About
Coil Width Calculator calculates coil width for cutting round blanks (circles) from stainless-steel coil (or any sheet) using a staggered/hex layout.
How it works:
- Enter the circle diameter (inches or mm).
- Select the number of lines (1–10).
- The app applies industry rule-of-thumb multipliers with per-line offsets and shows the coil slit width in mm plus a rounded suggestion.
Features:
- Unit toggle: inches ↔ mm
- 0.25″ scrolling wheel for quick size selection
- Quick Table for 1–10 lines
- Works offline; no sign-in
Made for:
Tool rooms, press-shops, coil slitters, and production planners who want a fast, consistent slit width reference on the floor.
Note:
Results are based on practical shop multipliers and offsets. Always verify against your die layout, material tolerances, and QA specs before production.
