Magedori: Conduit Bending Calc

Stop hunting through preset lists for your bender.
Make one test bend and the app learns how your bender actually bends. From then on, the numbers match the pipe.

CALIBRATE TO YOUR OWN BENDER
Benders of the same size bend differently with make, age, wear and the hand on the handle. Book values drift. Bend a 90° on a scrap piece, measure it once, and the app works out your real centreline radius for that size and keeps it.

SEVEN BENDS
• 90° stubs and any-angle bends
• Kicked 90° (new in 1.2): marks for the 90° and the kick, distance between them, shrink along the run
• Offsets with distance between marks and shrink
• 3-point saddles
• 4-point saddles
• Single bends at any angle
• Parallel runs: how far to shift each mark

MARKS FROM THE PIPE END, IN ORDER
Results are a list of distances measured from the end of the pipe: ① bend start ② bend end ③ cut. Lay your tape along it and mark. Choose whether you measure to the back, the centre or the inside, and the red line in the drawing moves to show you.

TOLD WHY IT WON'T BEND, AND WHAT WILL
If two arcs would overlap, the app says so, says by how much, and offers an angle that works. One tap switches to it.

METRIC STEEL CONDUIT, IN MILLIMETRES
Heavy-gauge steel conduit to EN 61386 / BS 4568 from 16 to 50 mm, in millimetres. EMT, IMC and Rigid in inches and Japanese JIS conduit are included too.

BUILT FOR THE JOB SITE
• No sliders. Type numbers on the keypad or tap +/- steps
• Every feature works underground or with no signal
• What you enter never leaves your device. To improve the app, only anonymous usage data (such as which screens are opened) is counted with Google Analytics (you can turn this off in Settings).
• No ads, no in-app purchases. One-time purchase, everything included
• Save calculations to history

Results are a guide. Final dimensions and compliance with wiring regulations are the responsibility of qualified personnel.
