110mm vs 130mm Combination Ultra Mill: Which Bench Size?

Category: Buying Guides
Compare the 110mm manual and 130mm electric Combination Ultra Mills by bench space, throughput, and budget so you pick the right flat-and-wire rolling mill.
Quick answer
Choose the 110mm Combination Ultra Mill with Ductile Frame if you work at a compact bench, roll mostly short runs, and want a manual mill with a 4:1 gear ratio. Choose the 130mm Combination Ultra Series Power Mill if you need electric throughput and can give up more bench space and budget.
Bench footprint and power needs decide more than roller width
The 110mm mill is a manual unit with a 4:1 reduction gearbox, so it mounts where you can turn a hand crank and clear the handle swing. The 130mm Power Mill is built on a machined aluminum base and runs from a direct-drive electric motor, so plan for a power connection and enough clearance around the machine rather than crank space.
If your bench is shared with a torch or a polishing motor, the manual 110mm mill is easier to move aside between tasks. The 130mm electric mill rewards a dedicated station where the cord and switch stay clear.
Throughput and control trade-offs
The 130mm Power Mill uses a 100:1 reduction gearbox and is adjustable up to 17 RPM, which suits repeated rolling and texturing with texture plates. The 110mm mill relies on its 4:1 gear ratio and hand feed, giving direct feedback on each pass but requiring more operator effort over long sessions.
Neither mill is the right answer for every shop: the manual 110mm keeps cost and complexity down, while the electric 130mm trades that simplicity for speed and consistency.
What the catalog does and does not tell you
The 110mm mill lists a 57mm flat area, a 5mm maximum opening, square wire sizes from 1.0 to 4.0, and ring shank half-round profiles. The 130mm Power Mill listing does not supply roller width, roller diameter, or maximum opening in the catalog facts provided, so do not assume those dimensions; confirm them with the product page or the manufacturer before buying if your work depends on a specific opening or wire size.
Decision rules for picking your bench size
- If bench space is tight: Pick the 110mm Combination Ultra Mill with Ductile Frame when you have a compact bench and can dedicate clear space for a hand crank rather than a power cord. Measure the handle swing before you commit.
- If you roll long or repeated runs: Pick the 130mm Combination Ultra Series Power Mill when electric feed and adjustable speed up to 17 RPM will save you fatigue across many passes. Confirm you have a nearby outlet and clearance for the machined aluminum base.
- If you need specific wire or ring shank profiles: Choose the 110mm mill when its listed square wire sizes (1.0, 2.0, 3.0, 4.0) and ring shank half-round profiles match your work; the 130mm catalog facts do not list those profiles. Verify the 130mm roll profiles with the product page if you need them.
- If budget is the deciding factor: The 110mm manual mill is the lower-cost entry point; the 130mm Power Mill costs more because of its electric drive and larger frame. Set a total budget that includes bench space and any electrical work.
