Bending Sheet Metal vs BendSource

The calculator counts the the total flat length according to the K-factor you specify. If you do not know the value of K-factor, then the program, determining the the total flat length, depending on the method of bending and stiffness of the material offers approximate values of the K-factor. The program helps to easily calculate the real value of K-factor for your material, tool, tooling, technology.

BendSource turns supported EMT layouts into tape-ready fractional marks while keeping the formula, bender value, rounding rule, and source visible. CALCULATE SUPPORTED EMT BENDS • Offset bends with spacing and shrink • 90° stub-ups and back-to-back 90s • 3-point saddles using sourced 45° and 60° center-angle methods TAPE-READY MARK SHEETS See numbered M1–Mn positions, bend references, spacing, and rounded inch fractions in one place. Choose the rounding increment used for the displayed marks. CHECK THE METHOD Open Formula Mode to review the substituted values, unrounded result, preset provenance, manufacturer document, cited pages, and applicability notes. USE YOUR BENDER VALUE For supported 90° methods, you can save a take-up value read from your own bender or manual. User-entered values remain clearly labeled Check Bender and are never presented as manufacturer presets. PRIVATE AND OFFLINE Core calculations, saved Mark Sheets, and user presets stay on your device. BendSource has no account, ads, analytics SDK, or subscription. SCOPE Version 1 supports 1/2-inch, 3/4-inch, and 1-inch EMT for the bend methods shown in the app. A calculated result confirms the math and selected inputs; it does not claim a physical bend, jobsite conditions, or a specific bender has been field verified. Offset calculations and the source catalog are free. One Lifetime Unlock enables the other supported calculators, saved Mark Sheets, and user presets.
