How to Use a Sheet Metal Nibbler

Power Nibbler

• 1

  Draw or trace a design onto the sheet metal with a marker. These are the cutting lines.

• 2

  Power on the nibbler and squeeze the trigger. Before you touch the sheet metal with the nibbler, the nibbler must be running at full speed.

• 3

  Hold the nibbler horizontal to the surface of the sheet metal.

• 4

  Move the nibbler into the sheet metal. The blade should make contact with the sheet metal.

• 5

  Push the nibbler forward and follow the cutting line. Let the nibbler do the work; do not push with force.

Manual Nibbler

• 6

  Drill a hole about 1/8 inch in front the edge of the sheet metal. Use a small drill bit, between 3/16 inch and 5/16 inch.

• 7

  Position the nibbler against the edge of the sheet metal so the tip of the nibbler touches the hole.

• 8

  Squeeze the handle of the nibbler to contract the blade and cut the sheet metal. Continue cutting along the cut lines.
