisture to extend machine life.
