Coil Width Calculator

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.
