Fiber Cutter Power Estimator
See the fiber power range to evaluate for your material and thickness — a first-pass planning estimate to size a machine before you talk to sales.
This is a planning estimate, not a spec sheet. It uses the fiber power levels Boss Laser offers. Steel, stainless, aluminum, and brass are Boss data points; galvanized steel, copper, and titanium are early-planning estimates. Confirm final numbers against Boss cut charts for your exact machine.
How much power do you need?
Choose your material(s) and slide through the fiber power levels to see the thickest listed cut at each level.
Cut Thickness by Power
Steel, stainless steel, aluminum, and brass use Boss Laser data points. Galvanized steel, copper, and titanium are placeholder estimates until replaced with approved Boss Laser data. Pierce thickness always exceeds clean-edge production thickness.
