A bead roller is a type of roller used for forming and reinforcing sheet metal. Sheet metal is rolled between two beads (or other dies) to give it extra strength and rigidity. The bead roller in the shop is the Mittler 210-24M.

- Video showing the bead rolling process.
- Begin by tracing the area of your desired bead on the sheet metal.
- Next, loosen the tensioning bolt, and place the sheet metal between the two forming dies.
- Tighten the tensioning bolt by turning it two revolutions after both dies contact the sheet metal. Make sure the sheet metal is contacting the traced line where you would like the bead to begin.
- Turn the handle on the opposite side as you guide the metal through the dies. It may be easier to have a second person do this to allow the first person to more accurately guide the sheet metal through the beads.
- If you are rolling the bead to the edge of the metal, gently slip it out after finishing rolling. If you intend for you bead to stop in the middle of the metal, then stop turning the handle and loosen the tensioning bolt till the metal can slip out.
- You can adjust the tensioning bolt to make multiple passes or if you want smaller beads, but typically the tensioning bolt should be rotated twice for single passes.
