What do I do when using wrong tool for cut and damaging duct?

Cutting, Holes, Penetrations & Field FabricationHigh-risk starter answer — foreman/GC/project verification required

Use the tool that makes a clean cut without crushing, tearing, burning, or warping the duct. Wrong tools turn a simple cut into repair work.

Field checklist

Confirm the material: galvanized, spiral, lined duct, stainless, painted/exposed, or rated/special material.
Choose snips, saw, grinder, shear, or other tool based on material and finish needs.
Protect nearby finished surfaces, insulation, and other trades.
Stop if the tool is damaging the piece.

Ask foreman

This tool is chewing up the duct. What tool do you want used for this material/cut?

Do not

Do not keep forcing the wrong tool because the cut is already started.

Why it matters

Basic cut quality affects safety, fit-up, sealing, insulation, finish work, and punchlist. Higher-risk/rated/structural cuts still require approval before cutting.
