Tools with the working left in.
The tools cover bend allowance, deduction, K-factor calibration, L-profile flat lengths and nominal sheet thickness. Each tool keeps its dimension convention, formula and assumptions close to the result.
Useful without an account.
The current tools calculate on your device. You can copy or print a result and optionally save a recent calculation in the same browser. No account or subscription is required.
Built around what can be checked.
Example inputs are labeled as examples. Source-backed tables retain their references. Tool limits are stated alongside the calculation. Mathematical checks do not establish production accuracy. Verify results against your material, tooling and a test bend.
